BEFORE YOUR FIRST RIDE
Make sure your bicycle fits you properly.
Your Fisher dealer should fit you with the proper size of bicycle.
There should be at least 1 inch (25 mm) clearance between the top tube and the rider when standing over the bicycle (Fig. 3). For all terrain bicycles we recommend 2-3 inches (50-75 mm) clearance.
You can also adjust the seat and handlebars to offer the best comfort and performance possible. Read pages 22-25 of this manual before attempting to make these adjustments.
Make sure you are familiar with your bicycle.
Your new Fisher bicycle is a wonder of technology. Its mechanisms provide enhanced control, more efficient pedaling, increased comfort, and great stopping power. However, these same features, if misused, can cause you to lose control of the bike.
Familiarize yourself with the use of the mechanisms on this bike. Practice riding the bike at slower speeds in a flat, empty parking lot before attempting to ride fast, or riding in more difficult conditions.
When riding slowly, do not turn the handlebars while the arms of the crankset (Fig. 2) are parallel to the ground. Modern high performance bicycles use a short wheelbase design where the front wheel may be close to the crankset. With this design it is sometimes possible at very slow speeds for your foot, or toe clips, to contact the front wheel or fender when the wheel is turned to the side and your foot is fully forward. At normal riding speeds this does not happen. At slow speeds, keep your crankarms vertical while turning.
In very rare cases some riders, particularly heavier riders on larger bikes, may experience a “shimmy” or “harmonic oscillation” or “frame vibration” at certain speeds. Experts disagree on what can cause the phenomenon but some believe it can be caused by a loose headset, improper spoke tension, or frame alignment. Riding “no-hands” or front wheel impact are among other possible causes. If you believe you are experiencing a shimmy, slow down immediately and take your bicycle directly to an authorized dealer for inspection and repair.
A bicycle is both fun and useful. To increase the utility of your bicycle, many accessories can be added. Make sure any accessories you choose to add to your bike are appropriate for your riding, and correctly attached so that they are safe. If you are unsure about the appropriateness or safety of any accessory, consult your Gary Fisher dealer.

WARNING
Never allow your foot or toe clip to contact the front wheel or
fender when turning. This may cause loss of control resulting in
personal injury.
If you believe you are experiencing a shimmy, slow down immedi-
ately and take your bicycle directly to an authorized dealer for
inspection and repair. Shimmy may lead to loss of control resulting

BEFORE EVERY RIDE- CHECKLIST
Make sure your bicycle is in proper working condition.
Spend a few moments before each ride to check your bike’s systems against the
following checklist:
Check that your wheels are straight.

to toe in used brake pads, or some new direct pull or V type brakes.
Spin each wheel to check that the rim doesn’t wobble up and down or from side
Check your tire inflation.
Inflate your tires to the air pressure recommended on the tire sidewalls (Fig.
The weight of the rider (and any load) is also a consideration in selecting tire pressure. Within the recommended inflation rates, lighter riders may find lower pressures more comfortable, while higher pressures may better support larger loads or heavier riders and help prevent pinch flats.
Use a hand-operated pump with an appropriate gauge. Gas station hoses inflate bicycle tires too rapidly and the pressure they indicate is often inaccurate.
Check your brakes.
Hand brakes
Press each brake lever to make sure that the brakes move freely and stop the bike.
The brake pads should be adjusted so they are 1 to 2 mm away from the rim when the brakes are not applied. Brake pads should be centered
The toe-in shown in Fig. 5 is to prevent squealing of the brakes. It may not be necessary

WARNING
This is not a comprehensive maintenance program. Check the entire bicycle carefully. If you spot a problem, do not ride the bike until it has been corrected. If you are not certain if your bike has a

problem, take your bike to your Gary Fisher dealer.
Disc brakes
For disc brakes where the pads contact a disc attached to the wheel hub the pads should be .25 to .75 mm away from the disc when the brakes are not applied. Always be careful inspecting disc brakes, as they may become hot after use. As with other rotating parts on a bicycle, avoid placing your fingers in the disc rotor.
Coaster brakes.
The brakes should engage with less than 60 degrees backwards rotation of the cranks (1/6 revolution). If your brakes do not firmly engage, take your bike to your Fisher dealer for service.
Also refer to Use your brakes carefully found on page 11 of this section under Ride safely.
ONE
Guide for Safe Road Riding
WARNING
If your brakes are not working properly, do not ride your bicycle.
Refer to the Brake System section of Chapter 3 or take your
bicycle to your Fisher dealer for service.
Initially practice using your brakes at slow speed. Overuse of any
brake system can cause loss of control resulting in personal injury.
Refer to ‘Use your brakes carefully’ and ‘Be careful when riding in wet
conditions’ both found on page 11 of this section under ‘Ride safely.’
The cooling fin and hub shell of Shimano Inter-M roller brakes, or disc
brakes, can get very hot and could cause burns. Do not touch the
rotor (brake disc) or hub shell for at least 30 minutes after braking.

WARNING
Failure to tighten wheel axle nuts, or failure to have wheel quick release retention mechanisms properly adjusted and closed, may cause loss of control resulting in personal injury. If you have any questions about the operation of this system, consult your Fisher dealer.
Check attachment of both wheels.
This bicycle may be equipped with a quick release wheel retention mechanism. The quick release allows the wheel to be installed and removed without tools. For proper and safe performance, read and follow these instructions carefully:
1. Check both wheels of your bicycle before
every ride.
2. Move the quick release lever to the OPEN
position and set the wheel so it firmly touches the inside of the fork ends.
3. With the lever about halfway between the
OPEN position and the CLOSED position (Fig.
6), tighten the quick release adjusting nut on the opposite end of the quick release axle until finger­tight (Fig. 7).
4. Place the quick release lever in the palm of your
hand and move the lever in a motion as shown in Figure 8. Move the lever into the CLOSED position (Fig. 10 for a front wheel or 11 for a rear wheel). At the halfway closed position of the quick release lever, you should start to feel some resistance to this motion.
5. If the lever is moved to the CLOSED position
with little or no resistance, clamping strength is insufficient. Simply return the lever to the OPEN position, tighten the quick release adjusting nut further and close the lever, testing again for resistance. When the quick release device is properly
tightened, and clamped to the closed position, the clamping force is adequate to cause metal into metal engagement (embossing) of the fork surfaces.
• Do not tighten the quick release by using the quick release lever like a wing nut (Fig. 9). This will not result in sufficient force to hold the wheel in place. For further information on correct adjustment of the quick release tension, read Figure 12.
6. Orient the quick release levers so that they do not interfere with any other bicycle part or accessory part (such as rack or fenders) and so that they will not become accidentally snagged by obstacles in the path of the bicycle (Figs. 10 and 11).
7. Do these two tests to ensure that you have
adequately performed these procedures:
• Pick the front of the bike off of the ground, and give the top of the tire a sharp downward blow (Fig. 13). The wheel should not come off, be loose, or move from side to side. If uncertain, repeat the tightening process, as shown in Steps 2-6 of these instructions.
• With the quick release lever properly adjusted and in a closed position, you will not be able to rotate the quick release lever in a circular motion parallel to the wheel (as opposed to the flipping motion used to open and close the quick release lever- see Fig. 14).
8. For the rear wheel, follow the instructions for the front wheel, and note the correct position of the quick release lever when closed (Fig. 11).
If your bicycle is equipped with axle nuts instead of quick release mechanisms (for bikes with pegs, Fig. 16, note special information below), make sure the axle nuts are tightened to 180-240 lb•in (20.3-27.1 Nm) for a front wheel, and 240-300 lb•in (27.1-33.9 Nm) for a rear wheel. Use this test to ensure that you have adequately performed these procedures:
• Pick the front of the bike off of the ground, and give the top of the tire a sharp downward blow (Fig. 13). The wheel should not come off, be loose, or move from side to side. Repeat this test again for the rear wheel.
For BMX bikes with axle nuts, where the front axle does not fit snugly inside the fork tips, a special two-stage washer must be in place on both sides of the hub for correct wheel retention (Fig. 15).
Some freestyle bikes have tubular axle extensions, called pegs (Fig. 16). For bikes with pegs, the two-stage washer goes against the fork tip as in Fig. 15, and additional washers and nut go inside the peg. For axle nuts in pegs using a 15mm socket, tighten to 220-240 lb•in (24.9-27 Nm). For axle nuts in pegs using a 19 mm socket, tighten to 350 lb•in (40 Nm).

RIDE SAFELY
Wear a helmet.
An unprotected head is highly susceptible to injury, even from the slightest contact. Wear a helmet that is comfortable, fits properly, and meets CPSC or CE safety testing standards (Fig. 17). Eye protection and appropriate cycling clothes are also recommended. Helmets should be removed when not riding the bicycle to avoid entrapment in the straps.
Know and observe your local bicycle riding laws.
Most state and local areas have specific laws for cyclists. Local cycling clubs or your state’s Department of Transportation (or equivalent) should be able to supply this information to you. A few of the more important rules of riding:
Fig. 17
• Ride single file when riding with other cyclists.
• Ride defensively (expect the unexpected). Remember: You are hard to see, and although cycling is becoming more and more common, many drivers simply are not trained to recognize the rights and special considerations of a bicycle rider.
Do not use unsafe riding practices.
While most cycling rules can be classified as common sense, it is still necessary to list a
few of the things you should NOT do on a bicycle.
• Do not ride ‘no hands’. Without a firm grip on the handlebars, the slightest road imperfection could initiate a wheel shimmy or in other ways cause the front wheel to turn unexpectedly.
• Do not ride with loose objects attached to the handlebars or any other part of the bicycle. They could get caught in the wheel spokes, cause the handlebars to turn unexpectedly, or in other ways cause loss of control.
• Do not ride while intoxicated or while using medications which might make you drowsy. Bicycles require good coordination to ride in control, and riders must be alert for hazards.
• Do not ‘ride double’. Standard bicycles are not designed to carry the additional load of a second rider. They also are much harder to balance, steer and stop with the additional weight of a second rider.
• Use proper hand signals.
• Ride on the correct side of the road (never go against traffic).
Ride defensively.
Always watch for hazardous situations. Remember, you are not as visible as a car to other bicyclists, motorists, or pedestrians. Be ready to stop or take evasive action at all times.
Watch the road.
Watch for potholes, drain grates, soft or low shoulders, and other deviations. Impact to a wheel, like improper spoke tension, can lead to wheel collapse causing loss of control. When crossing railroad tracks or drain grates, do so carefully at a 90° angle (Fig. 18). If you are not sure

of conditions, walk your bike.
Watch the parked cars you are preparing to pass.
If a car you are passing suddenly enters your lane or someone opens a car door unexpectedly, you could be involved in a serious accident.
10
Use your brakes carefully.
Always keep a safe stopping distance between you and other vehicles or objects. Adjust stopping distances and braking forces to suit riding conditions. If your bike has two hand brakes, apply both brakes at the same time. Many models of modern brakes are designed to stop a bike in wet or muddy conditions. Over-use of a powerful front brake, or use of only the front brake in an emergency situation, could cause the rear wheel to lift from the ground which could cause serious personal injury. If you feel your brakes are too powerful for your riding needs, take your bike to your dealer for adjustment.
WARNING
Avoid mis-use of the front brake
Applying excessive stopping force with the front brake may cause your rear wheel to lift off the ground, or your front wheel to slip out from under you, causing a loss of control resulting in personal injury.
No brakes, whatever their design, work as effectively in wet weather as they do in dry. Brakes, even when properly aligned, lubricated, and maintained, require greater lever pressure and longer stopping distances in wet weather. Anticipate the extra time it will take to stop. Also remember that wet weather causes reduced visibility (both for you and for motorists) and reduced traction. Use slower cornering when traction is reduced. Wet leaves and manhole covers are other wet weather hazards.
Do not submerge any bearings of your bicycle.
Bearings allow the parts of a bicycle to rotate smoothly, and water will make them rust and lose their smoothness. If any bearings on your bicycle get submerged, take your bicycle to your Fisher dealer for service.
Use special care when off-road riding.
• Never ride a road bike on unpaved trails or off road.
• Wear protective clothing including a helmet, eye protection, and gloves.
• Ride only on the trails.
• When approaching a descent, reduce your speed, keep your weight back and low,
and use the rear brake more than the front.
• Avoid rocks, branches, or depressions.
• Be considerate of other trail users. Mounting a bell on your bike will allow you to
sound a friendly warning as you approach others on the trail.
• Read and follow the IMBA Rules of the Trail (page 13).

WARNING
Be careful when riding at night.
Your bicycle is equipped with a full set of reflectors; keep them clean and in position. As
useful as these reflectors are, remember that they do not help you see, nor do they help you be seen unless light is directed on them. Use a working headlight and a tail light
when you ride at night. Also wear light, bright, and reflective clothing, especially at night, to make yourself more visible. The important thing is to
see and be seen. A number of products will help you achieve this. If you do any amount of night riding, visit your Fisher dealer to see what’s available.

DURING EVERY RIDE RIDE SAFELY
(continued)
WARNING
As with any mechanical device, every bicycle, and each part attached to it, has a limited useful life due to wear and stress. The length of that life varies according to its design, materials, maintenance, and use.
A crash can put extraordinary stress on a bicycle or its parts. Jumping your bicycle, performing bicycle stunts, severe off road riding, downhill riding, or any abnormal bike riding can be very dangerous because they increase the stress on your frame. Industry pictures and videos of these kinds of activities depict very experienced or professional riders. Frames or components under high stress can fatigue prematurely which can lead to premature or sudden failure of your bicycle frame or components. Such failure could cause a loss of control resulting in serious injury or death.
Regularly inspect your entire bicycle for signs of stress. If you choose to jump your bicycle, use it for stunts, or use it in a severe off road or downhill environment, carefully inspect your frame and components for signs of fatigue before and after each ride. Scratches, cracks, dents, deformation, or discoloration are signs of stress-caused fatigue. Although lighter frames or parts may in some cases have a longer life than heavier ones, it should be expected that light weight, high performance bicycles and parts require better care and more frequent inspections.
Remember; it is much easier to have an accident resulting in serious personal injury in these situations even if your bicycle performs as intended. Use suitable protective gear, including a certified bicycle helmet.

At Fisher, we follow these IMBA Rules of the Trail when riding our mountain bikes off road. We hope you will, too. The future enjoyment of our sport depends on good trail manners.
1. RIDE ON OPEN TRAILS ONLY.
Respect trail and road closures (ask if not sure), avoid possible trespass on private land, and obtain all required permits and authorization. Federal and State Wilderness areas are closed to cycling. Additional trails may be closed because of sensitive environmental concerns or conflicts with other users. Your riding example will determine what is closed to all cyclists!
2. LEAVE NO TRACE.
Be sensitive to the dirt beneath you. Even on open trails, you should not ride under conditions where you will leave evidence of your passing, such as on certain soils shortly after a rain. Be careful not to ride during spring thaws or any time when the weather makes for sensitive trail conditions. Observe the different types of soils and trail construction; practice low-impact cycling. This also means staying on the trail and not creating new ones. Be sure to pack out at least as much as you pack in.
3. CONTROL YOUR BICYCLE.
Inattention for even a second can cause disaster. Excessive speed is dangerous and threatens people. There is no excuse for it!
4. ALWAYS YIELD TRAIL.
Make your approach known well in advance. A friendly greeting (or bell) is considerate and works well; startling someone may cause loss of trail access. Show your respect when passing others by slowing to a walk or even stopping. Anticipate that other trail users may be around corners or in blind spots.
5. NEVER SPOOK ANIMALS.
All animals are startled by an unannounced approach, a sudden movement, or a loud noise. This can be dangerous for you, others, and the animals. Give animals extra room and time to adjust to you. In passing, use special care and follow the directions of horseback riders. Running cattle or disturbing wild animals is a serious offense. Leave gates as you found them or as marked.
6. PLAN AHEAD.
Know your equipment, your ability, and the area in which you are riding and prepare accordingly. Be self-sufficient at all times, keep your bike in good repair, and carry necessary supplies for changes in weather and conditions. A well-executed trip is a satisfaction to you and not a burden or offense to others. Keep trails open by setting an example of responsible cycling for all mountain bicyclists.
7. BE A GOOD NEIGHBOR.
The opportunity to ride on any trail brings with it a responsibility to maintain the trail, whether it be State or privately owned lands. Volunteer to assist in trail maintenance. Help your local park ranger, or form a group of your own, to clean and maintain trails in your area. Pick up trash when you see it. Be kind to other trail users. Form friendly relationships with hikers, equestrians, other trail users, and the people who own or manage the land you use.

BEFORE, DURING, OR AFTER EVERY RIDE TAKE CARE OF YOUR BIKE
Keep your bicycle clean.
To keep your bicycle in proper working condition, keep it clean. If your frame or a component is dirty, clean it with a soft damp cloth and Wrench Force® bike cleaner or similar product. If you hear a grinding or “sandy” noise coming from any bearings, your bearings need maintenance. Take your bicycle to your Fisher dealer for service.
Avoid high pressure washing systems, like those at most car washes. The high pressure can bypass bearing seals, letting water into the bearings. Water will make the bearings rust and lose their smoothness.
Avoid leaving your bicycle out in the weather.
When not riding, keep your bike in a location where it will be protected from rain, snow, sun, etc. Rain and snow can cause your bicycle to corrode. The ultraviolet radiation from the sun can fade the paint, or crack any rubber or plastic on the bicycle.
Use proper storage for your bicycle.
Improper storage is very hard on a bicycle. Before storing your bike for an extended period of time, clean and lubricate it, and polish the frame with Wrench Force® frame polish or a similar frame protectant. Hang the bicycle off the ground with the tires at approximately half pressure. Do not store near electric motors, as ozone from motors destroys rubber and paint. Before riding the bicycle again, be certain it is in good working order.
Protect your bicycle from theft.
• Keep a record of the serial number in a safe place. See page 2 for the location of the serial number on your bike. Also make sure you return your warranty card; we will keep your bike’s serial number on file.
• Register the bicycle with your local police department.
• Purchase a lock that is effective against bolt cutters and saws, and follow the recommended locking procedures.
• Use your lock. Never leave your bike unlocked while unattended, not even for a minute.
• With quick release wheels, lock both of your wheels as well as your frame. If you have a quick release seatpost binder, when locking your bike you may want to remove your seat and seatpost to prevent theft. However, avoid allowing water to enter your bicycle frame through the open seat tube of your bike.
Use good shifting techniques.
When shifting, reduce the amount of pressure on your pedals. This provides quicker, smoother shifting and will help avoid bent chains, derailleurs, and chainrings, and will also help avoid excessive chain and gear wear.
Protect your bike from accidental damage.
Park your bike in a place where it will be out of the way, and make sure it cannot fall over. Do not lay the bike on its derailleurs, as you may bend the rear derailleur or get dirt on the drivetrain. Don’t let the bike fall down, as this may cut the handlebar grips, or tear the seat. Incorrect use of bike racks can bend your wheels, as can riding over some obstacles. These are just a few of the potential hazards you and your bike may encounter. If you suspect your bicycle has been damaged or tampered with in any way, ensure that there is no problem, or take it to your Fisher dealer for inspection and repair.
14
Prevent handlebar impact damage to your frame.
With some bicycles it is possible for part, or parts, of the handlebar to contact the frame as the front wheel turns to extreme angles. If a sharp edge on any part of the handlebar were to make contact with the frame with sufficient force, it could damage the frame.
Check to see if your handlebar contacts the frame in such a way that this could happen. Prevent such damage by padding the handlebar parts, the frame, or both at the points of contact. See your Fisher dealer for recommended protection devices or materials.
Never modify your fork, frame, or components.
Your bike’s parts have been carefully designed to meet the strength and function requirements of safe riding. Modifying these parts in any way may make your bike unsafe.
As an example, some bike frames have special surface treatments which add strength and these could be removed through poor paint stripping techniques. Removing the redundant wheel retention tabs on fork tips or peg-and- eyelet style redundant retention devices is another example of how modifying a bicycle could make it less functional.
Only Fisher dual suspension frames manufactured after 1996 are compatible with double crown, triple clamp suspension forks because these forks put extra stress on the frame. Hardtail diamond frames (with no rear suspension) are not compatible with triple clamp forks. Do not install triple clamp forks on diamond construction hardtail frames. If you are unsure what type of frame you have, or what a triple clamp fork is, consult your Fisher dealer.
Any modification of your frame, fork, or components means that your bike no longer meets our specifications and will therefore void the bike’s warranty.
Care of your aluminum or OCLV frame or forks
Fisher bicycles use a variety of materials in the construction of frames and forks. If you have purchased a bicycle frame or fork of aluminum or OCLV carbon fiber composite, your frame may require special attention in its care and maintenance. See page 49 for information about your frame or fork.

Guide for Safe Road Riding
WARNING
Never modify your frameset in any way, including sanding, drilling,
filing, removing redundant retention devices from forks, or by any
other technique. Such modifications will void your warranty, may
cause your frame to fail, and may contribute to loss of control
resulting in personal injury.

UNDERSTAND THE USE OF YOUR PEDALING SYSTEM
Toe clips and straps.
If this bike came without pedals, you will choose the pedals that are best for you. Follow the manufacturer’s instructions for installation and use of these pedals.
This bicycle may be equipped with toe clips and straps. Familiarize yourself with the use of toe clips and straps. Proper fitting toe clips place the ball of your foot over the pedal axle for improved pedaling power. Shoes which might allow your foot to become trapped by the toe straps, such as those with wide, heavily patterned soles, should never be used with toe clips and straps.
If you are new to this system, practice entry and exit before your first ride. Watch the road while in motion. Looking at your pedals will make it
Fig. 19
Fig. 20
difficult to see upcoming obstacles. After first practicing in a stationary position, a flat, empty parking provides an excellent place to practice the following:
• Always keep toe straps loose enough to remove your feet quickly from the pedals to remain upright. This is done by adjusting the buckle of the toe strap (Fig. 19).
• To enter the pedals, first straddle the bike. Keep your left foot on the ground, and move the crank arm on the other side of the bike into the 5 o’clock position. To place your foot in the pedal, place the toe of your shoe on the back edge of the upside down pedal with your toes pointed slightly downward (Fig. 20). With a motion similar to scraping something off the bottom of your shoe, flip the pedal into an upright position, and insert your foot into the toe clip. This can be tricky at first, but practice will help you improve.
To mount the bike, push down on this pedal while pushing off with the other foot, and at the same time, sit on the bicycle seat. Once moving, put your other foot into the second pedal using the same technique.
• To exit this system, raise your heel so that the sole of your shoe clears the top of the pedal (Fig. 21). Withdraw your foot in an up-and­back motion, make sure your foot clears the pedal, and bring the bike to a stop.
Fig. 21
16
Always disengage at least one foot from the pedals before stopping.
WARNING
Improper use of toe clips and straps may cause loss of control resulting in personal injury. If you are uncertain about the operation of this system, consult your Fisher dealer. If your bicycle has toe clips and they do not fit or you do not want them, ask your Fisher dealer to remove them.
Clipless pedaling foot-retention systems
If this bike came without pedals, you will choose the pedals that are best for you. Follow the manufacturer’s instructions for installation and use of these pedals.
This bicycle may be equipped with pedals having a clipless foot retention system which allows you to firmly attach your shoe to the pedal without toeclips. Incorrect installation of the cleats could cause physical injury, so cleat installation should be done by your Fisher dealer.
In addition, some clipless pedals allow adjustment of the force required to enter or exit the pedals. For adjustment information, read the pedal manufacturer’s instructions supplied with your bike. If you did not receive pedal informa­tion, get a copy from your dealer, or contact us and we’ll send them to you. The following information is only meant to supplement the pedal manufacturer’s instructions.
Familiarize yourself with the use of these pedals. If you are new to clipless pedals, practice entry and exit before your first ride.
Watch the road while in motion. Looking at your pedals will make it difficult to see upcoming obstacles. After first practicing in a stationary position, an empty, flat parking lot provides an excellent place to practice the following:
• Before attempting to engage your cleated shoe into the pedal, always check both the cleats and the pedals for any contamination such as mud and stones which may interfere with entry or exit of this system, and remove it.
• To enter the first pedal, engage the front of the cleat into the front of the pedal (Fig. 22) and press down with the ball of your foot. You should hear an audible click signifying completed entry into the pedal.
Check attachment by attempting a rolling motion on the pedal (Fig.
23). If you can roll your shoe off the pedal, start the procedure again.
To mount the bike, push down on this pedal while pushing off with the other foot, and at the same time, sit on the bicycle seat. Once moving, put your other foot into the second pedal using the same technique.
• To exit the system, twist your heel laterally away from the centerline
of the bike (Fig. 24).

CHILD SAFETY AND TRAINING WHEELS
Learning to ride a bicycle is one of the joys of childhood. Our supervi­sion of young children as they learn about bikes, safety, and cycling rules of the road is critical to our children’s education. Take the time to explain the material in this, Chapter 1, to your child as he or she enters the world of cycling. And instill in your children this cardinal rule for all cyclists:
Wear a helmet whenever you ride your bike.
Training Wheels
Young children may not be able to ride a bicycle without assistance of some kind so some models of Fisher bicycles come equipped with training wheels (Fig. 25). As your child learns to ride a bicycle with
Fig. 25
Fig. 26
training wheels, make sure the child has the skills necessary to stop the bike. Until this skill is mastered, the child should never ride the bike without supervision.
The training wheels can be adjusted to promote the learning of skills such as balancing and turning. To do this, place the bike on a flat, smooth surface and then check that the tires are correctly inflated. Follow the procedures in the Drivetrain section of Chapter 3 to loosen the rear axle nuts. Stand the bike up very straight and then adjust the training wheels so that there is approximately 1/4 inch (6 mm) between the training wheels and the ground (Fig. 26). With the bike completely upright, the training wheels should be evenly spaced from the ground. Adjust the chain tension and retighten the axle nuts as shown in the Drivetrain section of Chapter 3, and inspect the wheel attachment as shown in the Wheels section of Chapter 3. As the child’s skill level grows, gradually increase the clearance between the training wheels and the ground until the training wheels are no longer required.

Inspection, Adjustment & Lubrication
A Word About Torque Specifications
Torque is a measurement of the tightness of a threaded fastener such as a screw or bolt, determined by using a torque wrench. The torque specifications in this manual are listed to help you determine the correct tightness of parts and their threaded fasteners. More than anything, these should be used to make sure you do not over tighten the fasteners. Applying more than recommended torque to a fastener does not provide extra holding power and may actually lead to damage or failure of a part. For example, over tightening bar ends can crush a handlebar. Once a part is tight enough to stay tight and be safe, it rarely does any good to tighten the part any further.
We offer a range of torque specifications. Similar parts in different bikes may require different torques due to slight differences.
There are simple function tests you should perform to make sure a part is properly tightened and we list them in this chapter. They should be performed whether a torque wrench was used or not and will suffice as a test for proper tightness if you do not have a torque wrench. As an example on pages 22-23 we show a test to determine if a stem is properly tightened to the fork. Place the front wheel between your knees and try to rotate the stem by twisting the handlebars from side to side. If the stem does not twist, it is properly tightened. While this test is somewhat subjective, it places a much greater force on the system than is required of the stem clamping force in normal riding.

Introduction
The handlebar assembly is primarily responsible for your ability to steer and control the bike. In addition, the stem and handlebars work with the seat to add comfort and efficiency to your cycling.
Inspection
Once a month, make sure the stem is in alignment with the front wheel, and that all stem bolts are tight.
Tighten a stem expander bolt (Figs. 27 and 29) to 175-260 lb•in (19.8-29.4 Nm). Tighten handlebar clamp bolts on mountain stems (Figs. 27-28) to 100-120 lb•in (11.3-13.6 NM) on welded stems, or 150­180 lb•in (17-20.3 NM) on forged stems, and 80-100 lb•in (9-11.3 NM) on 4-bolt BMX stems (Fig. 29). Tighten steerer clamp bolts on mountain bike direct connect stems (Fig. 28) to 100-120 lb•in (11.3-13.6 Nm). For BMX direct connect stems tighten steerer clamp bolts to 145 lb•in (16.4 Nm).
Some bikes are equipped with a stem having an adjustable rise, or angle. With these stems, tighten the angle adjusting bolt (Fig. 27) to 150-170 lb•in (17-20.3 Nm) after first making sure the teeth are correctly engaged, with the corresponding teeth entered between the teeth of the mating part.
If you are unsure of which type of stem your bike is equipped with, consult your Fisher dealer.
Test the security of the handlebars in the stem, and the stem in the frame, by attempting to twist the handlebars in the stem and by attempting to turn them from side to side with the front wheel locked between your knees (Fig. 31). Make sure that no cables are stretched or pinched by rotating the handlebars.
Bar-ends
Some Fisher bicycles include handlebar extensions attached to standard all terrain handlebars. These grips, or bar-ends (Fig. 30), are designed for climbing only. Never allow your bar­ends to come in contact with objects which may cause you to lose control of your bicycle. Ensure that the bar-ends face forward and away from you, the rider, and that the bar-ends are pointing upwards from the handlebars at an angle not less than 15° from parallel to the ground.
Once a month tighten your bar-end clamp bolts to 85-125 lb•in (9.6-14.1 Nm) to prevent them from rotating on the handlebars.
Fig. 30
22
WARNING
Loose bar-ends, incorrectly positioned bar-ends, or catching bar-ends on objects may cause loss of control resulting in personal injury.
Adjustment
The angle and height of the handlebars is largely a matter of personal preference blending comfort, efficiency, and balance. Your hands should be comfortable and be able to easily operate all controls. If your hands, arms, or shoulders are uncomfortable or numb you may need to adjust the handlebars or select components more suitable to your personal needs. Consult your Fisher dealer if you need help attaining comfort on your bike.
To adjust the angle of the handlebars, loosen the handlebar clamp bolt(s) on the stem just enough that the handlebars can be rotated in the stem. Position the handlebars to the desired angle, making sure they are centered in the stem. After adjustment, follow the procedures and tighten as shown in Inspection.
To change the handlebar height with a conventional stem (Figs. 27 and
29), loosen the stem expander bolt two to three turns, then tap the top of the stem expander bolt with a wood or plastic faced mallet to loosen the stem wedge. Adjust the handlebars to the desired height, and retighten following the procedures and instructions in Inspection (also note WARNING below).
Adjusting the handlebar height on a direct connect stem (Fig. 28) affects the headset bearing adjustment. This procedure requires special tools and training so this should only be done by your Fisher dealer.
Some handlebars have reinforcements in the bar tips to support bar-ends. If your handlebars have cut marks, do not cut these handlebars to a shorter length than the marks indicate (580mm minimum width) because this would remove the reinforcement.
WARNING
Cutting handlebars to be shorter than their intended length could cause
them to be weak resulting in a loss of control resulting in personal injury.
Lubrication
The stem should be lubricated once a year. To lubricate a conventional type stem (Figs. 27 and 29), loosen the stem expander bolt two or three turns, then tap the top of the expander bolt with a wood or plastic faced mallet to loosen the stem wedge. Remove the stem from the frame. Wipe the old grease off the stem and clean if necessary. Apply a thin layer of Wrench Force® synthetic grease or a similar lubrication to the section of the stem that will be inserted into the frame, including the stem wedge. Insert the stem into the frame, and follow the Adjustment and Inspection procedures in this section to re-install your stem.
Lubricate a direct connect stem once a year. This procedure requires adjustment of the headset bearings so should only be done by your Fisher dealer.

SEAT AND SEATPOST
Introduction
The seat and seatpost are your primary support on the bike. Their
adjustment is important for your comfort and pedaling efficiency. Ensure
Seat fixing bolts
Seatpost
Seatpost binder bolt

Seat fix­ing bolt
Fig. 34
that your position on the bike is correct, comfortable, and that both the seat and seatpost are securely tightened to hold this adjustment.
Inspection
Inspect the seatpost quick release lever, or seat post binder bolt, and
seat fixing bolt(s) (Figs. 33 and 34) for proper tightness every month.
For quick release levers, with the lever halfway between the OPEN position and CLOSED position, tighten the quick release adjusting nut on the opposite end of the quick release axle. Place the quick release lever in the palm of your hand and move the lever into the CLOSED position. At the halfway closed position of the quick release lever, you should start to feel some resistance to this motion. If the lever is moved to the CLOSED position with little or no resistance, clamping strength is insufficient. Return the lever to the OPEN position, tighten the quick release adjusting nut further and close the lever, and test again for resistance.
Check to ensure that the seat is secure by attempting to turn the seat and seatpost in the frame, and attempt to move the front of the saddle up and down. If the seat rotates, is loose, or moves up and down, tighten the binder bolt or quick release, or seat fixing bolts, and repeat the test. Never engage the seatpost binder lever with the seatpost out of the frame.
• Tighten seat post binder bolts (Fig. 33) to 85-125 lb•in (9.6-14.1 Nm).
• For seat fixing bolts using a 13 or 14 mm open end wrench (Fig. 34),
tighten to 180-220 lb•in (20.3-24.9 Nm).
• For single seat fixing bolts using a 6 mm allen wrench (Fig. 33),
tighten to 150-250 lb•in (17-28.3 Nm).
• For double seat fixing bolts using a 5 mm allen wrench, tighten to
80-125 lb•in (9.6-14.1 Nm).
• For seatposts with two seat fixing bolts using a 4 mm allen
wrench, tighten to 45-60 lb•in (5-6.8 Nm).

Minimum insertion mark
WARNING
Make sure that the minimum insertion mark, also called the maximum height mark (Fig. 35) remains inside the frame. A minimum of 2 1/2 inches (64 mm) of seatpost must remain in the frame. Riding with the seat raised above this height may cause loss of control resulting in personal injury or damage to your bicycle.
Adjustment
Seat angle (tilt) and fore-aft position affect both seat comfort and handlebar comfort by changing the amount of pressure placed on the handlebars. The height of the seat is very important for comfort, safety, and efficiency. With proper adjustment the right bike seat will be reason­ably comfortable even for long rides. If your saddle is not comfortable or causes numbness, you may need to adjust the saddle or select a seat more suitable to your personal needs. Consult your Fisher dealer if you need help attaining comfort on your bike.
To adjust the angle of the seat, loosen the seat fixing bolt just far enough so that the seat can be tilted fore and aft. Place a straight edge, such as a ruler, across the top of the seat to see this angle better. The correct adjustment of this angle is largely a matter of personal preference; first try riding with this angle parallel to the ground. For bikes with rear suspension, try tilting the saddle nose down slightly so that compression of the rear shock under your body weight (sag) results in a flat saddle.
The seat can also be moved forward or backward along the seatpost to increase comfort as well as adjust the distance to the handlebars. After making these adjustments, retighten the seat fixing bolt as in Inspection.
To check the seat height for greater efficiency such as that required for longer distance cycling, position the crank arms so they are parallel to the seat tube while someone holds the bicycle up. Place yourself on the seat in riding position without shoes. Your extended leg should be straight when your heel rests on the bottom pedal (Fig. 36). The correct position for you will allow the knee of your extended leg to be bent slightly when wearing your shoes, in a proper riding position; with the ball of your foot on the pedal. To adjust the height of the seat, loosen the seatpost binder bolt, or quick release lever, change the seat height, and re-tighten the seatpost lever or bolt as described in the Inspection section. Also note the WARNING on the previous page.
Lubrication
Lubricate the seatpost every year. To do this, loosen the seat post quick release lever or bolt, and remove the seatpost from the frame. Wipe the old grease off the seatpost and clean if necessary. Apply a thin layer of Wrench Force® synthetic grease or a similar lubricant to the section of the seatpost that will be inserted into the frame. Insert the seatpost into the frame, adjust to the proper height, and engage the binder lever or bolt, as explained in Inspection.

WARNING
Some medical people believe that extended riding with an improp-
erly adjusted or fitted saddle which does not support your pelvic
area correctly may cause numbness and injury to nerves and blood
vessels. Numbness can be avoided with proper bicycle fit. If you
experience numbness while riding your bicycle, have your Fisher
dealer properly fit your bicycle.

Introduction
The drivetrain consists of the parts of the bicycle that transmit power to the rear wheel. This system includes the pedals (and toeclip assemblies on some models), the crankset consisting of the left and right crank arms, the chainrings and bottom bracket assembly, the chain, and the cassette (Fig. 37). When the components of this system are working together properly shifting will be easy, your bike will be quiet, and its efficiency can reach its maximum. For bikes equipped with Shimano Nexus 7 speed drivetrains, also refer to page 34, Shimano Nexus 7 Speed Internal Shift System.

Inspection
Once a month, inspect the chain and cassette. The chain should be clean, free of
may indicate that the chainguard is loose. Lift the rear wheel off the ground and rotate the crankarms. Listen for any sounds which might indicate the crank or chain is rubbing on the chainguard. Realign the chainguard so that it does not rub, and tighten the attach­ment bolts firmly so that the chainguard cannot move.
Every 3 months, inspect your pedals and toeclips. Tighten the pedals into the crank arms to 350-380 lb•in (40.2-42.9 Nm). Tighten the right pedal by turning the pedal shaft clockwise, but tighten the left pedal in a counter-clockwise direction. Check that the pedal bearings are properly adjusted. Rotate and move the pedals right to left and up and down with your hand. If you feel any looseness or roughness in the pedal bearings, your pedal needs to be adjusted, re-greased, or replaced by your Fisher dealer. Make sure your toeclips are securely tightened to the pedal, and that the pedal reflectors are clean and securely in place.
Every 3 months inspect the crankset, including the left and right crank arms, the bottom bracket set (spindle and bearing assembly), and the chainrings. For bikes with crank bolts, tighten the crank bolt on each crank arm to 350-435 lb•in (39.5-49.2 Nm). For bikes with chainring bolts, tighten the chainring bolts to 50-70 lb•in (5.7-7.9 Nm). Check the bottom bracket bearing adjustment by first removing the chain from the chainrings, then rotate the crank so that one of the arms is parallel the seat tube. Put one hand on the crank arm and one hand on the seat tube and attempt to move the crank arm laterally toward and away from the seat tube. If the crank feels or sounds loose, the bottom bracket bearings need to be adjusted by your Fisher dealer.
Next, spin the cranks. If the motion stops abruptly or you hear a grinding noise coming from the bearings, the bearings need to be adjusted or re-greased by your Fisher dealer. Also clean the chainrings and inspect them for damage. If the teeth are bent or broken the chainring should be replaced by your Fisher dealer. Note that on some chainrings, a few teeth have a special shape to enhance shifting.
rust, and properly oiled. All links of the chain should pivot smoothly and without squeaking, and no links of the chain should be deformed. Just like the chain, keep the cassette as clean as possible. Cleaning and lubrication procedures are covered in the Lubrication section. To inspect the cassette or freewheel, take the chain off and rotate the cassette in your hands. If you hear a grinding noise or your cassette stops immediately after spinning it, the cassette may need adjustment or replacement. Take your bicycle to your Fisher dealer for service.
On single speed bikes, check the chain tension once a month. When grasped in the middle of the chain run between the front and rear sprockets, there should be a total of 1/4 to 1/2 inches (6-12 mm) total vertical movement (Fig. 38).
On bikes with a chainguard, check that the chainguard is firmly attached and correctly aligned once a month. Check the chainguard for looseness. Push side to side, and tap on it. Any movement or rattling
Every 3 months, check your chain for wear with a chain wear gauge or a ruler. Each full link of a new chain measures one inch. If 12 links of your chain measures 12 1/8 inches or more, it should be replaced. With good maintenance, a chain usually lasts 1000 to 1500 miles on the road (less on a mountain bike). Replacing the chain takes special tools and training and should only be done by your Fisher dealer.
Adjustment
Some Fisher bicycles are equipped with clipless pedals which require the installation of special cleats (provided) on specific compatible shoes which can be purchased from your Fisher dealer. Incorrect installation of the cleats could cause physical injury, so cleat installation should be done by your Fisher dealer.
Some clipless pedals allow adjustment of the force required to enter or exit the pedals. For adjustment information, read the pedal manufacturer’s instructions supplied with your bike. If you did not receive pedal information, get a copy from your dealer, or contact us and we’ll send them to you. This information is only meant to supplement the pedal manufacturer’s instructions.
To adjust the chain tension on a single speed bike, gradually loosen the rear wheel axle nuts on alternate sides of the wheel, slide the wheel to re-tension the chain, and center the wheel in the frame. Some models have a chain tensioning device which helps position the wheel. Follow the wheel Inspection and Adjustment procedures in the Wheels section to re-install the wheel. Adjusting training wheels is covered on page 18.
Adjustment of any part of the drivetrain including the crankset, bottom bracket bearings, cassette, pedals, or chain installation requires special tools and training. These services should be performed by your Fisher dealer.
Lubrication
Once a month, clean the cassette and oil the chain. Always place a rag behind the chain to avoid getting oil on the rest of the bicycle. Use Wrench Force® synthetic chain lube or similar lubrication. After oiling your chain, wipe off the excess oil with a rag. See your Fisher dealer for a recommended oil. To clean the cassette, remove the surface dirt that gathers around the cog teeth with Wrench Force® degreaser or a similar solvent, and a brush. Do not use gasoline because it’s too flammable and leaves a grease-contaminating film after evaporating. Cleaning the cassette bearings requires special tools and should only be done by your Fisher dealer. Do not disassemble the cassette.
Once a year, regrease the part of the pedal axles that thread into the crank arms.
Note: There are right and left pedals usually denoted by a letter stamped on the end of the pedal axle or on the wrench flats.
Put the right pedal on the right crank arm and the left pedal on the left crank arm. To remove the pedals turn the pedal spindle counter-clockwise for the right pedal, but clockwise for the left pedal spindle. Apply a light coat of Wrench Force® synthetic grease or a similar lubricant over all the threads, and re-install the pedals on the proper side. See your Fisher dealer for a recommended grease. Follow the tightening instructions for pedals in Inspection.
Regrease the pedal bearings and the bottom bracket bearings once a year. These operations require special tools and training, so they should only be done by your Fisher dealer.
Note: Some pedal bearings and bottom bracket bearings are permanently sealed and do not require yearly re-greasing.

Some Fisher bikes are equipped with a derailleur system. This system consists of those parts of the bicycle which allow you to shift gears. The derailleur system includes the front and rear derailleurs, the shifters or shift levers, and the shift cables.
The different types of shifters covered here are RapidFire or E-Z Fire shifters (Fig. 41, with one thumb-activated shift lever and one finger­activated shift lever, both beneath the handlebars), and Twist shifters (Fig. 42, where shifting is done by rotating a section of the handlebar grip. See Figures 41-43 to determine which type of shift system you have. Read the general information listed under (all systems) as well as the specific information for your type of shifter.
The Shimano Nexus 7 speed shift system (Fig. 43) is not a derailleur system. See Nexus information on page 34.
Shifting Pointers (all systems)
When shifting gears on a bicycle, plan ahead. Shift gears only when the pedals and chain are moving forward. Never attempt to shift gears when stopped or back pedaling. When you shift, reduce your pressure on the pedals. Excessive chain tension makes shifting difficult. Avoid shifting when going over railroad tracks or bumpy surfaces. The chain may not shift properly or may fall off.
The left-hand shift mechanism controls the front derailleur and the right-hand shift mechanism controls the rear derailleur. Shift only one lever or shifter at a time. Choose the gear combination most comfort­able for riding conditions. You should be able to maintain a constant rate of pedaling. It is not essential that various gear combinations be used in sequence.
Listen to your bike. A properly adjusted drivetrain and derailleur system is quiet. If an unusual noise follows any shift, your derailleur cable may need to be adjusted slightly (see the Adjustment section for your shifter type). If, after adjustment, the noise persists or grows louder, stop the bicycle and try to locate the noise. If necessary, ask your Fisher dealer to identify and correct any problems. For more information about your derailleur system read the following information or see your Fisher dealer.

Lubrication (all systems)
Every month, lubricate all pivot points on both the front and rear derailleurs, including the derailleur pulleys on the rear derailleur, with Wrench Force® synthetic chain lube or similar lubrication. Lubricate shift cables whenever they are being replaced. Follow the instructions for shift cable replacement in the following information.

RAPIDFIRE SHIFTERS
Inspection
Once a month, check the shift cables for kinks, rust, broken strands, or frayed ends. Also check the housing for bent ends, cuts, and wear. If you suspect a problem with your shift cables, do not ride your bicycle. Replace the cable and/or housing before riding your bicycle by following the instructions covering adjustment, or take your bicycle to your Fisher dealer for service.
Once a month, check the operation of the left shift lever/front derailleur. When the left thumb shift lever is pushed, the front derailleur should shift the chain from a smaller to a larger chainring. When the left finger shift lever is pushed, the derailleur should shift the chain from a larger to a smaller chainring. The chain should not fall off the inner or outer chainrings at any time.
Once a month, check the operation of the right shifter/rear derailleur. When the right thumb shift lever is pushed, the rear derailleur should shift the chain from a smaller to a larger cog. When the right finger shift lever is pushed, the rear derailleur should shift the chain from a larger to a smaller cog. After the shift, the rear derailleur should be positioned such that it does not rub on the chain. The chain should not fall off the inner or outer cogs at any time.
Adjustment Left Shift lever/Front derailleur
To make the low gear adjustment on the front derailleur, first shift the chain onto the smallest front chainring and the largest cassette cog. Loosen the derailleur cable clamp bolt until the cable is free. Turn the low gear adjusting screw (usually marked “L”) until the inner chain guide of the derailleur is approximately 0.5 mm from the chain. While pulling on the front derailleur cable, push the left finger shift lever several times to ensure that the shifter is in the small chainring position. Screw the adjusting barrel on the left shifter to its most clockwise position. Pull the front derailleur cable taut, insert the cable in the groove found above the derailleur cable clamp bolt, and tighten the cable clamp bolt to 32-52 lb•in (3.6-5.9 Nm).
To make the high gear adjustment on the front derailleur, shift the rear derailleur to the smallest cog. Next, turn the high gear adjusting screw (usually marked “H”) counter­clockwise until it cannot interfere with the motion of the derailleur. While pedaling the bicycle with your hand, carefully shift onto the outside chainring. Position the front derail­leur with the left thumb shift lever so that the outer chain guide of the front derailleur is approximately 0.5 mm from the chain. Re-tighten the high gear adjusting screw until it meets resistance. If you have turned it too far, the front derailleur will move toward the smaller chainring.
30
Right Shift lever/Rear derailleur
To make the high gear adjustment on the rear derailleur, shift the chain onto the smallest rear cog and the largest front chainring, then loosen the rear derailleur cable clamp bolt until the cable is free.
Stand behind the bicycle to see that the smallest rear cog, the chain, and the two derailleur pulleys are in line. If they are not aligned, turn the high gear adjusting screw (usually marked “H”) until this line is established. While pulling on the rear derailleur cable, push the right finger shift lever until the shifter is in the small cog position. Screw the adjusting barrel on the right shift lever to it’s most clockwise position. Screw the adjusting barrel on the rear derailleur to it’s most clockwise position, and then rotate it one turn counter-clockwise. Pull the shift cable taut, insert the cable into the clamp bolt groove on the rear derailleur, and tighten the cable clamp bolt to 32-52 lb•in (3.6-5.9 Nm).
To make the low gear adjustment on the rear derailleur, first turn the low gear adjusting screw on the rear derailleur (usually marked “L”) far enough counter-clockwise so that it will not restrict the movement of the derailleur. While pedaling the bicycle with your hand, carefully shift the chain onto the smallest front chainring and the largest rear cog. Do not over-shift the rear derailleur, or the chain may wedge between the large cog and
the spokes. Position the rear derailleur pulleys in line with the largest cog. Turn the low gear adjusting screw clockwise until it meets resistance. If you have turned it too far, the derailleur will move toward the outside of the bicycle. Go through the various gear combinations. Make sure the chain does not fall off when you shift.
To align the indexing system of your rear derailleur, shift the chain onto the largest front chainring, and the smallest rear cog. Push the right thumb shift lever to shift the chain onto the next smallest rear cog. If the chain makes excessive noise or does not shift, rotate the rear derailleur barrel adjuster counter-clockwise (increasing cable tension) to align the derailleur pulleys with this second cog. Do this in small increments, until the system shifts smoothly and quietly. If making this adjustment makes the chain shift to the third smallest cog, derailleur cable tension is too great. Rotate the barrel adjuster clockwise until the derailleur pulleys and the second smallest cog is aligned. Go through the various gear combinations to ensure that the chain smoothly lines up with all the rear cogs.
To adjust the middle position of the front shifter, shift the chain onto the middle front chainring and the largest rear cog. Use the barrel adjuster on the front shifter to position the inner chain guide of the front derailleur approximately 0.5 mm from the chain. Go through the various gear combinations. Make sure the chain does not fall off when you shift and that the front derailleur does not rub on any part of the crankset.
If the cable of either derailleur fails the previous inspection, do not ride the bicycle until the cable has been replaced. To do this, either follow these instructions or take your bicycle to your Fisher dealer for service. To replace a shift cable, shift the derailleurs so that the chain is on the smallest front chainring and the smallest rear cog. Note the path the derailleur cable follows, loosen the derailleur cable clamp bolt holding the bad cable, and remove the cable through the shifter. Inspect the housings. If they are damaged or rusty, replace them as well. If you replace any housings, make sure that the pieces are cut to proper length and of the correct type of housing (use the old pieces as guides) and that the housing ends are free of burrs; the cable should pass freely through these ends. Apply Wrench Force® synthetic grease or similar lubricant to the new cable and feed it through the lever and all of the cable guides and housings, and the cable clamp following the same path as the old cable. After you have done this, follow the directions for derailleur adjustment and cut the cable so no more than 2 inches (51 mm) of cable length extends beyond the cable clamp bolt. To prevent fraying of the cable end, crimp on a metal cap or apply some solder to the end of the cable.

TWIST SHIFTERS
Inspection
Once a month, check the shift cables for kinks, rust, broken strands, or frayed ends. Check the housing for bent ends, cuts, and wear. If you suspect a problem with your shift cables, do not ride your bicycle. Replace the cable and/or housing before riding by following these instructions, or take your bicycle to your Fisher dealer for service.
Once a month, check the operation of the left shifter/front derailleur. When the top of the left shifter is rotated towards you (while on the bike), the front derailleur should shift the chain from a smaller to a larger chainring. When the top of the left shifter is pushed away, the derailleur should shift the chain from a larger to a smaller chainring. After the shift, by moving the shifter slightly, you should be able to position the front derailleur such that it does not rub on the chain. The chain should not fall off the inner or outer chainrings at any time.
Once a month, check the operation of the right shifter/rear derailleur. When the top of the right shifter is rotated towards you, the rear derailleur should shift the chain from a smaller to a larger cog. When the top of the shifter is pushed away, the derailleur should shift the chain from a larger to a smaller cog. After the shift, the rear derailleur should be positioned such that it does not rub on the chain. The chain should not fall off the inner or outer cogs at any time.
Adjustment Left Shifter/Front derailleur
To make the low gear adjustment on the front derailleur, first shift the chain onto the smallest front chainring and the largest cassette cog. Loosen the derailleur cable clamp bolt until the cable is free. Turn the low gear adjusting screw (usually marked “L”) until the inner chain guide of the derailleur is approximately 0.5 mm from the chain. While pulling on the front derailleur cable, rotate the top of the left shifter away to ensure that the shifter is in the small chainring position. Screw the adjusting barrel on the left shifter to its most clockwise position. Pull the front derailleur cable taut, insert the cable in the groove found above the derailleur cable clamp bolt, and tighten the cable clamp bolt to 32-52 lb•in (3.6-5.9 Nm). To make the high gear adjustment on the front derailleur, shift the rear derailleur to the smallest cog. Next, turn the high gear adjusting screw (usually marked “H”) counter-clockwise until it cannot interfere with the motion of the derailleur.
While pedaling the bicycle with your hand, carefully shift onto the outside chainring. Position the front derailleur with the shifter so that the outer chain guide is approximately
0.5 mm from the chain. Re-tighten the high gear adjusting screw until it meets resistance. If you have turned it too far, the derailleur will move toward the smaller chainring. To adjust the middle position of the front shifter, shift the chain onto the middle front chainring and the largest rear cog. Use the barrel adjuster on the front shifter to position the inner chain guide of the front derailleur approximately 0.5 mm from the chain. Go through the various gear combinations. Make sure the chain does not fall off when you shift and that the front derailleur does not rub on any part of the crankset.
32
Adjustment Right Shift lever/Rear derailleur
To make the high gear adjustment on the rear derailleur, shift the chain onto the smallest rear cog and the largest front chainring, then loosen the rear derailleur cable clamp bolt until the cable is free. Stand behind the bicycle to see that the smallest rear cog, the chain, and the two derailleur pulleys are in line.
If they are not aligned, turn the high gear adjusting screw (usually marked “H”) until this line is established. While pulling on the rear derailleur cable, push the top of the right shifter away from you as far as it will go. Screw the adjusting barrel on the right shifter to it’s most clockwise position. Screw the adjusting barrel on the rear derailleur to it’s most clockwise position, and then rotate it one turn counter-clockwise. Pull the shift cable taut, insert the cable into it’s groove on the rear derailleur, and tighten the clamp bolt to 32-52
lb•in (3.6-5.9 Nm).
To make the low gear adjustment on the rear derailleur, first turn the low gear adjusting screw (usually marked “L”) far enough counter-clockwise so that it will not restrict the movement of the derailleur. While pedaling the bicycle with your hand, carefully shift the chain onto the smallest front chainring and the largest rear cog. Do not over-shift the rear derailleur, or the chain may wedge between the large cog and the spokes. Position the rear derailleur pulleys in line with the largest cog. Turn the low gear adjusting screw clockwise until it meets resistance. If you have turned it too far, the derailleur will move toward the outside of the bicycle. Go through the various gear combinations. Make sure the chain does not fall off when you shift.
To align the indexing system of your rear derailleur, shift the chain onto the largest front chainring, and the smallest rear cog. Rotate the shifter to shift the chain onto the next smallest rear cog. If the chain makes excessive noise or does not shift, rotate the rear derailleur barrel adjuster counter-clockwise (increasing cable tension) to align the derailleur pulleys with this second cog. Do this in small increments, until the system shifts smoothly and quietly. If making this adjustment makes the chain shift to the third smallest cog, derailleur cable tension is too great. Rotate the barrel adjuster clockwise until the derailleur pulleys and the second smallest cog is aligned. Go through the various gear combinations to ensure that the chain smoothly lines up with all the rear cogs.
If the cable of either derailleur fails the previous Inspection, do not ride the bicycle until the cable has been replaced. Inspect the housings. If they are damaged or rusty, replace them as well. If you replace any housings, make sure that the pieces are cut to proper length and of the correct type of housing (use the old pieces as guides) and that the housing ends are free of burrs; the cable should pass freely through these ends.
To install a new derailleur cable in a Twist shifter, shift the chain to the smallest rear cog and smallest front chainring. Loosen the derailleur cable clamp bolt on the derailleur and note the path the cable follows.
Remove the cable through the shifter. Open the small cable window on the shifter (denoted by a small ‘door’) to expose the leaded end of the cable.
Install the new cable by threading the cable through the shifter. Apply Wrench Force® synthetic grease or similar lubricant to the new cable and feed it through all of the cable guides, housings and the cable clamp following the path of the old cable. Reattach and adjust the derailleur cable as explained in Adjustment. After you have done this, cut the cable so that there is no more than 2 inches (51 mm) of cable length exposed beyond the cable clamp bolt. To prevent fraying of the cable end, crimp on a metal cap or apply some solder to the end of the cable.

Introduction
The Shimano Nexus 7 speed shift system consists of those parts of the bicycle which allow you to shift gears including the shifter, rear hub, and shift cable. The shifting mechanism is enclosed, keeping the shifting system lubricated for low maintenance.
Shifting Pointers
When shifting gears, plan ahead. Shifting gears is best performed when coasting, stopped, or back pedaling. If you must shift while pedaling, reduce your pressure on the pedals. Excessive chain tension makes shifting difficult. Choose the gear most comfortable for riding conditions. You should be able to maintain a constant rate of pedaling.
Listen to your bike. A properly adjusted shift system is quiet. If an unusual noise follows any shift, your shift cable may need to be adjusted. If after adjustment the noise persists or grows louder, stop the bicycle and try to locate the noise. If necessary, ask your Fisher dealer to identify and correct any problems. For more information about your shift system consult your Fisher dealer.
Inspection
Before every ride, make sure the Nexus hub gears are properly adjusted. With the shifter in 4th gear, the red lines on the hub’s pulley and the cog joint bracket (Fig. 44) should line up.
Once a month, check the shift cable for kinks, rust, broken strands, or frayed ends. Also check the housing for bent ends, cuts, broken coils and wear. If you suspect a problem with your shift cable, do not ride your bicycle. Replace the cable and/or housing before riding your bicycle by following these instructions, or take your bike to your Fisher dealer for service.
Adjustment
If the red lines on the hub’s pulley and the cog joint bracket do not line up when the shifter is in 4th gear, adjust the gear cable tension. Rotate the shifter barrel adjuster (Fig. 45) until this alignment is achieved. Shift to 1st gear, then back to 4th, and recheck the adjustment.
Fig. 46
34
Lubrication
Lubricate shift cables with Wrench Force® synthetic chain lube or a similar lubricant whenever they are being replaced. Lubricate the Nexus hub bearings once a year. This procedure takes special tools and training, so should be done by your Fisher dealer.
To replace the shift cable, loosen the cable fixing bolt and remove the cover on the front of the shifter secured by a phillips head screw. Slide the cable end cover (Fig. 46) forward. Note the path of the old cable as you remove it. Install a new cable in the shifter following the old path, and reattach the cable fixing bolt. Follow the instructions in Adjustment to finish installation.
HEADSET AND FORK
Introduction
The fork is responsible for holding the front wheel of your bicycle. The headset (Fig. 47) is the bearing system which allows the steering of your bike by rotation of the fork, stem, and handlebars.
On freestyle bikes, a rotor (Fig. 48) allows the handlebars to turn 360 degrees for freestyle tricks without interference from the brake cables.
Inspection
Once a month inspect the headset of your bicycle. Stand over the top tube of your bicycle with both feet on the ground. Apply the front brake firmly while you rock the bicycle forward and backward. If your bike is not equipped with a front brake, do this inspection by turning the front wheel to be across or perpendicular to the pushing force.
Look, listen, and feel for looseness of the headset bearings. To check that the headset is not too tight, slowly rotate the fork and handlebars to the right and left.
If the fork makes any grinding noises, or feels like it sticks or binds at any point in the rotation, the bearings may be too tight. If your headset bearings are too loose or too tight, do not ride the bicycle. Take it to your Fisher dealer for maintenance.
The rotor should not interfere with the headset function in any way. Look and listen for irregular noises or rubbing from the rotor.
Adjustment
Headset adjustment requires special tools and training, and should only be performed by your Fisher dealer. Further adjustment of the rotor is covered in the Brake System section in the following pages.

Introduction
The brake system allows you to control the speed of your bicycle, and this function is critical to your safety. The brake system can be difficult to adjust properly without the proper tools and training. If you are unsure of the brake adjustment, or suspect any problem, do not ride your bicycle. Take your bicycle to your Fisher dealer for service. It is strongly recommended that adjustment of critical components such as brakes be done by your Fisher dealer. If you need more specific informa­tion regarding your brake system, contact your Fisher dealer.
Inspection
Before every ride make sure your brakes are working properly. Before every ride check that the brake pads are in proper position (Fig. 50).
Pad and rim should be
parallel
Your rims are part of the braking system, so keep them clean at all times. Check that there is no oil, grease, or other dirt on the rims.
Every month check your bike’s brake cables and housing. Check the cables for kinks, rust, broken strands, and frayed ends. Check the housing for bent ends, cuts, stretched coils, and wear. Replace any part of your brake cables or housing which do not pass inspection.
Every month, inspect your brake pads for wear. Brake pads have shallow grooves in their braking surfaces to channel water from the rim. If any of these grooves are less than 2 mm deep (or 1 mm deep for direct-pull brakes, Fig. 49), replace the pads.
Every 3 months for caliper brakes tighten pad fixing bolts to 40-60 lb•in (4.5-6.8 Nm). Tighten caliper fixing bolts to 70-85 lb•in (7.9-9.6 Nm).
Every 3 months for direct pull brakes (Fig. 49), cantilever brakes (Fig.
51), or U-brakes (Fig. 52) tighten pad fixing bolts to 70-80 lb•in (7.9-9 Nm). Tighten arm fixing bolts to 70-85 lb•in (7.9-9.6 Nm).
Every 3 months tighten lever clamp bolts (Fig. 53) to 40-60 lb•in (4.5-
6.8 Nm).

Adjustment
Adjust the brake pads so they are 1.5 mm to 2 mm away from the rim when the brakes are not applied. This is done by turning the brake cable adjusting barrels on the brake calipers (or brake levers if equipped with direct pull brakes). To bring the pads closer to the rims, turn the adjusting barrel counter-clockwise. To move the pads away from the rim, turn the adjusting barrel clockwise.
If the pads of direct-pull or caliper brakes cannot be adjusted close enough to the rim in this manner, loosen the cable anchor bolt until the cable is loose. Screw the barrel adjuster all the way in clockwise. Hold the brake pads against the rim, and re-tighten as in Inspection. Changing the brake cable length in a cantilever brake requires special tools and training, so should only be done by your Fisher dealer.
To adjust the alignment of the brake pads, loosen the brake pad fixing bolt and align the pad so that the pad surface and the rim surface meet correctly (Fig. 50). The toe-in
shown in Figure 50 is to prevent squealing of the brakes. It may not be necessary to toe in used brake pads, or some new direct pull or V type brakes.
When adjustment is complete, tighten the pad fixing bolt to 70-80 lb•in. (7.9-9 Nm). To center the brakes, rotate the centering screw (Figs. 49 and 51). After the brakes are adjusted, test the brakes by applying maximum braking force to the levers. Ensure that the cable does not slip, that the pads close toward the rim at right angles, and that the pads do not contact the tire.
If you are unsure of the brake adjustment, or suspect any problem, do not ride your bicycle. Take your bicycle to your Fisher dealer for service. It is strongly recommended that adjustment of critical components such as brakes be done by your Fisher dealer.

Cable Installation
To install a brake cable in a direct-pull or caliper-type brake, note the path of the old cable, loosen the brake cable anchor bolt and remove the worn cable. Turn the adjusting barrel on the brake caliper clockwise so that the threads on the adjusting barrel are not exposed above the caliper. Grease the new cable and reinstall, feeding it along the same path as the old cable. Make sure that the cable’s leaded end is seated properly in the brake lever body and that the housing is properly seated in the lever. After threading the cable through the anchor bolt, follow the directions for brake adjustment in the Inspection and Adjustment sections. Finally, cut the cable so that no more than 2 inches (51 mm) extends beyond the anchor bolt. Crimp a metal cap or place a bit of solder on the end of the cable to prevent fraying.
Installing a brake cable in a cantilever brake requires special tools and training, so should only be done by your Fisher dealer.

Direct-pull Brake Levers
Direct-pull brakes (Fig. 49) have increased leverage and stopping power, and use special brake levers to manage that power. With all brakes use only levers recognized as compat­ible, like those supplied with your bike.
If your direct-pull brake levers offer adjustable braking force, read and follow the manufacturers instructions supplied with your bike before making any such adjustment. Like any braking system, failure to properly use and maintain your direct-pull braking system can result in a loss of control and injury.
WARNING
If you are not certain your brakes are working properly, or if you
suspect a problem with your brake cables do not ride your bicycle.
Refer to the instructions in the appropriate section of this manual or
take your bicycle to your Fisher dealer for service.

Inspection- Inter-M Roller Brake
Before every ride, make sure the Nexus Inter-M roller brake (Fig. 55) is working properly. After about 15mm of brake lever movement, the brakes should engage enough to stop the bike.
Adjustment- Inter-M Brake
To decrease the amount of lever travel necessary to engage the brakes, loosen the barrel adjuster locknut, and rotate the brake cable barrel adjuster (Fig. 55) counterclockwise. To increase lever travel, rotate the barrel adjuster clockwise. Test the lever for correct travel. When the desired setting is achieved, rotate the barrel adjuster locknut clockwise until finger tight to hold this adjustment.
Lubrication
Every 3 months, lubricate your brake lever pivots with Wrench Force® synthetic chain lube or a similar light oil.
Lubricate brake cables with a thin layer of Wrench Force® synthetic grease or a similar lubricant when installed.
Cable Installation
To install a brake cable in Shimano Inter M brakes, note the path of the old cable, loosen the brake cable anchor bolt and remove the worn cable. Turn the adjusting barrel on the brake or lever fully clockwise. Grease the new cable and reinstall, feeding it along the same path as the old cable. Make sure that the cable’s leaded end is seated properly in the brake lever body and that the housing is properly seated in the lever. After threading the cable through the anchor bolt, follow the directions for brake adjustment in the Adjustment section.
After the brakes are adjusted, test the brakes by applying maximum braking force to the levers. Ensure that the cable does not slip in the cable anchor bolt.
Finally, cut the cable so that no more than 2 inches (51 mm) extends beyond the anchor bolt. Crimp a metal cap or place a bit of solder on the end of the cable to prevent fraying.

ROTOR AND CALIPER BRAKES
Introduction
The brake system allows you to control the speed of your bicycle, and this function is critical to your safety. The brake system can be difficult to adjust properly without the proper tools and training. If you are unsure of the brake adjustment, or suspect any problem, do not ride your bicycle. Take your bicycle to your Fisher dealer for service. It is strongly recommended that adjustment of critical components such as brakes be done by your Fisher dealer. If you need more specific informa­tion regarding your brake system, contact your Fisher dealer.
Rotor
A rotor (Fig. 57) allows the handlebars on a freestyle bike to rotate 360 degrees despite having a cable operated front brake. Since the rotor is a connection between the brake lever and the brake, its function is critical to good stopping power and safety.
Once a month inspect the rotor for proper function. Watch the bearing unit as you rotate the handlebars 360 degrees. It should not move up or down, or tilt. When the brake lever is applied, the rotor should apply the brake firmly while the bearing unit remains parallel to the upper and lower cable stops. If the bearing unit tilts either when the brakes are applied, or when the handlebars are rotated, the rotor needs adjustment.
To adjust the rotor, first ensure that both lower barrel adjusters are flush with (do not show above) the lower cable stop, and the bearing unit should be resting on the lower cable stop. Your rear brake adjustment must be made with the bearing unit in this position.
The bearing unit should be parallel to the upper and lower cable stops. If it is tilted, there is slack in one of the cables. Pull each end, one at a time. To see which cable has slack at the bearing unit. Remove the slack through the barrel adjuster. When even pull is achieved tighten all barrel adjuster locknuts.
If you are unsure of the brake adjustment, or suspect any problem, do not ride your bicycle. Take your bicycle to your Fisher dealer for service. It is strongly recommended that adjustment of critical components such as brakes be done by your Fisher dealer.

BRAKE SYSTEMS- DISC BRAKES
Introduction
The brake system allows you to control the speed of your bicycle, and this function is critical to your safety. The brake system can be difficult to adjust properly without the proper tools and training. If you are unsure of the brake adjustment, or suspect any problem, do not ride your bicycle. Take your bicycle to your Fisher dealer for service. It is strongly recommended that adjustment of critical components such as brakes be done by your Fisher dealer.

attachment bolts to 25-35 lb•in (2.8-4 Nm). For cable actuated brakes, tighten the cable clamp bolt to 50-70 lb•in (5.7-7.9 Nm).
The rotor (Fig. 58) is part of the braking system, so keep it clean at all times. Check that there is no oil, grease, or other dirt on the rotor. Remove the brake pads from the caliper during heavy cleaning by pulling outward to release the spring clip. Do not use cleanser, degreaser, or solvents to clean the disc. To clean discs, use isopropyl alcohol.
With hydraulic actuated disc brakes, check the brake hose for kinks or leakage every month. Replace any part of hydraulic hose which does not pass inspection. Replacing hydraulic hose requires re-adjustment of the braking system with special tools and training and should only be done by your Fisher dealer. Do not let brake hydraulic fluid contact the bicycle as it may remove paint.
With cable actuated disc brakes check your bike’s brake cables and housing every month. Check the cables for kinks, rust, broken strands, and frayed ends. Check the housing for bent ends, cuts, stretched coils, and wear. Replace any part of your brake cables or housing which do not pass inspection.
Every month, inspect disc brake pads for wear. If disc brake pads are less than 1.0 mm thick they should be replaced.
meant to supplement the disc brake manufacturer’s manual.
Inspection- Disc Brakes
Before every ride make sure your brakes are working properly. Check that the brake pads are in proper position. The pads should allow 0.25 to 0.75mm clearance from the disc when the brakes are not applied. Spin the wheel. When the brake lever is not pressed, the brake pads should touch as little as possible on the rotor (disc). Do not touch the disc brake rotor after hard use as it may be very hot.
Before every ride squeeze the lever firmly. It should not be possible to pull the lever fully to the handlebar. If the lever of a hydraulic activated disc brake feels spongy, or can be pressed with little resistance, the system may need to be bled to remove air bubbles. Take your bike to your Fisher dealer for service. If the lever of a cable actuated disc brake can be pulled to the handlebar, follow the adjustment instructions in the following section.
Once a month tighten the brake mounting bolts, and any adapter mounting bolts using a 5mm allen wrench, to 100-110 lb•in (11.3-12.4 Nm). For adapter bolts using a 4mm allen wrench, tighten to 60-65 lb•in (6.8-7.3 Nm). Tighten rotor attachment bolts holding the rotor to the hub to 45-55 lb•in (5-6.2 Nm).

WARNING
Disc brakes can get very hot and could cause burns. Do not touch the rotor (brake disc) for at least 30 minutes after braking.
Keep away from parts like rotors and spokes when rotating. They may cause personal injury.
Adjustment- Disc Brakes
On some models of Fisher bicycles, the distance from the handlebar grip to the brake lever can be adjusted to fit your hand size. To adjust the reach, squeeze the brake lever while turning the reach adjustment screw (Fig. 59). On brake levers for hydraulic activated disc brakes, the reach adjustment screw may be at position ‘B’. Try the different settings until you find a position that fits your hands. After adjusting the brake reach, you may need to re-adjust the brake cable length by rotating the barrel adjusters, as explained in the following paragraphs.
Disc brakes are essentially self adjusting as long as the brake is correctly aligned and centered over the disc rotor. If the rotor is rubbing, the brake caliper alignment may need adjustment. To make this adjustment, first loosen the brake attachment bolts. While applying the lever fully, gradually tighten each attachment bolt as specified in Inspection.
Do not operate the disc brake lever when the rotor is not in the caliper. Self adjusting disc brakes automatically set the distance from the pad to a point of contact, usually the rotor. However, if the lever is pulled with the rotor removed from the brake, the pad clearance will be set from the opposing pad. This results in only 0.5mm between the pads so the rotor can not be re-inserted in the brake. To fully open the pads, remove both brake pads by pulling outward on the small pad tab. With a 12mm box end wrench, push each piston out as far as it will go being careful not to press on the brake pad locating post. Reinstall the pads by sliding them into position, reinstall the wheel, and check the brake adjustment as in Inspection.
If the brake lever of a cable actuated disc brake can be pulled fully to the handlebars, adjust the brake cable tension. To do this turn the brake cable adjusting barrels found on the brake levers. To decrease the lever travel necessary to actuate the brake, turn the adjusting barrel counter-clockwise. To increase lever travel, turn the adjusting barrel clockwise. If the lever travel cannot be adequately adjusted in this manner, loosen the cable anchor bolt on the brake until the cable is loose. Screw the barrel adjuster all the way in clockwise. Pull the cable taught and follow the procedures in Inspection to re-tighten the cable anchor bolt. After the brakes are adjusted, test the brakes by applying maximum braking force to the levers. Ensure that the cable does not slip.
Lubrication
Every 3 months, lubricate your brake lever pivots with Wrench Force® synthetic chain lube or a similar light oil. Disc brakes require no lubrication.
Lubricate brake cables with a thin layer of Wrench Force® synthetic grease or a similar lubricant when installed.

Make sure that the cable’s leaded end is seated properly in the brake lever body and that the housing is properly seated in the lever. After threading the cable through the anchor bolt, follow the directions in the Inspection and Adjustment sections. Finally, cut the cable so that no more than 2 inches (51 mm) extends beyond the anchor bolt. Crimp a metal cap or place a bit of solder on the end of the cable to prevent fraying.

Introduction
Tire
The wheels allow your bike to roll down the road smoothly so the integrity of your bicycle wheels is crucial. Their structural soundness and their relationship to the performance of your brakes are of great importance.
The best maintenance of a wheel is preventative maintenance. Be aware of the things that can go wrong, so you can stop trouble before it happens.
Fig. 60
Rim
section, or consult your Fisher dealer.
Before installing tires, make sure a rim strip is in place which completely covers the rim
web (wall to wall) so that all spoke holes are completely covered.
Check that the wheels are straight and round by spinning them. If the rim does not
spin evenly, have your wheel trued by your Fisher dealer.
Make sure your tires are inflated to the pressure indicated on the tire sidewalls. Use a gauge and a bicycle pump whenever possible. Avoid filling your tires at gas stations. Because of the greater pressure and volume of air their pumps release, blowouts are very possible. Inspect your tires for wear and any other damage.
If a tire has any cuts or separations which go through the tire, making any part of the inner tube visible, or if any part of the tire casing shows through the tire tread (running surface) or knobs are worn or missing, replace the tire.
Make sure your rims are clean. Dirty or greasy rims render your brakes ineffective. Wipe your rims with a clean rag or wash them with soap and water, rinse, and let them air dry.
Every week, make sure that there are no loose, damaged, or broken spokes. If a wheel is not in good condition, both the effectiveness of the brakes and the strength of the wheel are greatly reduced.
Every month, check that both hub bearings are properly adjusted. Lift the front end of the bicycle off the ground with one hand and attempt to move the rim laterally, left to right. Look, feel, and listen for any looseness in the hub bearings. Spin the wheel, and listen for any grinding or other unusual noises. If the hub feels loose or makes any noise, the hub needs an adjustment. Repeat these procedures for the rear wheel.
Every month, check your rims for wear. On adult-size bicycles there are wear indicators in the braking surface, either a continous indented band or several small spherical indentations at even intervals around the rim. If the braking surface has worn so that any part of these indicators is no longer visible, have your dealer replace the rim.
Inspection
Before every ride, check that your quick release hubs are in their closed (locked) position, or that your wheel axle nuts are tight. For further information on adjusting quick release hubs, see the Adjustment
42
WARNING
If there is movement between the axle and the hub, or you suspect the hub may need an adjustment, do not ride your bicycle. Take your bicycle to your Fisher dealer for service.
Make sure the rim strip covers all of the spoke holes or spoke heads. If they are exposed they may puncture the inner tube and may cause loss of control resulting in personal injury.

This bicycle may be equipped with a quick release wheel retention mechanism. The quick release allows the wheel to be installed and removed without tools. For proper and safe performance, read and follow these instructions carefully:
1. Check both wheels of your bicycle before
every ride.
2. Move the quick release lever to the
Fig. 61
OPEN position and set the wheel so it firmly
touches the inside of the fork ends.
3. With the lever about halfway between the
OPEN position and the CLOSED position
(Fig. 61), tighten the quick release adjusting nut on the opposite end of the quick release axle until finger-tight (Fig. 62).
4. Place the quick release lever in the palm of your hand and move the lever in a motion as shown in Figure 63. Move the lever into the
Fig. 63
CLOSED position (Fig. 65 for a front wheel
or 66 for a rear wheel). At the halfway closed position of the quick release lever, you should start to feel some resistance to this motion.
5. If the lever is moved to the CLOSED position with little or no resistance, clamping strength is insufficient. Simply return the lever to the OPEN position, tighten the quick release adjusting nut further and close the lever, testing again for resistance. When the quick release device is properly tightened, and clamped to the closed position, the clamping force is adequate to cause metal into metal engagement (embossing) of the fork surfaces.
Fig. 65
• Do not tighten the quick release by using the quick release lever like a wing nut (Fig. 64). This will not result in sufficient force to hold the wheel in place. For further information on correct adjustment of the quick release tension, read Figure 67.
6. Orient the quick release levers so that they do not interfere with any other bicycle part or accessory part (such as rack or fenders) and so that they will not become accidentally snagged by obstacles in the path of the bicycle (Figs. 65 and 66).

7. Do these two tests to ensure that you have adequately performed
these procedures:
• Pick the front of the bike off of the ground, and give the top of the tire a sharp downward blow (Fig. 68). The wheel should not come off, be loose, or move from side to side. If uncertain, repeat the tightening process, as shown in Steps 2-6 of these instructions.
• With the quick release lever properly adjusted and in a closed position, you will not be able to rotate the quick release lever in a circular motion parallel to the wheel (as opposed to the flipping motion used to open and close the quick release lever- see Fig. 69).
8. For the rear wheel, follow the instructions for the front wheel, and note the correct position of the quick release lever when closed (Fig. 66).
If your bicycle is equipped with axle nuts instead of quick release mechanisms (for bikes with pegs, Fig. 71, note special information below), make sure the axle nuts are tightened to 180-240 lb•in (20.3-27.1 Nm) for a front wheel, and 240-300 lb•in (27.1-33.9 Nm) for a rear wheel. Use this test to ensure that you have adequately performed these procedures:
• Pick the front of the bike off of the ground, and give the top of the tire a sharp downward blow (Fig. 68). The wheel should not come off, be loose, or move from side to side. Repeat this test again for the rear wheel.
For BMX bikes with axle nuts, where the front axle does not fit snugly inside the fork tips, a special two-stage washer must be in place on both sides of the hub for correct wheel retention (Fig. 70).
Some freestyle bikes have tubular axle extensions, called pegs (Fig.
71). For bikes with pegs, the two-stage washer goes against the fork tip as illustrated in Figure 70, and additional washers and nut go inside the peg. For axle nuts in pegs using a 15mm socket, tighten to 220-240 lb•in (24.9-27 Nm). For axle nuts in pegs using a 19mm socket, tighten to 350 lb•in (40 Nm).

WARNING
Failure to tighten wheel axle nuts, or failure to have wheel quick release retention mechanisms properly adjusted and closed, may cause loss of control resulting in personal injury. If you have any questions about the operation of this system, consult your Fisher dealer.
If you cannot keep the proper pressure in your tires, you probably have a leak in the tube. The section on pages 46 and 47, Tire Installation, includes instructions to fix the tube leak. If you do not have the proper tools, take the bike to your Fisher dealer for repair.
Lubrication
Regrease wheel bearings every year. This requires special tools and training, so should only be done by your Fisher dealer.
Lubricate quick releases once a year. Apply several drops of Wrench Force® synthetic lube or a similar light oil where the quick release lever rotates in the quick release body.

Inspection, Adjustment & Lubrication
Introduction
Your reflectors are an important part of your bicycle’s safety equipment.
Do not remove the reflectors from your bicycle. They are there for your safety.
Inspection
Every three months, make sure all the nuts and bolts holding the front, rear, pedal, and wheel reflectors are tight. Check that front and rear reflectors are oriented so that their reflective surfaces are perpendicular to the ground, and that all reflective surfaces are clean and in good condition. The front reflector should point directly forward, and the rear should point directly back. The rear reflector should be at least three inches below the top of the seat.
Adjustment
To adjust the front and rear reflectors, bend the metal bracket, or loosen the attachment screw on plastic brackets, reposition, and then re-tighten the screw.

TIRE INSTALLATION
Follow these steps when repairing a tube in the event of a flat tire, or
when replacing a worn tire.
1. Open the brake quick release lever. For caliper type brakes, the quick release lever is on the brake itself. For direct-pull brakes, disconnect the link arm from the curved pipe (Fig. 72). For cantilever brakes or U-brakes (Fig. 73), disengage the brake by removing the link-wire from the brake caliper. After opening the quick release mechanism, the brake will spring open allowing the tire to pass between the brake pads.
Note: If you are removing the rear wheel, shift the chain to the smallest chainwheel and the smallest cog of the cassette.
For Nexus 7 speed rear wheels (Fig. 74), undo the brake and shift
cables. Be careful not to touch the rear hub which may be hot from

braking. To release the brake cable, press the cable carrier arm forward and the cable clamp bolt rearward so that the bolt aligns with the carrier’s larger diameter hole, and then pull outward to disengage the cable clamp bolt. Then slide the brake cable stop forward to remove it from the brake arm. To release the shift cable, first put the shifter in 1st gear. Pull the cable's housing out of the shift cable housing stop. Rotate the shift cable fixing bolt until the washer flats align with the slit in the cog joint bracket, and remove the cable.
2. For wheels with axle nuts, gradually loosen the nut on alternate sides of the hub. This prevents altering the bearing adjustment of the hub. For wheels with quick release devices, release the quick release lever and for front wheels unscrew the quick release adjustment nut 3 full turns. Remove the wheel from the fork tips.
Note: For the rear wheel on bikes with a derailleur, hold the rear derailleur up and back while removing the wheel. For rear wheels on bikes without rear derailleur, slide the wheel forward and lift the chain off the rear cog. Then remove the wheel.
3. Deflate the tire completely. Remove the tire from the rim with your hands or tire lever tools. Do not use sharp objects such as a screwdriver to remove the tire.
4. If you are repairing a tube leak, repair the puncture on the tube with a tube patch, or replace the tube. Check the inside of the tire and rim to be sure there are no foreign objects protruding through or stuck to the insides. Make sure the rim strip covers all of the spoke heads. Inspect the tire for wear, and any other damage. If a tire has any cuts or separations which go through the tire, making any part of the inner tube visible, or if any part of the tire casing, such as threads or other material, shows through the tire tread (running surface) replace the tire.

6. Inflate the tube until it begins to take shape. Place the tube in the tire. Insert the tube valve stem through the hole in the rim and carefully mount the tire onto the rim using your hands. Be careful not to pinch the tube between the rim and the tire when mounting the tire.
7. Inflate the tire to about half pressure while checking that the tire bead is properly seated in the rim. Deflate the tire again. This will help avoid any pinching of the tube.
8. Inflate the tire to the pressure indicated on the side of the tire. Place the wheel back in the frame making sure that the axle is inserted all the way into the fork tips.
Note: For the rear wheel on derailleur bikes, place the chain on the smallest cog when installing the wheel. For rear wheel on bikes without a derailleur, slide the wheel fully forward and place the chain over the cog.
9. Re-install and adjust the quick release or tighten the axle nuts as shown in the Wheels section.
For single speed bikes, retension the chain (with the chain tensioners, if so equipped). Also readjust training wheels and reinstall the coaster brake arm strap, if so equipped. Center the wheel in the frame, and gradually tighten the axle nuts on alternating sides of the hub. Tighten the brake strap bolt.
To install the brake cable on a Nexus rear hub, slide the brake cable housing stop into the slot on the brake arm. Pull the cable back and press the cable carrier arm forward until the cable clamp bolt can be inserted though the large diameter hole. Slide the bolt forward into the smaller diameter hole and make sure it is properly engaged so that it cannot come out.
To install the shift cable on Shimano Nexus rear hubs, align the washer flats of the shift cable fixing bolt (Fig. 74) with the slit in the cog joint bracket, and with the cable towards the center of the hub, slide in the bolt. Wrap the cable counterclockwise around the cog joint bracket, lay the cable in the fork, and pull the housing until there is enough slack to install the housing into the housing stop. Check that the gear cable tension is correctly adjusted.
10. For bikes with rim brakes, re-install the brake link-wire or re-install the brake
pipe into the link arm.
11. Test the brake to make sure it is properly adjusted.
12. Spin the wheel to see that it is centered and the wheel turns freely without
rubbing.

Schraeder and Presta Valves
There are two styles of valves used on Fisher bicycles (Fig. 75). The larger diameter Schraeder valve is similar to those found on cars and it’s use is the same. Just remove the valve cap, attach an air pump with a Schraeder fitting, and inflate. Put the cap back on, as the cap keeps dirt and debris out of the valve.
The Presta valve is also known as a French valve. To inflate a Presta valve, remove the valve cap, if present. Presta valves seal very tightly, and require a lot of pressure to open them initially, so after unscrewing the valve nut, depress the nut with your finger to open the valve (This should let a little air out). Inflate using a Presta valve fitting. After inflation, tighten the valve nut against the valve stem until finger-tight. This provides the same function as the valve cap on a Schraeder valve.

change, carefully test the bike in a low traffic area until you are familiar with its performance.
Introduction
If your bicycle is equipped with a suspension fork, ensure that it is operating properly before every ride. Read the Suspension Fork Owner's Manual you received with your bike. If you did not receive a fork manual, get one from your dealer, or contact us and we’ll send you one. The following information is only meant to supplement the fork manufactur­er’s manual.
Inspection
Suspension forks require regular care, maintenance, and lubrication. All bolts must be tight, and critical clearances must be maintained.
After every 5-10 hours of riding, or after riding in extremely wet and muddy conditions, lift the shock boots and inspect and clean the seal area. Remove all dirt and clean the entire area with a soft cloth. Do not use solvents or other cleaning agents which may degrade the suspen­sion lubrication. Make sure the boots are in the correct position to protect the seals and keep contaminants from damaging the fork.
Tighten crown pinch bolts as specified in the Suspension Fork Owner’s Manual supplied with your suspension fork
Do not ride with less than the minimum clearances between the top of the tire and the bottom of the fork crown. Minimum clearance for your fork is listed in the Suspension Fork Owner’s Manual supplied with your suspension fork.
Adjustment
The stiffness of the suspension fork spring, also called the preload, may be adjustable. For starters, adjust your suspension fork so that the fork sags (compresses when you sit on the bike in a normal riding position) about 5-10mm, or 10-20mm for long travel forks with over 65mm of travel. After first riding with this adjustment, try different adjustments to suit your riding style.
To increase preload of your suspension fork, follow the instructions in
Damping controls the speed of the suspension fork action during compression or
Changing your suspension will affect handling and braking characteristics. After making a
Lubrication
Suspension forks require regular lubrication to work smoothly and to provide long seal life. Follow the Lubrication and Maintenance instructions in the Suspension Fork Owner’s Manual supplied with your suspension fork.
WARNING
Failure to keep suspension bolts tight, or to maintain adequate
clearances between tire and fork crown or braking mechanism
may cause loss of control resulting in personal injury.

CARE OF YOUR ALUMINUM OR OCLV FRAME
Carbon fiber, aluminum and the aluminum parts of your bicycle (like dropouts) are not as ductile as steel. Attempting to make adjustments to a part by bending or twisting it poses a risk of breaking it. Readjustment of frame alignment is not recommended. If the frame has been damaged, bring it to your Fisher dealer so it can be sent to the Fisher factory for repair.
Tolerances for press fits and thread fits are critical. Pressing a part which is too large, or misaligned, may break the frame or part. Over-torquing a threaded fastener may ruin the threads or break the part. Be sure bottom bracket and rear derailleur threads are clean and well greased before insertion. Start threads by hand, not with a wrench. Torque specifications for bottom bracket cup threads is 430-610 lb•in (48.6-68.9 Nm). Torque specifications for rear derailleur threads is 70-85 lb•in (7.9-9.6 Nm).
The seat lug of aluminum road bikes is designed to accept seat posts with 27.12 to
27.20 mm, 29.12 to 29.20, or 31.45 to 31.60mm outer diameter. The seatpost should be measured for conformity to this tolerance prior to installation. Use adequate lubrication to prevent seizing of the aluminum seatpost to the aluminum seat lug or tube.
When cleaning frame parts, do not use solvents or harsh chemicals. Remove road film with a soft rag and a mild detergent and water solution. Use of industrial solvents for cleaning or paint removal may damage the paint.
Removing paint from any frameset requires special techniques and great care. Harsh abrasives will remove frame material, possibly weakening the bicycle. See your Fisher dealer for more information.
Modifying the frame in any way will void the manufacturers warranty and may be unsafe.
Frame Repair
Most types of frame damage can be repaired at the Fisher factory. You must send your frame back to Fisher through an authorized Fisher dealer.

Inspection
After every 10 hours of use, inspect the shock mounting bolts and the pivot bolts for tightness. This procedures requires removing the nut from the bolt or axle, cleaning the threads thoroughly, applying a thread-locking compound (Loctite 242 is excellent) and re-tightening. Tighten shock mounting bolts (Figs. 78 and 79) to 61-75 lb•in (6.9-8.5 Nm) and pivot bolts to 100-110 lb•in (11.3-12.4 Nm). Tighten linkage bolts (Fig. 79) to 15-20 lb•in (1.7-2.2 Nm).
Adjustment
When adjusting the seat height on a Joshua full suspension bike (Fig.
78), do not lower the bottom of the seat post to any position closer than 1.5" (38 mm) to the top of the swingarm. Allowing the swingarm to contact the seat post could damage your bicycle.

adjustment nut to compress the spring. To make the suspension softer, rotate the nut to lengthen the spring. If the spring on your shock does not offer the desired range of adjustment, replacement springs are available with different spring rates. See your Fisher dealer.
On models using air shocks, the preload is adjusted by changing the air pressure inside
the shock using the high pressure shock pump provided (Fig. 81).
The recommended preload (initial spring pressure) adjustment of the rear shock, whether air spring or coil spring, allows a slight compres-

sion of the spring when your weight is placed on the bike called “sag”. Correct adjustment allows between 15-25% sag at the rear shock. Less sag means a firmer, “hardtail” feel, while more sag will make the bike more compliant with a softer feel. For Joshuas, there should be about 8-10mm of shock compression. For Sugars, about 4mm compression is a good starting point.
To increase the preload on coil/over shocks (Fig. 80), rotate the
Sugar suspension setup for RockShox SID
SID shocks have two springs; the main spring extends the shock and resists compres­sion. The negative spring works to compress the shock during its first few millimeters of travel, giving the shock a plush feel that’s sensitive on small bumps.
In the SID main chamber, pump up the pressure to be equal in PSI to half your body weight in pounds. In the SID negative chamber, use about one half that pressure.
Smaller riders sit further ahead on the bike than taller riders. Sitting further ahead of the pivot, smaller riders don’t apply as much leverage to the shock. For this reason, they may benefit from slightly more pressure in the negative spring.
To adjust the damping, try 2-3 clicks in from fully fast.
This is a good place to start. You should experiment in small increments to find what works best for your position, terrain, body weight, and riding speed.
On some models of shocks, the damping range is adjustable to control the speed of the spring. Read your shock owner’s manual to learn more about damping adjustments.
Changing your suspension will affect handling and braking characteristics. After making a change, carefully test the bike in a low traffic area until you are familiar with its performance.

REAR SUSPENSION
Sugar suspension setup for Cane Creek AD series
Cane Creek shocks also have two springs, and they work similarly to
the RockShox. The difference is that the Cane Creek is self-adjusting.
With a Cane Creek rear shock, pump up the pressure to around 25-35
PSI less than your body weight in pounds.
With models that provide damping adjustment, try 2-3 turns in from
fully fast.
This is a good place to start. You should experiment in small increments to find what works best for your position, terrain, body weight, and riding speed.

Lubrication
No lubrication is required for the shock or the pivot of your Fisher full suspension bike. The pivot uses a Teflon impregnated composite bearing. Avoid all lubricants as they may damage the composite bearing. For best results and long life, simply wash the shock and pivot area with a solution of soap and water, or just water.

TREKKING ACCESSORIES-
Lights, rack, fenders, and bell
ON
Introduction
To enhance their capacity for commuting, trekking bicycles are equipped with a selection of accessories which may include a generator light set for improved visibility, fenders to keep the bike and rider drier, a rack to carry belongings, or a bell to sound warnings or greetings. All accessories must be properly maintained for best service.
Inspection
Once a month check to ensure that the following nuts and bolts are tight. Tighten the fender adjusting nuts to 30-40 lb•in (3.5-4.5 Nm). Tighten fender and rack attachment bolts to 50-60 lb•in (5.7-6.8 Nm). If your bike is equipped with other accessories they should also be
Fig. 82
inspected monthly.
Lights
The lights on your Trekking bike have been designed and installed on your bike for extra safety in conditions with poor visibility resulting from either fog or dark. These lights are powered by a generator so no batteries are required. However, for your lights to provide light the generator must be properly installed, adjusted, and engaged in the ON position, with your bicycle rolling with enough speed to illuminate the light bulbs, usually about 3-4 miles per hour.
To turn on your generator and thus your lights, press down on the generator body as shown in Figure 82. This will engage the generator and the lights will come on as soon as your bike is rolling. You should visually check that both the headlight and taillight are illuminated as you start to ride. To turn off your lights, rotate the generator body away from its contact with the tire until you hear a click. If you have done this correctly, the generator should stay in the OFF position.
WARNING
When stopped at an intersection or for any other reason, your
lights will turn off, decreasing your visibility to other vehicles.
Check your lights. For best results, the lights should be carefully aimed to provide the best blend of brightness and distance for your style of riding, as well as the best location in front of your bike (generally centered directly in front of the bike). The lenses of the lights should be kept clean. Remember that your field of vision may be diminished when riding at night, even with the headlight on. You should adapt your riding speed for safety. Also remember that although you have your lights on, you will be less visible than during daytime riding.
Always ride defensively!
52
In addition to aiming the lights on your bike and keeping the lenses clean for maximum illumination, you may have to replace the light bulbs occasionally. It is recommended that you do this every six months because no warning will precede the burning out of a light bulb. By replacing the bulbs periodically you will reduce the risk of a bulb burning out during use of the light which would leave you without a functioning light.
The wiring on your trekking bike lighting system may be partially enclosed inside the frameset to protect the wires. Avoid pulling, tearing, or cutting these wires, as damaging the wires will cause the light to cease to function.
Installing bulbs
To install a new bulb, locate the lens set-screw on the back of either the taillight or head light (Fig. 83). Remove the screw with a Phillips screwdriver. After the screw has been completely removed, rotate the lens 1/4 turn clockwise and lift the lens assembly off the bulb mount. You may then unscrew the bulb, being careful not to crush the glass of the bulb.
Being careful not to dislodge the wire in the base of the bulb mount, install a new bulb and reverse the disassembly procedure to reassemble your light. The correct bulbs can be purchased from your Fisher dealer. The bulb has its volts and wattage listed on its base. The most commonly used bulbs are:
• Headlight- 6V 2.4w
• Taillight- 6V 0.6w
