ABOUT THIS MANUAL
It is important for you to understand your new bicycle. By reading this manual before you go out on your first ride, you’ll know how to get better performance, comfort, and enjoyment from your new bicycle.
It is also important that your first ride on your new bicycle is taken in a controlled environment, away from cars, obstacles, and other cyclists.
GENERAL WARNING
Bicycling can be a hazardous activity even under the best of circumstances. Proper maintenance of your bicycle is your responsibility as it helps reduce the risk of injury. This manual contains many “Warnings” and “Cautions” concerning the consequences of failure to main­tain or inspect your bicycle. Many of the warnings and cautions say “you may lose control and fall.” Because any fall can result in seri­ous injury or even death, we do not repeat the warning of possible injury or death whenever the risk of falling is mentioned.
A SPECIAL NOTE FOR PARENTS
It is a tragic fact that most bicycle accidents involve children. As a parent or guardian, you bear the responsibility for the activities and safety of your minor child. Among these responsibilities are to make sure that the bicycle which your child is riding is properly fitted to the child; that it is in good repair and safe operating condition; that you and your child have learned, understand and obey not only the appli­cable local motor vehicle, bicycle, and traffic laws, but also the common sense rules of safe and responsible bicycling. As a parent, you should read this manual before letting your child ride the bicycle. Please make sure that your child always wears an approved bicycle helmet when riding.

CORRECT FRAME SIZE
1-2in.
When selecting a new bicycle, the correct choice of frame size is a very important safety consideration. Most full sized bicycles come in a range of frame sizes. These sizes usually refer to the distance between the center of the bottom bracket and the top of the frame seat tube.
For safe and comfortable riding there should be clearance of no less than 1 - 2 inches between the groin area of the intended rider and the top tube of the bicycle frame, while the rider straddles the bicycle with both feet flat on the ground.
The ideal clearance will vary between types of bicycles and rider preference. This makes straddling the frame when off the saddle easier and safer in situations such as sudden traffic stops. Women can use a men’s style bicycle to determine the correct size women’s model.
The following chart and diagram will help you make the correct choice. Rider leg length refers to approximate pant inseam.

RIDING POSITION
Saddle Height
In order to obtain the most comfortable riding position and offer the best possible pedaling efficiency, the seat height should be set correctly in relation to the rider’s leg length. The correct saddle height should not allow leg strain from over-extension, and the hips should not rock from side to side when pedaling. While sitting on the bicycle with one pedal at its lowest point, place the ball of your foot on that pedal. The correct saddle height will allow the knee to be slightly bent in this position. If the rider then places the heel of that foot on the pedal, the leg should be almost straight.
Under no circumstances should the seat post project from the frame beyond its “Minimum Insertion” or “Maximum Extension” mark. If your seat post projects from the frame beyond these markings, the seat post
or frame may break, which could cause you to lose control and fall. Prior to your first ride, be sure to tighten the saddle adjusting mechanism properly. A loose saddle clamp or seat post binder can cause damage to the bicycle or can cause you to lose control and fall. Periodically check to make sure that the saddle adjusting mechanism is properly tightened.
Reach
To obtain maximum comfort, the rider should not overextend his or her reach when riding.

Handlebar Height
Maximum comfort is usually obtained when the handlebar height is equal to the height of the seat. You may wish to try different heights to find the most comfortable position.
Handlebar Binder Bolt
Exceeds 2 1/2” (64mm)
Threadless headsets and clamp-on stems are not adjustable. Please refer to page 23 for instructions on installation.
The stem’s “Minimum Insertion” mark must not be visible above the top of the headset. If the stem is extended beyond this mark, the stem may break or damage the fork’s steerer tube, which could cause you to lose control and fall.
Failure to properly tighten the stem binder bolt, the handlebar binder bolt, or the bar end extension clamping bolts may compromise steering action, which could cause you to lose control and fall. Place the front wheel of the bicycle between your legs and attempt to twist the handlebar/stem assembly using a reasonable amount of force. If you can twist the stem in relation to the front wheel, turn the handlebars in relation to the stem, or turn the bar end extensions in relation to the handlebar, you must tighten the appropriate bolts accordingly.

10
Page 18
Helmets
It is strongly advised that a properly fitting, ANSI or SNELL approved, bicycle safety helmet be worn at all times when riding your bicycle. In addition, if you are carrying a passenger in a child safety seat, they must also be wearing a helmet.
The correct helmet should:
- be comfortable
- be lightweight
- have good ventilation
- fit correctly
- cover forehead
Always wear a properly fitted helmet which covers the forehead when riding a bicycle. Many states require specific safety devices. It is your responsibility to familiarize yourself with the laws of the state where you ride and to comply with all applicable laws, including properly equipping yourself and your bike as the law requires. Reflectors are important safety devices which are designed as an integral part of your bicycle. Federal regulations require every bicycle to be equipped with front, rear, wheel, and pedal reflectors. These reflectors are designed to pick up and reflect street lights and car lights in a way that helps you to be seen and recognized as a moving bicyclist. Check reflectors and their mount­ing brackets regularly to make sure they are clean, straight, unbroken and securely mounted. Have your dealer replace damaged reflectors and straighten or tighten any that are bent or loose.
11
Page 19
Reflectors
Your bicycle is supplied with one front (white), one rear (red), two wheel (white), and four pedal (orange) reflectors. (Please Note: Sidewalk bikes, 12” and under, may not have reflectors.) These are an important safety and legal requirement, and should remain securely fitted and in good, clean condition at all times. Periodically, inspect all reflectors, brackets and mounting hardware for signs of wear or damage. Replace immediately if damage is found. Some bicycles will require you to install your reflectors onto your bicycle. Please refer to the following section for instructions on all the types of bicycle reflectors.
Fork Mount Reflector Bracket Assembly
First insert one washer onto the hex bolt and insert hex bolt through the reflector bracket and then through the fork. Next, insert a second washer onto the bolt and thread a hex nut onto the bolt behind the fork. Tighten bolts until snug, making sure the reflector is in an upright position. See diagram at the right.
Front Reflector Mount with Caliper Brake Assembly
First remove the hex nut from the back of the fork and pull the brake from the fork. Insert a spacer, washer and the reflector bracket on to the caliper bolt. Insert the caliper bolt back into the fork and secure firmly with a concave spacer, washer and the hex nut. Finally, adjust the reflector such that it is in an upright position. See dia­gram at the right.
12
Page 20
Seat and Handlebar Mounting Reflectors
First attach the reflector to the reflector bracket with the reflector screw, see the top diagram. Next, remove the clamp screw and open the clamping reflector bracket. Place clamping reflector bracket around the handlebar or seatpost. If the clamp is too loose, insert the shim inside of the clamp. Tighten the clamp screw to hold reflector assembly in place, see the second diagram. Finally, adjust the reflector assembly in place and ensure that it is upright and facing away from the bike.
Seatstay Mount Reflector Bracket Assembly
First insert one washer onto the hex bolt and insert hex bolt through the reflector bracket and then through the seatstay bridge. Next, insert a second washer onto the bolt and thread a hex nut onto the bolt behind the seatstay bridge. Tighten bolts until snug, making sure the reflector is in an upright position. See diagram at the right.

RIDING SAFELY
General Rules
When riding obey the same road laws as all other road vehicles, including giving way to pedestrians, and stopping at red lights and stop signs.
For further information, contact the Road Traffic Authority in your State.
Ride predictably and in a straight line. Never ride against traffic.
Use correct hand signals to indicate turning or stopping.
Ride defensively. To other road users, you may be hard to see.
Concentrate on the path ahead. Avoid pot holes, gravel, wet road markings, oil, curbs, speed bumps, drain grates and other obstacles.
Cross train tracks at a 90 degree angle or walk your bicycle across.
Expect the unexpected such as opening car doors or cars backing out of concealed driveways.
Be extra careful at intersections and when preparing to pass other vehicles.
Familiarize yourself with all the bicycle's features. Practice gear shifts, braking, and the use of toe clips and straps, if fitted.
If you are wearing loose pants, use leg clips or elastic bands to prevent them from being caught in the chain. Wear proper riding attire and avoid open toe shoes.
Don't carry packages or passengers that will interfere with your visibility or control of the bicycle. Don't use items that may restrict your hearing.
Do not lock up the brakes. When braking, always apply the rear brake first, then the front. The front brake is more powerful and if it is not correctly applied, you may lose control and fall.
Maintain a comfortable stopping distance from all other riders, vehicles and objects. Safe braking distances and forces are subject to the prevailing weather conditions.
14
Page 22
Wet Weather
IT IS RECOMMENDED TO NOT RIDE IN WET WEATHER
- In wet weather you need to take extra care.
- Brake earlier, you will take a longer distance to stop.
- Decrease your riding speed, avoid sudden braking and take corners with additional caution.
- Be more visible on the road.
- Wear reflective clothing and use safety lights.
- Pot holes and slippery surfaces such as line markings and train tracks all become more hazardous when wet.
Night Riding
IT IS RECOMMENDED TO NOT RIDE AT NIGHT
- Ensure bicycle is equipped with a full set of correctly positioned and clean reflectors.
- Refer to p. 12-13 and p. 93 of this manual.
- Use a properly functioning lighting set comprising of a white front lamp and a red rear lamp.
- If using battery powered lights, make sure batteries are well charged.
- Some rear lights available have a flashing mechanism which enhances visibility.
- Wear reflective and light colored clothing.
- Ride at night only if necessary. Slow down and use familiar roads with street lighting, if possible.
Pedaling Technique
- Position the ball of your foot on the center of the pedal.
- When pedaling, ensure your knees are parallel to the bicycle frame.
- To absorb shock, keep your elbows slightly bent.
- Learn to operate the gears properly. (Refer to p. 17-19)
15
Page 23
Hill Technique
- Gear down before a climb and continue gearing down as required to maintain pedaling speed.
- If you reach the lowest gear and are struggling, stand up on your pedals. You will then obtain more power from each pedal revolution.
- On the descent, use the high gears to avoid rapid pedaling.
- Do not exceed a comfortable speed; maintain control and take additional care.
Cornering Technique
Brake slightly before cornering and prepare to lean your body into the corner. Maintain the inside pedal at the 12 o'clock position and slightly point the inside knee in the direction you are turning. Keep the other leg straight, don't pedal through fast or tight corners.
Please refer to pages 103-4 for braking techniques and pages 104-7 for gear shifting techniques.
Rules for Children
To avoid accidents, teach children good riding skills with an emphasis on safety from an early age. Children should be super­vised by an adult.
1. Always wear a properly fitted helmet.
2. Do not play in driveways or the road.
3. Do not ride on busy streets.
4. Do not ride at night.
5. Obey all the traffic laws, especially stop signs and red lights.
6. Be aware of other road vehicles behind and nearby.
7. Before entering a street: Stop, look right, left, and right again for traffic. If there's no traffic, proceed into the roadway.
8. If riding downhill, be extra careful. Slow down using the brakes and maintain control of the steering.
9. Never take your hands off the handlebars, or your feet off the pedals when riding downhill.
The Consumer Protection Safety Commission advises that the riding of small wheel diameter bicycles at excessive speeds can lead to instability and is not recommended.
Children should be made aware of all possible riding hazards and correct riding behavior before they take to the streets.
- Do not leave it up to trial and error.

GEARS - HOW TO OPERATE
Derailleur Gears
Most multi-speed bicycles today are equipped with what are known as derailleur gears. They operate using a system of levers and mecha­nisms to move the drive chain between different sized driving gears or cogs. The purpose of gears is to let you maintain a constant, steady pedaling pace under varying conditions. This means your riding will be less tiring without unnecessary straining up hills or fast pedaling down hill. Bicycles come with a variety of gear configurations from 5 to 27 speeds. A 5-6 speed bicycle will have a single front chainwheel, a rear derailleur, and 5 or 6 cogs on the rear hub. Bicycles with more gears will also have a front derailleur, a front chainwheel with 2-3 cogs, and up to 9 cogs on the rear hub.
Operating Principles
No matter how many gears, the operating principles are the same. The front derailleur is operated by the left shift lever and the rear derailleur by the right. To operate you must be pedaling forward. You can not shift derailleur gears when you are stopped or when pedaling backwards. Before shifting ease up on your pedaling pressure. For a smooth gear change when approaching a hill, shift to a lower gear BEFORE your pedaling speed slows down too much. When coming to a stop, shift to a lower gear first so it will be easier when you start riding again. If, after selecting a new gear position, you hear a slight rubbing noise from the front or rear gears, gently adjust the appropriate shifter using the barrel adjusters until the noise goes away. For opti­mal performance and extended chain life, it is recommended that you avoid using the extreme combinations of gear positions (diagram p.
18) for extended periods.

Hand Grip Shifters
Some bicycles are now being equipped with a shifting mechanism called Grip Shift™, which is built into the handlebar grips and does not make use of separate levers. The actuating mechanism is built into the inside part of the grip that the web of the thumb and index finger closes around. To select a lower gear, twist the right shift­er toward you to engage a larger rear cog. You can shift one gear at a time by moving the Grip Shift™ one click, or through multiple gears by continued twisting. By twisting the left shifter forward or away from you, a smaller chainwheel can be selected. To select a higher gear, twist the right shifter forward or away from you to engage a smaller rear cog. To engage a larger front chainwheel, twist the left shifter towards you. Single shifts can be achieved by twisting one click at a

Basic Maintenance
The following procedures will help you maintain your bicycle for years of enjoyable riding.
For painted frames, dust the surface and remove any loose dirt with a dry cloth. To clean, wipe with a damp cloth soaked in a mild detergent mixture. Dry with a cloth and polish with car or furniture wax. Use soap and water to clean plastic parts and rubber tires. Chrome plated bikes should be wiped over with a rust preventative fluid.
Store your bicycle under shelter. Avoid leaving it in the rain or exposed to corrosive materials. Riding on the beach or in coastal areas exposes your bicycle to salt which is very corrosive. Wash your bicycle frequently and wipe or spray all unpainted parts with an anti-rust treatment. Make sure wheel rims are dry so braking performance is not affected. After rain, dry your bicycle and apply anti-rust treatment.
If the hub and bottom bracket bearings of your bicycle have been submerged in water, they should be taken out and re-greased. This will prevent accelerated bearing deterioration.
If paint has become scratched or chipped to the metal, use touch up paint to prevent rust. Clear nail polish can also be used as a preventative measure.
Regularly clean and lubricate all moving parts, tighten components and make adjustments as required. (Refer to Parts 4 and 5 of this manual for further details). The use of alloy components and BED, SATIN and TITANIUM surface treatments minimizes the number of places where rust can surface.

Page 28
Storage
Keep your bicycle in a dry location away from the weather and the sun. Ultraviolet rays may cause paint to fade or rubber and plastic parts to crack. Before storing your bicycle for a long period of time, clean and lubricate all components and wax the frame. Deflate the tires to half pressure and hang the bicycle off the ground. Don't store near electric motors as ozone emissions may effect the rubber and paint. Don't cover with plastic as "sweating” will result which may cause rusting. Please notice that your bicycle warranty does not cover paint damage, rust, corrosion, dry rot or theft.
Security
It is advisable that the following steps be taken to prepare for and help prevent possible theft.
1. Maintain a record of the bicycle’s serial number, generally located on the frame underneath the bottom bracket.
2. Register the bicycle with the local police.
3. Invest in a high quality bicycle lock that will resist hack saws and bolt cutters. Always lock your bicycle to an immovable object if it is left unattended.

Includes 20", 24” and 26" Wheel Mountain Bikes Assembly is the same for men’s and women’s bikes.
Getting Started
Open the carton from the top and remove the bicycle. Remove the straps and protective wrapping from the bicycle. Inspect the bicycle and all accessories and parts for possible shortages. It is recommended that the threads and all moving parts in the parts package be lubricated prior to installation. Do not discard packing materials until assembly is complete to insure that no required parts are accidentally discarded. Assemble your bicycle following the steps that pertain to your model. Note: Your bicycle may be equipped with different style components than the ones illustrated.
Handlebars
Remove the protective cap from the handlebar stem wedge and loosen the Allen key bolt using the 6mm Allen key. Some models may use a 13mm hexagonal bolt instead of an Allen key bolt. Place the handlebar stem into the top of the head tube, ensuring that all cables are free of tangles. Tighten the stem bolt observing the minimum insertion mark and checking that the forks and the handlebars are facing forward. Check the headset for smooth rotation and that the top nut is secured tightly. Loosen the 6mm Binder Bolt and rotate the handlebar forward so the levers are at a 45 degree angle below the handlebar. Retighten the Binder Bolt to ensure the handlebar does not rotate in the stem.

Forks
There are two different types of forks that vary in styles and dimensions. One type is a rigid fork (Figure 1) consisting of stationary tubing with curved blades. The other type is a suspension fork (Figure 2) consisting of stanchion tubes riding on elastomers or springs inside of a straight fork leg. This mechanism acts as a shock absorber with a specified amount of travel that varies between models. Some suspen­sion forks are not adjustable and are very difficult to disas­semble. If service is needed on a suspension fork, consult a professional bicycle repair technician.

Drop-out
Do not attempt to disassemble a suspension fork yourself. Consult a professional bicycle repair technician.
Check the tightness of the headset and the fork. Rotate the fork checking for smoothness. If it feels like the fork is binding, then an adjustment will need to be made to the headset. Move the fork in a push/pull manner checking for tightness. If any play is detected, loosen the top nut, adjust the bearing cup, and retighten the top nut. Recheck the rotation and tightness. If necessary, readjust until a smooth rotation is achieved without backward or forward move­ment. If your bike is equipped with a suspension fork, check that the fork compresses and rebounds smoothly. To do this, place the fork dropouts against the ground, push and release the handlebar. The fork will generally compress 1-2” and rebound quickly. Most elastomer type forks will gradually soften with use.

Seat and Seat Post
Attach the seat to the seat post by loosening the nuts on the seat clamp. Insert the tapered end of the seat post into the seat clamp until it is at the top of the clamp. Partially tighten the nuts on the seat clamp until the seat is snug, but can still be turned. Insert the seat assembly into the frame of the bicycle and adjust the seat to the proper height. The seat post must be inserted to at least the “Minimum Inser­tion” line marked on the seat post. If equipped with a quick release skewer; tighten the adjusting nut by hand and move the quick release lever to the closed position. You should feel considerable resistance while moving the lever. If not, re-open and re-tighten the lever, then move it to the closed position so it is in line with the frame as pictured. If equipped with a binder clamp; Insure the lip on the binder clamp is fitted completely against the top of the seat tube of the frame. With the seat post inserted, tighten the binder bolt securely. Position the top of the seat parallel with the ground. Push the front of the seat up and down to firmly mesh the serrations together. The serrations must mesh completely together to insure a stabilized rid­ing position. Securely tighten the nut on the seat clamp. If there is a nut on both sides of the clamp, tighten each one by alternating from one to the other. Check for tightness by twisting the seat from side to side, and from front to back. If the seat moves at the seat clamp or quick release, reposition and re-tighten the appropriate clamping mechanism.
NOTE: Comfort Series (CS) bicycles may be equipped with a suspension seat post (See Diagram-bottom left). Some suspension posts can be adjusted for stiff­ness using the preload adjusting screw. Turning the 6mm Allen screw Clockwise will decrease travel and make the suspension stiffer, while turning the 6mm Allen screw Counter-clockwise will increase travel and make the suspension less rigid.

Note: In addition to normal assembly, please be aware that the preload adjusting screw must be flush with the bottom of the post. Some bicycles may come equipped with a shim that should be positioned over the lower half of the seat post and inserted into the seat tube of the frame. Failure to do this may cause irreparable damage.
The seat post must be inserted so that the minimum insertion mark cannot be seen. The quick release mechanism must be tightened securely to prevent a sudden shift of the seat when riding. Failure to do this may cause loss of bicycle control.

Dust Cap
Pedals & Crank Set
Look for the letters “R” for right, and “L” for left, stamped on each pedal spindle. Start each pedal spindle by hand to avoid stripping the threads. Tighten with a 15mm narrow open ended wrench. Note that the right hand pedal attaches to the chainwheel side crank arm with a right-hand (clockwise) thread. The left pedal attaches to the other crank arm and has a left-hand (counter-clockwise) thread. It is very important that you check the crank set for correct adjustment and tightness before riding your bicycle. New cranks may become loose with initial use, refer to p. 83-86 for proper crank set adjustment and maintenance. Once the pedals have been installed, remove the dust caps from the center of each crank arm. Using a 14mm socket wrench, tighten the spindle nuts securely (approx. 350 in. lbs.) and replace the dust caps.
Attachment of an incorrect pedal into a crank arm can strip pedal threads and cause irreparable damage. Before your first ride, please check to insure your pedals are attached correctly.

Front Wheel
Check the wheel hub before attaching it to the fork by rotating the threaded axle. It should be smooth with no lateral movement. Insert the front wheel into the fork dropouts. Tighten the wheel nuts using the appropriate 14mm or 15mm wrench. Spin the wheel checking for trueness. Some bicycles have wheel axles that incorporate a Quick Release (QR) mechanism. This allows easy wheel removal without the need for tools. The mechanism uses a long bolt with an adjusting nut on one end, and a lever operating a cam-action tensioner on the other. If the wheel is fitted with a Quick Release type axle, turn the adjusting nut so that the locking lever is moved to the closed position with a firm action. At the halfway closed position of the quick release lever, you should start to feel some resistance to this motion. Do not tighten the quick release by using the quick release lever like a wing nut. If the quick release lever is moved to the closed position with no resistance, clamping strength is insufficient. Move the quick release lever to the open position, tighten the quick release adjusting nut, and return the quick release lever to the closed position.
Correct Quick Release Axle Setting
1. To set, turn the lever to the open position so that the curved part faces away from the bicycle.
2. While holding the lever in one hand, tighten the adjusting nut until it stops.
3. Pivot the lever towards the closed position. When the lever is halfway closed, there must be firm resistance to turn it beyond that point. If resistance is not firm, open the lever and tighten the adjusting nut in a clockwise direction.
4. Continue to pivot the lever all the way to the closed position so that the curved part of the lever faces the bicycle.

6. Note that the same procedure applies when operating a quick release seat post binder mechanism.
7. Turn the bicycle upright using the kickstand to support it.
If you can fully close the quick release without wrapping your fingers around the fork blade for leverage, and the lever does not leave a clear imprint in the palm of you hand, the tension is insufficient. Open the lever, turn the adjusting, and try again. Continue until the QR lever closes properly. Secondary retention devices are not a substitute for a correct quick release adjust­ment. Failure to properly adjust the quick release mechanism can cause the wheel to wobble or disengage, which could cause you to lose control and fall, resulting in serous injury or death.
Front Brake
Determine which type of brake your bike is equipped with and refer to the appropriate assembly instructions. For more information on brake adjustment and maintenance, refer to p. 77-80.
Cantilever Brakes - Utilizing a Link Wire
If fitted with cantilever type brakes, insert the brake cable into the link wire lead, and notch the cable end into the slot of the left brake arm. Loosen the anchor bolt on the right brake arm and slide the brake cable under the tabbed washer. Squeeze both brake arms together so the brake shoes hit the rim, pull all slack out of the brake cable, and tighten the anchor bolt. With the cable fitted, the straddle holder should sit 10-20mm above the reflector bracket. Adjust the brake shoes using a 10mm wrench so that they are parallel with the rim and are positioned 1-2mm away from the rim. Several adjustments may be necessary to achieve the correct brake position.

Cantilever Brakes - Utilizing a Straddle Cable
The length of the straddle cable, the height of the straddle hanger, and the brake pad-to-caliper arm position all have an effect on brak­ing power. Generally, the straddle cable bridge is set low and close to the tire for maximum braking force. The straddle cable should be high enough, however, to adequately clear the tire (and any debris that may stick to the tire) or to fit over the front reflector hanger. In the event of brake cable failure, the front reflector hanger would prevent the straddle cable from catching in the tire and locking up the front wheel. The straddle cable length (when adjustable) is set to transfer as much force to the brake pads as possible. For the most efficient transfer of force, the straddle cable and the line between the cantilever pivot and the cable anchor should form a right angle (90 degrees). If the force is not at a right angle, part of the force gets wasted in pulling on the brake post, which has no effect on braking.
V-Style Brakes
If not already assembled, take the brake noodle from the parts box and slide the cable through the larger opening. The cable housing will then seat into the end of the noodle. Slide the cable through the cable lead on the end of the left brake arm, this will cause the noodle to fit into the lead. Slip the brake cable boot over the cable and posi­tion it between both brake arms. Next, loosen the 5mm anchor bolt at the end of the right brake arm and slide the cable under the retain­ing washer. Pull the slack out of the cable making sure a distance of 39mm or more remains between the end of the lead and the start of the anchor bolt. Once the cable is secured to the brake arms, engage the brake lever several times, checking the position of the brake shoes at the rim. The brake shoes should be 1mm away from the rim when in a relaxed position. When the brake lever is engaged, the brake shoe should hit the rim flush (never the tire) with the front brake pad touching the rim slightly before the rear. This is called “toeing-in” your brake shoe. If this position is not achieved, adjustments to the brake shoe are required. Loosen the brake shoe hardware and reposi­tion the brake shoe. It may take several shoe and cable adjustments before the required position is accomplished.

Check your Brakes
Press each brake lever to make sure that there is no binding and that the brake pads press hard enough on the rims to stop the bike. The brake pads should be adjusted so they are 1 mm to 2 mm away from the rim when the brakes are not applied. Brake pads should be centered on the rim and “toed-in” so the rear portion of each brake pad is about 0.5
- 1.0 mm farther from the rim than the front portion of the brake pad.
35
Brake pad aligned with the rim surface Pad and rim should be parallel.
1- 2 mm
Do not ride the bicycle until the brakes are functioning properly. To test, apply the brakes while trying to push the bike forward to make sure they will stop the bicycle. Never ride a bicycle that is not functioning properly.
Do not lock up brakes. Sudden or excessive application of the front brake may pitch the rider over the handlebars, causing serious injury or death. When braking, always apply the rear brake first, then the front.

Disc Brakes
If fitted with a front disc brake, the components should already be attached. However, please check all connections before attempting to ride the bicycle. Secure tightly the 6 bolts that hold the disc to the front wheel hub and the 2 bolts that hold the brake mechanism to the fork. Insert the front wheel into the fork dropouts ensuring that the disc fits into the brake mecha­nism between the enclosed brake pads. Secure the front wheel to the bicycle by tightening the quick release mechanism and clamping the lever to the closed position. Please refer to sec­tion 6 for further instruction on quick release mechanisms.
Next, attach the cable to the brake lever by inserting the cable end into the cable end holder after the barrel adjuster and lock nut slots have been aligned with the cable end holder. After the cable is secured to the lever, rotate the barrel adjuster and lock nut so the slots no longer line up. Ensure the cable hous­ing seats appropriately into the end of the barrel adjuster and check for any kinks or damage.
Slide the exposed brake cable through the rotating rod located on the caliper body and seat the housing into the same stop. Insert the cable into the spring and spring boot.
Next, slide the cable through the cable anchor and pull all the slack out. Secure the cable in place by tightening the bolts that comprise the anchor assembly. Some disc brakes will have a centering devise while others are a free-floating mechanism. If your caliper body is equipped with centering bolts, apply the brake lever after the cable has been connected. While engaging the lever, tighten the centering bolts securely. This will center the caliper body on the disc.
DISC GETS HOT! Severe injury could result from contact with the hot disc! Mind your legs, as well as your hands.

Derailleur
Although the front and rear derailleurs are initially adjusted at the factory, you will need to inspect and readjust both before riding the bicycle.
Rear Derailleur Begin by shifting the rear shifter to largest number indicated, disconnect the cable from the rear derailleur cable anchor bolt, and place the chain on the smallest sprocket. Adjust the High limit screw so the guide pulley and the smallest sprocket are lined up vertically. Reconnect the cable, pull out any slack, and retighten the anchor bolt securely. Shift through the gears, making sure each gear achieved is done quietly and without hesitation. If necessary, use the barrel adjuster to fine tune each gear by turning it the direction you want the chain to go. For example, turning clockwise will loos­en the cable tension and move the chain away from the wheel, while turning counter-clockwise will tighten cable tension and direct the chain towards the wheel. Shift the rear shifter to the gear one and place the chain on the largest cog. Adjust the Low limit screw in quarter turn increments until the guide pulley and the largest cog are aligned vertically. Again, shift through each gear several times, checking that each gear is achieved smoothly. It may take several attempts before the rear derailleur and cable is adjusted properly.
Ensure all bolts are secured tightly and the chain does not fall off in either direction.

Front Derailleur
Shift both shifters to the smallest number indicated and place the chain on the corresponding cog and chainwheel. Discon­nect the front derailleur cable from the cable anchor bolt. Check the position of the front derailleur; it should be parallel with the outer chainwheel and clear the largest chainwheel by 1-3mm when fully engaged. With the chain on the smallest chainwheel in front and the largest cog in back, adjust the Low limit screw so the chain is centered in the front derailleur cage. Reconnect the cable, pull any slack out, and tighten the anchor bolt securely. Shift the front shifter to the largest chainwheel. If the chain does not go onto the largest chainwheel, turn the high limit screw in 1/4 turn increments counter-clockwise until the chain engages the largest chainwheel. If the chain falls off the largest chainwheel, and into the pedals, you will need to turn the High limit screw in 1/4 turn increments clockwise until the chain no longer falls off. Shift through every gear, using the barrel adjusters to fine tune each transition. The barrel adjuster for the front derailleur is located on the front shifter where the cable comes out of the shifter. Clockwise will loosen the cable tension and direct the chain closer to the frame while counter-clockwise will tighten the cable tension and direct the chain away from the frame.
Do not ride a bicycle that is not shifting proper­ly. Overlooking proper adjustments may cause irreparable damage to the bicycle and/or bodily injury. Never move the shifter while pedaling backward, nor pedal backwards after having moved the shifter. This could jam the chain and cause serious damage to the bicycle and/or rider.

Dual Suspension
Dual Suspension bikes (DS) are equipped with a front fork as well as a rear suspension generally located below the seat. The piston works in conjunction with a spring to allow the bike to rotate on a pivot point. Ensure all attaching hardware is secured and there is no lateral movement of the rear triangle. The amount of Rear Suspension travel can be adjusted by turning the adjusting plate. Clockwise will increase spring tension and decrease travel, while turning counter-clockwise will decrease spring tension and increase travel. There are many different types of suspension systems-too many to deal with individually in this manual.
There must be enough tension on the spring to hold the spring plate in place. Failure to do this may cause the mechanism to fail. Failure to maintain, check and properly adjust the suspension system may result in suspension malfunction, which can cause you to lose control and fall. Changing suspension adjustment can change the handling and braking characteristics of you bicycle. Never change suspension adjustment unless you are thoroughly familiar with the suspen­sion system, manufacturer’s instructions and recom­mendations, and always check for changes in the performance of your bicycle by taking a careful test ride in a hazard free area. If your bike has suspen­sion equipment, the increased speed you may develop also increases your risk. When braking, the front of a suspended bike dips. You could lose control and fall if your skill is not up to handling this system. Get to know how to handle your suspension system safely
before trying any downhill or very fast biking.

are the same. A shaft will pivot inside of two bushings secured in place with bolts. Pivots should be kept clean and free from grime and should be disassembled and re­greased at least once every riding season. Please note the drive side crank arm must be removed from the spin­dle before attempting to work on the pivot. Some models have two, small (2.5mm) Allen bolts on the underside of the bottom bracket shell. These must be removed before attempting to disassemble the pivot. After disassembling and cleaning, the shaft of the pivot assembly should be lightly coated with lithium-based grease, as well as the bushings and the threads of the attaching hardware. Please remember: Never use WD-40™ to grease com­ponents. It is a degreaser that will not provide required

Rear Fender
The rear fender is mounted at the seatstay brace. There are two ways in which to mount your rear fender. The first is the screw mounting system (see figure 3), and the second is the 10mm bolt and screw system (see figure 4). Identify the mounting system used on your bicycle and follow the given instructions for that particular type of mounting system.
1. Screw Mounting System
First remove the rear wheel. Place the fender assembly between the stays, making sure the fender bracket holes line up with those in the frame. Attach the fener by using two screws to directly mount the fender onto the frame. The mounts are located below the seat post and near the rear of the crank. Tighten all screws until snug.
2. 10mm Bolt and Screw System
First remove the rear wheel. Place the fender assembly between the stays, making sure the fender bracket holes line up with those in the frame. Attach the fender by using one screw to directly mount the fender onto the frame near the crank. Next, use the 10mm hex bolt and nut to attach the fender to the brace between the seat stays, near the seat post. Tighten all bolts and screws until snug.

Final Check
- After all adjustments have been made, shift through every gear several times at varying speeds. This will ensure all your adjustments are correct and will allow you to pinpoint any trouble areas. If you encounter any problems, refer to the appropriate section and make any necessary adjustments.
- Check the tire pressure and inflate each tube to the recommended psi as stated on the sidewall of the tire.
- Check that the kickstand operates smoothly and the kickstand bolt is secured tightly.
- Finally, examine the bicycle. Make sure all accessories are attached and all quick releases, nuts and bolts have been tightened securely.
- Correct maintenance of your bicycle will ensure many years of happy riding. Service your bicycle regularly by referring to the relevant sections of this manual, OR take it to a professional bicycle shop.
Remember: Always wear a helmet and obey all traffic laws.
Never inflate a tire beyond the maximum pressure marked on the tire’s sidewall. Exceeding the recommended pressure may blow the tire off the rim, which could cause damage to the bicycle and injury to the rider and bystanders.
Tighten both rear wheel axle nuts or the quick release mechanism securely. Failure to do this may cause the rear wheel to dislodge from the frame dropouts resulting in serious damage or injury.

Foreword: Assembling a bicycle is an important responsibility. Proper assembly not only gives the rider more enjoyment of the bicycle; it also offers an important measure of safety.
Getting Started
Open the carton from the top and remove the bicycle. Remove the straps and protective wrapping from the bicycle. Inspect the bicycle and all accessories and parts for possible shortages. It is recommended that the threads and all moving parts in the parts package be lubricated prior to installation. Do not discard packing materials until assembly is complete to insure that no required parts are accidentally discarded. Assemble your bicycle following the steps that pertain to your model.
Note: Your bicycle may be equipped with different style components than the ones illustrated.
Handlebars
Remove the protective cap from the stem wedge and loosen the stem bolt using the 6mm Allen key. Some models may use a 13mm hexagonal bolt instead of an Allen key bolt. Place the handlebar stem into the head tube, observing the minimum insertion mark on the handlebar stem and ensuring that all cables are free of tangles. Check that the fork and the handlebar are facing forward, and that they are properly aligned with the front wheel. Tighten the stem bolt. Rotate the handlebar to the desired position. Tighten stem cap bolt 1 (see picture) two turns, tighten stem cap bolt 2 two turns and so on. Repeat until handle bar is secure to the stem. See picture for a 4 or 6-bolt system. Also check that the stem binder bolts are tightened equally and securely.
The handlebar must be inserted so that the minimum insertion mark cannot be seen. WARNING: Over tightening the stem
bolt or headset assembly may cause damage to the bicycle and/ or injury to the rider.

Page 54
Seat
Loosen nut on the seat clamp and add 3 or 4 drops of oil onto the threads of the bolt. Place the smaller end of the seat post into the seat clamp until it stops with the bolt to the rear of the seat post. Thread the nut on the seat clamp loosely. Insert the larger end of the seat post into the seat tube of the bicycle frame observing the minimum insertion mark on the seat post. Position the top surface of the seat parallel with the ground. The serrations on the seat clamp must mesh completely with the seat frame serrations, push the front of the seat up and down to align the serrations. Securely tighten the seat clamp. Securely tighten the bolts on the seat post clamp. Turn the bicycle upside down and rest it on the seat and handlebars.
The seat pillar must be inserted so that the minimum insertion mark cannot be seen.
Pedals & Crank Set
Look for the letters “R” for right, and “L” for left, stamped on each pedal spindle. Start each pedal spindle by hand to avoid stripping the threads. Tighten with a 15mm narrow open ended wrench. Note that the right hand pedal attaches to the chainwheel side crank arm with a right-hand (clockwise) thread. The left pedal attaches to the other crank arm and has a left-hand (counter-clockwise) thread. It is very important that you check the crank set for correct adjustment and tightness before riding your bicycle. New cranks may become loose with initial use, refer to p. 83-86 for proper crank set adjustment and maintenance. Once the pedals have been attached, check that the crank arm rotates smoothly and that there is no lateral movement.

2. Place wheel into fork drop outs.
3. Install retaining washers with raised lip pointed towards the fork, and insert into the small hole of the fork blade. NOTE: Some bikes may have step retaining washers in place of the retaining washer (shown in dotted box). If so, install the step retaining washer, raised portion sliding in to the fork dropouts.
4. Install axle nut and tighten. Make sure the wheel is centered between the fork blades.
5. Spin the wheel to make sure that it is centered and clears the brake shoes. Tighten the brakes if necessary.
6. Turn the bicycle upright using the kickstand to support it.
It is very important to check the front wheel connection to the bicycle. Failure to properly tighten may cause the front wheel to dislodge.
Front Brake
Determine which type of brake your bike is equipped with and refer to the appropriate assembly instructions. For more information on brake adjustment and maintenance, refer to p. 77-80. A greater force is required to activate the rear brake due to longer cable length. It is advisable to mount the rear brake on the side of the stronger hand. It is important to become familiar with the use of hand brakes. When properly adjusted, hand brakes are an efficient braking system. Keep the rim and brake shoes clean and free from wax, lubricants and dirt at all times. Keep brakes properly adjusted and in good working
condition at all times.
Open the brake lever and place the nipple end of the short brake cable into the lever, then close the lever. Secure the ferrule against the lever using the cable adjusting barrel.

Cantilever Brakes - Utilizing a Link Wire
If fitted with cantilever type brakes, insert the brake cable into the link wire lead, and notch the cable end into the slot of the left brake arm. Loosen the anchor bolt on the right brake arm and slide the brake cable under the tabbed washer. Squeeze both brake arms together so the brake shoes hit the rim, pull all slack out of the brake cable, and tighten the anchor bolt. With the cable fitted, the straddle holder should sit 10-20mm above the reflector bracket. Adjust the brake shoes using a 10mm wrench so that they are parallel with the rim and are positioned 1-2mm away from the rim. Several adjustments may be necessary to achieve the correct brake position.

Cable

Caliper Arm
The length of the straddle cable, the height of the straddle hanger, and the brake pad-to-caliper arm position all have an effect on brak­ing power. Generally, the straddle cable bridge is set low and close to the tire for maximum braking force. The straddle cable should be high enough, however, to adequately clear the tire (and any debris that may stick to the tire) or to fit over the front reflector hanger. In the event of brake cable failure, the front reflector hanger would prevent the straddle cable from catching in the tire and locking up the front wheel. The straddle cable length (when adjustable) is set to transfer as much force to the brake pads as possible. For the most efficient transfer of force, the straddle cable and the line between the cantilever pivot and the cable anchor should form a right angle (90 degrees). If the force is not at a right angle, part of the force gets wasted in pulling on the brake post, which has no effect on braking.

U-Brakes
Begin by adjusting the pads of the U-brakes using a 10mm wrench. Make sure the pad is hitting the rim and not the tire. Ideally the front of the pad should hit the rim approximately 1mm before the rear pad.
Front U-Brake
Slide the brake cable and housing through the Housing Barrel and through the cable anchor bolt. Set the cable clearance of 1mm between the brake pads and the rim. Tighten the cable anchor bolt. All instructions shown are if you are looking at the bike from the front. For brake adjustments, use a 13mm box end wrench and a 5mm allen wrench. Loosen the 5mm allen bolt. For the drive side (left) of the bike turn the spring tension nut with a 13mm box end wrench counter-clockwise to increase tension on the spring. For the non-drive side (right), turn spring tension nut with a box end wrench clockwise to increase tension on the spring. When the desired tension is achieved hold the tension nut with the 13mm wrench and tighten the 5mm allen bolt. The tension on each side should be equal so that the brake arms move the same distance when the brake is activated.
Rear U-Brake
Option 1: Next, tighten the Cable Carrier to the brake cable approximately 20mm from the brake arms when they are closed against the rim. Attach the Straddle cable to the carrier. Hook cable end into the brake slot, pull excess straddle cable through the cable anchor and tighten the cable anchor. Continue with “For Both Options” below. Option 2: Place brake housing into the frame housing stops. Pull brake cable tightly and thread across through the opposite cable anchor bolt. Tight­en cable. Repeat for other side. Continue with “For Both Options” below. For Both Options: For brake adjustments, use a 13mm open end wrench and a 5mm allen wrench and loosen the 5mm allen bolt. For the drive side (right) of the bike turn the spring tension nut with a 13mm open end wrench counter clockwise to increase tension on the spring. For the non-drive side (left), turn the spring tension nut with a box end wrench clockwise to increase tension on the spring. When the desired tension is achieved, hold the tension nut with the 13mm wrench and tighten the 5mm allen bolt. The tension on each side should be equal so that the brake arms move the same distance when the brake is activated. PLEASE NOTE that some BMX frames have the U-Brake flipped and mounted below the seatstays. The direction to tension the springs will still be oriented to how the picture is oriented.

Figure 1
Figure 2
(Figure 2). Reassemble the lower cable roller assembly with the top plate. Be sure to pull the lower cable assembly up away from the hinge assembly. Make sure the cable roller is locked into place with the top plate.
5. Install the adjuster barrels into the proper slots.
6. Reattach the covering plate.
The rest of the assembly will follow the Rotor assembly procedures (page 56, beginning at the Upper Cable Section, Part 2).
Check your Brakes
Press each brake lever to make sure that there is no binding and that the brake pads press hard enough on the rims to stop the bike. The brake pads should be adjusted so they are 1mm to 2 mm away from the rim when the brakes are not applied. Brake pads should be centered on the rim and the rear portion of each brake pad should be about 0.5 - 1.0 mm farther from the rim than the front portion of the brake pad.
55
Do not ride the bicycle until the brakes are functioning properly. To test, apply the brakes while trying to push the bike forward to make sure they will stop the bicycle.
Page 63
Rotors
Some freestyle BMX bicycles come equipped with a detangler system that will allow the handlebar to spin 360-degrees without binding the cables. It is very important that this system is adjusted correctly. Installation should only be done by a qualified bicycle mechanic with the correct tools. Upper Cable
1. First connect the barrel end of the upper cable to the rear brake lever. Make sure the long cable casing is on top of the short cable casing; otherwise, the upper cable will have a twist in it.
2. Route the upper cable through the handlebars (below the crossbar) with the short cable casing on the same side as the rear brake lever.
3. Connect the upper cable to the upper plate by passing the football ends of the upper cable through the threaded holes in the upper plate and connecting them to the bearing.
4. Screw the adjusting barrels into the upper plate. Don’t tighten the locknuts at this time. Lower Cable
1. Slide the cable casing through the cable guide on the frame.
2. Connect the lower cable to the lower plate by passing the football ends of the lower cable through the threaded holes in the lower plate and connecting them to the bearing.
3. Screw the adjusting barrels into the lower plate. Don’t tighten the locknuts at this time.
4. Connect the lower cable to the rear brake. Don’t adjust the rear brake at this time. NOTE: Check to make sure all 11 cable casing ends on the upper and lower cables are seated correctly, and that the spring tension of the rear brake is pulling the bearing down.
Adjustment
1. Screw the cable adjusters on the rear brake lever and the upper cable splitter all the way in.
2. Screw the adjusting barrels in the upper plate in (or out)
to set the bearing for maximum travel. The bearing should
be as far down as it can go without resting on the lower plate or the adjusting barrels screwed into the lower plate.
3. Use the adjusting barrels that are screwed into the upper plate to make the bearing parallel to the upper plate. Use a 10mm wrench to tighten the locknut on the left adjusting barrel of the upper cable. Leave the right adjusting barrel loose.
4. Screw the lower cable adjusting barrel into (or out of) the lower plate until they are as close to the bearing as they can get without touching it.
5. Screw the cable adjuster on the upper cable splitter out until all slack is removed from the upper cable. Then screw the cable adjuster out one more turn to raise the bearing an additional 1mm away from the lower cable adjusting barrels. CAUTION: Don’t screw the cable adjuster on the upper cable splitter out more than 8mm. Use the cable adjuster on the rear brake lever if more adjustment is needed.
6. Check for bearing flop by placing the handlebars in the normal riding position, then quickly rotate the handlebars back and forth. Perform the following steps to eliminate bearing flop. NOTE: The bearing should never be allowed to rest on the lower plate or lower cable adjusting barrels. a) Screw the lower cable adjusting barrels out of (or into) the lower plate until all bearing flop is eliminated. b) Tighten the locknut of the right adjusting barrel on the lower cable. c) Rotate the handlebars 180 degrees and recheck for bearing flop. If there is any bearing flop, use the “loose” adjusting barrels on the upper and lower cable to remove it. d) Repeat steps (6a) and (6c) until the handlebars can be rotated 360 degrees without any bearing flop.
7. Finish adjusting the rear brakes.

WHEELS AND TIRES
Wheel Inspection
It is most important that wheels are kept in top condition. Properly maintaining your bicycle's wheels will help braking performance and stability when riding. Be aware of the following potential problems:
•Dirty or greasy rims: Caution: These can render your brakes ineffective. Do not clean them with oily or greasy materials. When cleaning, use a clean rag or wash with soapy water, rinse and air dry. Don't ride while they're wet. When lubricating your bicycle, don't get oil on the rim braking surfaces.
•Wheels not straight: Lift each wheel off the ground and spin them to see if they are crooked or out of true. If wheels are not straight, they will need to be adjusted. This is quite difficult and is best left to a bicycle specialist.
•Broken or loose spokes: Check that all spokes are tight and that none are missing or damaged. Caution: Such damage can result in severe instability and possibly an accident if not corrected. Again, spoke repairs are best handled by a specialist.
•Loose hub bearings: Lift each wheel off the ground and try to move the wheel from side to side. Caution: If there is movement between the axle and the hub, do not ride the bicycle. Adjustment is required.
•Axle nuts: Check that these are tight before each ride.
PART 5 - DETAILED MAINTENANCE
•Quick release: Check that these are set to the closed position and are properly tensioned before each ride.
Caution: Maintain the closed position and the correct adjustment. Failure to do so may result in serious injury.
66
Page 74
Tire Inspection
Tires must be maintained properly to ensure road holding and stability. Check the following areas:
Inflation: Ensure tires are inflated to the pressure indicated on the tire sidewalls. It is better to use a tire gauge and a hand pump than a service station pump. Caution: If inflating tires with a service station pump, take care that sudden over inflation does not cause tire to blow out.
Bead Seating: When inflating or refitting tire, make sure that the bead is properly seated in the rim.
Tread: Check that the tread shows no signs of excessive wear or flat spots, and that there are no cuts or other damage. Caution: Excessively worn or damaged tires should be replaced.
Valves: Make sure valve caps are fitted and that valves are free from dirt. A slow leak caused by the entry of the dirt can
lead to a flat tire, and possibly a dangerous situation.
Recommended Tire pressures:
The recommended pressure molded on the sidewall of your bicycle tires should match the following chart. Use this as a general guide.

Hub Bearing Adjustment
When checked, the hub bearings of either wheel will require adjustment if there is any more than slight side play.
1. Check to make sure neither locknut is loose.
2. To adjust, remove wheel from bicycle and loosen the locknut on one side of the hub while holding the bearing cone on the same side with a flat open end wrench.
3. Rotate the adjusting cone as needed to eliminate free play.
4. Re-tighten the locknut while holding the adjusting cone in position.
5. Re-check that the wheel can turn freely without excessive side play.
How To Fix a Flat Tire
If you need to repair a tire, follow these steps:
Push tire bead into the center
of the rim.
1. Remove the wheel from the bicycle.
2. Deflate the tire completely via the valve. Loosen the tire bead by pushing it inward all the way around.
3. Press one side of the tire bead up over the edge of the rim. Note: Use tire levers, not a screwdriver, otherwise you may damage the rim.
4. Remove the tube, leaving the tire on the rim.
5. Locate the leaks and patch using a tube repair kit, carefully following the instructions, or replace the tube. Note: Ensure that the replacement tube size matches the size stated on the tire sidewall and that the valve is the correct type for your bicycle.
68
Page 76
6. Match the position of the leak in the tube with the tire to locate the possible cause and mark the location on the tire.
7. Remove the tire completely and inspect for a nail, glass, etc. and remove if located. Also inspect the inside of the rim to ensure there are no protruding spokes, rust or other potential causes. Replace the rim tape which covers the spoke ends, if damaged.
8. Remount one side of the tire onto the rim.
69
Remove tire bead from the rim.
Pull tire back onto the rim.
9. Using a hand pump, inflate the tube just enough to give it some shape.
10. Place the valve stem through the hole in the rim and work the tube into the tire. Note: Do not let it twist.
11. Using your hands only, remount the other side of the tire by pushing the edge toward the center of the rim. Start on either side of the valve and work around the rim.
12. Before the tire is completely mounted, push the valve up into the rim to make sure the tire can sit squarely in position.
13. Fit the rest of the tire, rolling the last, most difficult part on using your thumbs. Note: Avoid using tire levers as these can easily puncture the tube or damage the tire.
14. Check that the tube is not caught between the rim and the tire bead at any point.
15. Using a hand pump, inflate the tube until the tire begins to take shape, and check that the tire bead is evenly seated all the way around the rim. When properly seated, fully inflate the tire to the pressure marked on the sidewall. Use a tire air pressure gauge to check.
16. Replace the wheel into the frame checking that all gears, brakes and quick release levers are properly adjusted.

HANDLEBARS AND STEM
Handlebar Stem
The handlebar stem fits into the steering column and is held firm by the action of a binder bolt and expander wedge which, when tightened, binds with the inside of the fork steerer tube. When removing the stem, loosen the stem bolt two or three turns, then give it a tap to loosen the wedge inside. Lubricate by first wiping off any old grease and grime, then applying a thin film of grease to the part, including the wedge, that will be inserted into the frame. The height of the handlebar can be adjusted to suit your comfort preference. If the stem is removed from the steering column, you will notice a mark about 65mm up from the bottom with the words “max. height” or “minimum insertion".

The exact positioning of the handlebar is a matter of personal comfort. For MTB bicycles, the bar should be approximately horizontal, with the ends pointing back and slightly up. On BMX bicycles, the handlebar should remain in an approximately upright position but can be angled back or forward slightly for comfort. On MTB and racing style bicycles, the handlebar is usually tightened in the stem by a single allen key bolt or hexagonal bolt. On BMX style bicycles there may be four clamping bolts.
Please note that if you need to replace the fork on your bicycle at any time, please consult a qualified bicycle technician.
Never ride unless the handlebar clamping mechanism has been securely tightened.

2. Rotate assembly until cable exits beneath brake lever with adequate clearance for brake lever movement.
3. Firmly tighten recessed clamp screw. Installation torque should be 20 in.-lbs.
4. Slide the two 7/8” plastic washers over handlebar. The washers prevent the grip from interfering with Grip Shift™ rotation.
5. Slide handlebar grip over handlebar. Thread the cable inner wire through cable housings and frame, and attach to derailleur. Make sure that the cable is in the V groove at the derailleur attachment bolt. If trimming the cable housing is necessary, be sure to replace the housing end cap.
6. Adjust indexing.
7. Slide rear Grip Shift™ over right side of handlebar and repeat steps 2 - 6.
8. Actuate front and rear brake levers to be certain of proper operation. If Grip Shift™ interferes with brake lever movement, rotate brake lever or Grip Shift™. Check for proper brake lever operation again.

Cables and Cable Housing
Cables and housing are one of the most over­looked parts on the bicycle. The first indication that your cables and housing need to be replaced is an increased amount of pressure needed to operate the brakes or shifters. Before every ride, check that there are no kinks or frays in the cables and housing. Also check that the housing is seated properly into each cable stop of the bicycle. It is recommended that the cables and housing are replaced at least every riding season to prolong the life of your bike.
Do not ride a bicycle that is not operating properly.

HEADSET
Inspection
The headset bearing adjustment should be checked every month. This is important as it is the headset which locks the fork into the frame, and if loose, can cause damage or result in an accident. While standing over the frame top tube with both feet on the ground, apply the front brake firmly and rock the bicycle back and forth; if you detect any looseness in the headset, it will need adjustment. Check that the headset is not over tight by slowly rotating the fork to the right and left. If the fork tends to stick or bind at any point, the bearings are too tight.

Page 83
Adjustment
As mentioned in Part 2, the seat can be adjusted in height, angle and distance from the handlebars to suit the individual rider. Saddle angle is a matter of personal preference but the most comfortable position will usually be found when the top of the seat is almost parallel to the ground, or slightly raised at the front.
The saddle can also be adjusted by sliding it forward or back along the mounting rails to obtain the most comfortable reach to the handlebars. When fitting, position the seat post into the clamp under the seat and place it in the frame without tightening. Adjust it to the desired angle and position, and tighten the clamping mechanism.
There are two types of seat clamps commonly in use. The most common employs a steel clamp with hexagonal nuts on either side to tighten. The other type, known as a micro-adjustable clamp, uses a single vertically mounted Allen head fixing bolt to tighten. After fixing the seat to the desired position on the post, adjust the height to the required level and tighten the binder bolt.
Note that the type of binder bolt may be either a hexagonal bolt, an Allen head bolt or a quick release mechanism. The operation of a seat post quick release mechanism is the same as for quick release hubs. Refer to p. 27. Test the security by grasping the seat and trying to turn it sideways. If it moves, you will need to further tighten the binder bolt.
Note: Remember that the minimum insertion mark must remain inside the frame assembly.

BRAKES
The correct adjustment and operation of your bicycle's brakes is extremely important for safe operation. Brakes should be checked for effective operation before every ride. Frequent checking of adjustment is necessary as the control cables will stretch and the brake pads will become worn with use.
Never ride a bicycle unless the brakes are functioning properly.
There are two types of hand operated bicycle brakes in common use: sidepull calipers and cantilever calipers. Both utilize a handlebar mounted lever which controls a cable to operate the brake. Sidepull brakes are mounted to the frame or fork via a single pivot point. Cantilever brakes use two brake pivot arms, each mounted on separate pivots on either side of the frame/fork.
Inspection
Brake levers should be checked for tightness at least every three months. They should be set in a comfortable position within easy

reach of the rider's hands, and must not be able to move on the handlebar. Some brake levers make use of a reach adjustment screw, which can be altered to the distance between the handlebar grip and the lever, as required. The brake pads should be checked for correct positioning and tightness before every ride, and the various bolts and nuts at least every three months. Squeeze each brake lever to make sure they operate freely and that the brake pads press hard enough on the rims to stop the bike. There should be about 1mm - 2mm clearance between each pad and the rim when the brakes are not applied. The brake pads must be properly centered for maximum contact with the rim. Replace the brake pads if they are over worn so that the grooves or pattern cannot be seen. The brake cable wires should be checked for kinks, rust, broken strands or frayed ends. The outer casing should also be checked for kinks, stretched coils and other damage. If the cables are damaged, they should be replaced.

Some brakes have a quick release mechanism to allow easier wheel removal. Whenever you adjust the brakes, make sure the quick release mechanism is in the closed position.
Never ride unless the quick release is firmly locked in the closed position.

The brake lever and brake caliper pivot points should be oiled with 2-3 drops of light oil at least every three months to ensure smooth operation and to reduce wear. Cables should be greased along their entire length, after removing them from their casings, at least every six months. Always grease new cables before fitting.
Adjustment - Sidepull Calipers
Minor brake adjustment can be made via the cable adjusting bar­rel, usually located at the upper cable arm. To adjust, squeeze the brake pads against the rim, loosen the lock nut and turn the adjuster Brake pad clearance should be a maximum 2mm from the rim. When correct, re-tighten the lock nut. If the pads cannot be set close enough to the rim in this manner, you may have to adjust the cable length. Screw the barrel adjuster 3/4 of the way in, squeeze the pads against the rim, undo the cable anchor bolt and pull the cable through with pliers. Re-tighten the cable anchor bolt and apply full force to the brake lever to test, then fine tune using the barrel adjuster. If one pad is closer to the rim than the other, loosen the fixing nut at the back of the brake, apply the brake to hold it centered, and re-tighten the fixing nut.
Ensure the Brake fixing nut is secured tightly. Failure to do this may cause the Brake assembly to dislodge from the fork.

Some brakes have a special mechanism which enables you to set the clearance on either side of the rim using a screwdriver. Brake pads should finally be adjusted so that the leading edge of the pad makes first contact with the rim. Some brakes have special curved washers to allow this, but on less complex models it will be necessary to apply a little force to the pad and its mounting.
Adjustment - Cantilever Calipers
Minor brake adjustment can be made via the barrel cable adjusters which are located on each brake lever. To adjust, squeeze the brake pads against the rim, loosen the lock nut, and turn the adjuster to pull the brake pads closer to, or spread them away from the rim as required. Brake pad clearance should be a maximum 2mm from the rim. When correct, re-tighten the lock nut. If the pads cannot be set close enough to the rim in this manner, you may have to adjust either the length of the straddle cable or the length of the brake cable.
If the brakes use a separate brake cable and straddle cable, adjust the straddle length by first screwing the barrel adjuster 3/4 of the way in, then loosening the straddle cable fixing bolt, then pulling or pushing the cable through the fixing bolt to adjust the length, and finally re-tightening the fixing bolt.
Check that the straddle bridge is in the middle of the cable to ensure even brake pad contact. Apply full force to the brake lever to test, then fine tune using the barrel adjuster.
To adjust the brake cable length, loosen the brake cable fixing bolt on the cable straddle bridge, adjust the length until the brake shoes are the correct distance from the rim, then re-tighten and test.

Tread Tread Worn Off
On some newer type cantilever brakes, the main brake cable continues through the central cable carrier to an anchor bolt on one of the brake arms. A shorter link cable reaches from the carrier and the hook on the other brake arm. Adjustment of the cable length is made after loosening the anchor bolt on the brake arm.

Adjust the brake pad position so that it is parallel to the wheel rim and so that the leading edge makes first contact. To do this, fit an Allen key into the brake pad holding bolt, loosen the fixing nut and adjust. Move the brake pad along its mounting post to alter the dis­tance from the rim, and move the curved adjustment washer to alter the angle of the pad.
On some models there is a spring-force adjustment screw on the brake arm which allows further fine tuning of the brake shoe position.
Bicycles with cantilever brakes must be fitted with safety devices to prevent a possible accident in the event of the brake control cable or the straddle bridge becoming loose or breaking while rid­ing. These are usually the reflector brackets, and must be fitted in the front and rear. The bracket will prevent the straddle cable from interfering with the wheel should the cable become disconnected from the control cable. If the reflector brackets are not fitted in this position, then alternative emergency cable safety stops must still be fit­ted.

DRIVETRAIN
The drivetrain of a bicycle refers to all parts that transmit power to the rear wheel including the pedals, chain, chainwheel, crank set, and freewheel.
PEDALS
Pedals are available in a variety of shapes, sizes and materials, and each are designed with a particular purpose in mind. Some pedals can be fitted with toe clips and straps. These help to keep the feet correctly positioned and allow the rider to exert pulling force, as well as downward pressure, on the pedals. Use of toe clips with straps requires practice to acquire the necessary skill to operate them safely.
Inspection
Pedals should be inspected every month, taking note of the follow ing areas:
- Check correct tightness into the crank arms. If pedals are allowed to become loose, they will not only be dangerous but will also cause irreparable damage to the cranks.
- Check that pedal bearings are properly adjusted. Move the pedals up and down, and right to left, and also rotate them by hand. If you detect any looseness or roughness in the pedal bearings then adjustment, lubrication or replacement is required.
- Ensure that the front and rear pedal reflectors are clean and securely fitted.
- Also ensure that the toe clips, if fitted, are securely tightened to the pedals.
Never ride with loose pedals.
81
Page 89
Lubrication and Adjustment
Many pedals cannot be disassembled to allow access to the internal bearings and axle. However, it is usually possible to inject a little oil onto the inside bearings, and this should be done every six months. If the pedal is the type that can be fully disassembled, then the bearings should be removed, cleaned and greased every six to twelve months. Because of the wide variety of pedal types and their internal complexity, disassembly procedures are beyond the scope of this manual and further assistance should be sought from a specialist.
Never ride in traffic with fully tightened toe straps.
Pedal with toe clip and strap attached
Attachment
Note: The right and left pedals of a bicycle each have a different thread and are not interchangeable.
Never force a pedal into the incorrect crank arm. The right pedal, which attaches to the chainwheel side, is marked 'R' on the end of the axle, and screws in with a clock­wise thread. The left pedal, which attaches to the other crank arm, is marked 'L' on the axle, and screws in with a coun­ter-clockwise thread. Insert the correct pedal into the crank arm and begin to turn the thread with your fingers only. When the axle is screwed all the way in, securely tighten using a 15mm wrench. If removing a pedal, remember that the right pedal axle must be turned counter clockwise, i.e. the reverse of when fitting. If replacing the original pedals with a new set, make sure the size and the axle thread is compatible with the cranks on your bicycle. Bicycles use one of two types of cranks and these use different axle threads. Your bike may be equipped with cranks that are a one piece design with no separate axle. These operate with pedals that have a 1/2"(12.7mm) thread. Bikes equipped with three piece crank sets with a separate axle, left crank and right crank, use a slightly larger 9/16"(14mm) thread.
Note: Never try and force a pedal with the wrong thread size into a bicycle crank.

CRANK SET
The crank set refers to the bottom bracket axle and bearings, the crank arms, and chainrings. Your bike may be fitted with either a one piece crank, where the crank arms and bottom bracket are a single component, or cotterless cranks, where the crank arms bolt onto the bottom bracket axle without using old fashioned type cotterpins. The one piece system is simpler and requires less maintenance, while the cotterless system requires a little extra care.
Never ride your bike if the cotterless cranks are loose. This may be dangerous and will damage the crank arms beyond repair.
Inspection
The crank set should be checked for correct adjustment and tightness every month. Cotterless crank axle nuts must be kept tight, and the bottom bracket bearings must be properly adjusted. Remove the chain and try to move the cranks from side to side with your hands. The cranks should not move on the axle, and there should be only very slight movement in the bottom bracket. Next, spin the cranks. If they don't spin freely without grinding noise, then adjustment or lubrication will be needed. Also check that there are no broken teeth on the chainrings, and wipe off excess dirt and grease that may have built up on them.

CHAIN
Inspection
The chain must be kept clean, rust free and frequently lubricated in order to extend its life as long as possible. It will require replacement if it stretches, breaks, or causes inefficient gear shifting. Make sure that there are no stiff links, they must all move freely.
87
10 mm
Straightedge
Lubrication
The chain should be lubricated with light oil at least every month, or after use in wet, muddy, or dusty conditions. Take care to wipe off excess oil, and not to get oil on the tires or rim braking surfaces.
Adjustment and Replacement
On derailleur geared bicycles the rear derailleur automatically tensions the chain. To adjust the chain on single speed freewheel, coaster hub braked or 3-speed hub geared bicycles:
1. Loosen the rear axle nuts (and coaster brake arm clip if fitted) and move the wheel forward to loosen, or backward to tighten, in the frame.
2. When correctly adjusted, the chain should have approximately 10mm of vertical movement when checked in the center between the chainwheel and rear sprocket. Center the wheel in the frame and re-tighten the axle nuts after any adjustment. Bicycles which have a single speed freewheel, coaster hub brake or 3-speed hub, generally use a wider type chain than derailleur geared bicycles. These chains can be disconnected by way of a special U-shape joining link, that can be pried off of the master link with a screwdriver. To replace, feed the chain around the chainwheel and rear sprocket, fit the master link into the rollers into each end of the chain, position the master link side plate, and slip on the U-shaped snap-on plate. Make sure the open end of the U-shaped plate is trailing as the link approaches the chainwheel when pedaling forward.
Page 95
Chain Rivet Tool
Derailleur geared bicycles use narrower chains and require a special tool to fit and remove chain links, or to change the length. To remove, fit the rivet tool so that the punch pin is centered over any one of the chain rivets. Push the rivet almost all the way out, then back out the punch and remove the tool. Holding the chain on both sides of the punched rivet, bend it slightly to release link from the rivet. To install, feed chain around chainwheel, rear sprocket and derailleur cage with rivet facing away from the bicycle. Bring the two ends together within the special tool and punch the rivet into place. Be sure not to push rivet too far through side plate.
FREEWHEEL Inspection
Like the chain, the freewheel must be kept clean and well lubricated. If the chain has become worn and needs replacing, then it is likely that the freewheel will also have become worn and should also be replaced. Take the chain off the freewheel and rotate it with your hand. If you hear a grinding noise or the freewheel stops suddenly after spinning it, it may need adjustment or replacement. Such action is beyond the scope of this manual and you should consult a specialist.
88
Page 96

Lubrication
Remove any accumulated dirt from the freewheel with a brush and a degreaser. Disassembly of the freewheel is a complicated procedure requiring special tools, and should be left to a specialist. Apply oil to the freewheel whenever you lubricate the chain, taking care to wipe off any excess.
COASTER HUB
Many BMX style and other children's bicycles are fitted with a coaster hub brake in the rear wheel. This type of brake offers the advantages of reliability and easy operation. The brake is operated by applying back pedal pressure and allows the rider to 'coast' without pedaling, if desired. There are several models of coaster hubs available, and the internal mechanisms are very complex. They require infrequent attention as far as lubrica­tion, adjustment or replacement of internal parts; if needed, this should be left to a specialist. Keep the coaster hub sprocket clean and oil it along with the chain.
Make sure the brake arm is correctly attached to the chainstay with the brake arm clip. The brake will not operate otherwise.

Page 97
DERAILLEUR SYSTEMS
The derailleur system includes the front and rear derailleurs, the shift levers, and the derailleur control cables, all of which must function correctly for smooth gear shifting to occur. There are several different types of derailleur systems but all operate using similar principles. Your new bicycle may be fitted with a standard 'friction' type system where you will need to feel each gear shift into position. It may be fitted with an ‘index’ system (e.g. SIS) which links each different gear position to a positive click mechanism in the shifter, and makes shifting very simple and precise. A further development of SIS is the fully integrated system (e.g. STI) where the shift lever and brake lever mechanisms form an integrated unit with the system allowing both gear shifting and braking to occur at the same time.
Inspection
Pre-stretch the derailleur cables to remove slack
Stretch
The operation of the derailleur system should be checked at least every month. Check the operation of the rear derailleur first, then the front. The rear derailleur should shift the chain cleanly from one cog to the next without hesitation. On SIS equipped bicycles, each notched position in the shifter must equate to a new gear position. After shifting, the rear derailleur should not rub on the chain. The derailleur should never cause the chain to fall off the inner or outer freewheel cogs. The front derailleur should also shift the chain cleanly and without hesitation between each chainring. If your bicycle is equipped with front SIS, then each click or stop in the shifter should equate exactly to a new gear position. When the chain has been positioned onto a new chainring, it should not rub on the front derailleur. The chain should not fall off a chainring at any time. Derailleur control cables are a critical component that must be well maintained for accurate shifting performance. Check them for any sign of rust, fraying, kinks, broken strands and any damage to the cable housing. If you find any problems, the cables may need replacing before you ride.

The Low limit screw determines how far the rear derailleur will travel toward the wheel of the bicycle, while the High limit screw determines how far the cage will travel toward the frame.
1. Shift the rear shifter to the largest number indicated, disconnect the rear derailleur cable from the cable anchor bolt and place the chain on the smallest sprocket.
2. Adjust the High limit screw so the chain and the smallest sprocket are lined up vertically. Remove any slack in the cable by pulling it taut, then re-connect the cable and tighten the cable anchor bolt securely.
3. Shift up through the gears making sure that each gear is achieved quietly and without hesitation. If noise occurs, use the barrel adjuster to fine-tune the cable tension. Turning the barrel adjuster clockwise will decrease cable tension and allow the derailleur cage to move farther away from the bicycle in small increments. Turning counter-clockwise will increase cable tension and bring the cage closer to the bicycle. This will micro-adjust the positioning of the derailleur cage in relation to the freewheel. Simply put; turn the barrel adjuster the direction you want the chain to go.
4. Shift the chain onto the largest sprocket; adjust the low limit screw so the chain and the largest cog are lined up vertically. If you are unable to get the chain to the largest cog, turning the Low limit screw counter-clockwise will enable the chain to move towards the wheel.
5. Shift through the gears ensuring each gear is achieved quietly and without hesitation. NOTE: It may take several adjustments to achieve the desired positioning. Please refer to the troubleshooting section for more assistance.

1. Shift the rear shifter to the smallest number indicated, then shift the front shifter to the smallest number indicated. Disconnect the front derailleur cable from the cable anchor bolt and place the chain on the smallest chainwheel.
2. Make sure the front derailleur cage is parallel with the outer chainwheel on the crankset. There must be a 1-3mm gap between the bottom of the derailleur cage and the top of the outer chainwheel teeth to ensure the derailleur will clear the chainwheel when shifting.
3. Adjust the Low limit screw so the chain is centered in the middle of derailleur cage. Pull all slack out of the cable by pulling it taut, then reconnect the cable and tighten the cable anchor bolt securely.
4. Shift the front shifter into the largest gear and pedal the bike so the chain jumps to the largest chainwheel. If the chain does not shift onto the largest chainwheel, you will need to turn the High limit screw counter-clockwise until the chain moves to the largest chainwheel. If the chain falls into the pedals, the High limit screw has been turned too far. You will need to readjust the High screw clockwise in 1/4 turn increments until the chain no longer falls off.
5. Shift through each gear ensuring all are achieved quietly and without hesitation.
6. The barrel adjuster for the front derailleur is located on the shift mechanism. Turning clockwise will decrease cable tension and allow the front derailleur cage to move away from the bike, while turning counter-clockwise will increase tension and bring the cage closer to the bike. If you are experiencing problems shifting between gears, use the barrel adjuster to fine-tune the cable tension.
NOTE: It may take several adjustments to achieve the desired positioning.

QUICK RELEASE LEVERS
It is important to check the quick release levers before every ride to ensure all connections are made properly and securely. Periodically, disassemble the mechanism from the bicycle and inspect for any wear or damage and replace if necessary. When reinstalling, it is very important to ensure the connections are made properly. Please refer to page 29-30 for the appropriate assembly instructions.
REFLECTORS
Your bicycle is supplied with one front (white), one rear (red), two wheel (white), and two pedal (orange) reflectors. These are an important safety and legal requirement, and should remain securely fitted and in good, clean conditions at all times. Periodically, inspect all reflectors, brackets and mounting hardware for signs of wear or damage. Replace immediately if damage is found. Please see pages 12-13 for more information.
