GENERAL WARNING:
Like any sport, bicycling involves risk of injury and damage. By choosing to ride a bicycle, you assume
the responsibility for that risk, so you need to know — and to practice — the rules of safe and responsible
riding and of proper use and maintenance. Proper use and maintenance of your bicycle reduces risk of
injury.
!
This Manual contains many “Warnings” and “Cautions” concerning the consequences of failure to
maintain or inspect your bicycle and of failure to follow safe cycling practices.
!
• The combination of the safety alert symbol and the word WARNING indicates a potentially
hazardous situation which, if not avoided, could result in serious injury or death.
!
• The combination of the safety alert symbol and the word CAUTION indicates a potentially
hazardous situation which, if not avoided, may result in minor or moderate injury, or is an alert against
unsafe practices.
!
• The word CAUTION used without the safety alert symbol indicates a situation which, if not avoided,
could result in serious damage to the bicycle or the voiding of your warranty.
!
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 always repeat the warning of possible injury or death.
!
Because it is impossible to anticipate every situation or condition which can occur while riding, this
Manual makes no representation about the safe use of the bicycle under all conditions. There are risks
associated with the use of any bicycle which cannot be predicted or avoided, and which are the sole
responsibility of the rider.
!
IMPORTANT:
This manual contains important safety, performance and service information. Read it before you take
the first ride on your new bicycle, and keep it for reference.
!
Additional safety, performance and service information for specific components such as suspension or
pedals on your bicycle, or for accessories such as helmets or lights that you purchase, may also be available.
Make sure that your dealer has given you all the manufacturers’ literature that was included with your bicycle
or accessories.
!
If you have any questions or do not understand something, take responsibility for your safety and
consult with your dealer or the bicycle’s manufacturer.

A special note for parents:
As a parent or guardian, you are responsible for the activities and safety of your minor child, and that
includes making sure that the bicycle is properly fitted to the child; that it is in good repair and safe operating
condition; that you and your child have learned and understand the safe operation of the bicycle; and 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, as well as review its warnings and the bicycle’s functions and operating procedures with
your child, before letting your child ride the bicycle.
WARNING: Make sure that your child always wears an approved bicycle helmet when riding;
but also make sure that your child understands that a bicycle helmet is for bicycling only, and must
be removed when not riding. A helmet must not be worn while playing, in play areas, on playground
equipment, while climbing trees, or at any time while not riding a bicycle. Failure to follow this
warning could result in serious injury or death.

1. First
!
NOTE: We strongly urge you to read this Manual in its entirety before your first ride. At the very least, read
and make sure that you understand each point in this section, and refer to the cited sections on any issue
which you don’t completely understand. Please note that not all bicycles have all of the features described in
this Manual. Ask your dealer to point out the features of your bicycle.
A. Bike fi t
!
1. Is your bike the right size? To check, see Section 3.A. If your bicycle is too large or too small for you, you
may lose control and fall. If your new bike is not the right size, ask your dealer to exchange it before you ride
it.
2. Is the saddle at the right height? To check, see Section 3.B. If you adjust your saddle height, follow the
Minimum Insertion instructions in Section 3.B.
3. Are saddle and seatpost securely clamped? A correctly tightened saddle will allow no saddle movement in
any direction. See Section 3.B.
4. Are the stem and handlebars at the right height for you? If not, see Section 3.C.
5. Can you comfortably operate the brakes? If not, you may be able to adjust their angle and reach. See
Section 3.D and 3.E.
6. Do you fully understand how to operate your new bicycle? If not, before your first ride, have your dealer
explain any functions or features which you do not understand.
!
B. Safety first
1. Always wear an approved helmet when riding your bike, and follow the helmet manufacturer’s instructions
for fit, use and care.
2. Do you have all the other required and recommended safety equipment? See Section 2. It’s your
responsibility to familiarize yourself with the laws of the areas where you ride, and to comply with all
applicable laws.
3. Do you know how to correctly operate your wheel quick releases? Check Section 4.A.1 to make sure.
Riding with an improperly adjusted wheel quick release can cause the wheel to wobble or disengage from
the bicycle, and cause serious injury or death.
4. If your bike has toeclips and straps or clipless (“step-in”) pedals, make sure you know how they work (see
Section 4.E). These pedals require special techniques and skills. Follow the pedal manufacturer’s
instructions for use, adjustment and care.
5. Do you have “toe overlap”? On smaller framed bicycles your toe or toeclip may be able to contact the front
wheel when a pedal is all the way forward and the wheel is turned. Read Section 4.E. to check whether you
have toeclip overlap.
6. Does your bike have suspension? If so, check Section 4.F. Suspension can change the way a bicycle
performs. Follow the suspension manufacturer’s instructions for use, adjustment and care.
6
C. Mechanical Safety Check
Routinely check the condition of your bicycle before every ride.
Nuts, bolts screws & other fasteners: Because manufacturers use a wide variety of fastener sizes and
shapes made in a variety of materials, often differing by model and component, it is not possible for this
Manual to specify correct torque (tightening force) for the fasteners on your bicycle. We can tell you the
importance of correct torque, but not the specific torque required for each fastener on your bicycle. To
correctly torque a fastener, a torque wrench must be used. A professional bicycle mechanic with a torque
wrench should torque the fasteners on you bicycle. If you choose to work on your own bicycle you must get
correct tightening torque specifications from the bicycle or component manufacturer or from your dealer. If
you need to make an adjustment at home or in the field, we urge you to exercise care, and to have the
fasteners you worked on checked by your dealer as soon as possible.
!
WARNING: Correct tightening force on fasteners –nuts, bolts, screws– on your bicycle is
important. Too little force, and the fastener may not hold securely. Too much force, and the fastener
can strip threads, stretch, deform or break. Either way, incorrect tightening force can result in
component failure, which can cause you to loose control and fall.
!
Make sure nothing is loose. Lift the front wheel off the ground by two or three inches, then let it bounce
on the ground. Anything sound, feel or look loose? Do a visual and tactile inspection of the whole bike.
Any loose parts or accessories? If so, secure them. If you’re not sure, ask someone with experience to
check.
!
Tires & Wheels: Make sure tires are correctly inflated (see Section 4.G.1). Check by putting one hand on
the saddle, one on the intersection of the handlebars and stem, then bouncing your weight on the bike while
looking at tire deflection. Compare what you see with how it looks when you know the tires are correctly
inflated; and adjust if necessary.
!
Tires in good shape? Spin each wheel slowly and look for cuts in the tread and sidewall. Replace damaged
tires before riding the bike.
Wheels true? Spin each wheel and check for brake clearance and side-to-side wobble. If a wheel wobbles
side to side even slightly, or rubs against or hits the brake pads, take the bike to a qualified bike shop to
have the wheel trued.
!
CAUTION: Wheels must be true for the brakes to work effectively. Wheel truing is a skill
which requires special tools and experience. Do not attempt to true a wheel unless you have the
knowledge, experience and tools needed to do the job correctly.
!
Wheel rims clean and undamaged? Make sure the rims are clean and undamaged along the braking surface,
and check for excess rim wear.
Brakes: Check the brakes for proper operation (see Sections 4.C). Squeeze the brake levers. Are the brake
quick-releases closed? All control cables seated and securely engaged? Do the brake pads contact the
wheel rim squarely and make full contact with the rim? Do the brake pads touch the wheel rim within an inch
of brake lever movement? Can you apply full braking force at the levers without having them touch the
handlebar? If not, your brakes need adjustment. Do not ride the bike until the brakes are properly adjusted
by a professional bicycle mechanic.
Quick Releases: Make sure the front wheel, rear wheel and seat post quick releases are properly adjusted
and in the locked position. See Section 4.A and 4.B.
7
Handlebar and saddle alignment: Make sure the saddle and handlebar stem are parallel to the bike’s
center line and clamped tight enough so that you can’t twist them out of alignment. See Sections 3.B and
3.C.
Handlebar ends: Make sure the handlebar grips are secure and in good condition. If not, have your
dealer replace them. Make sure the handlebar ends and extensions are plugged. If not, have your dealer
plug them before you ride. If the handlebars have bar end extensions, make sure they are clamped tight
enough so you can’t twist them.
!
WARNING: Loose or damaged handlebar grips or extensions can cause you to lose control and
fall. Unplugged handlebars or extensions can cut you and cause serious injury in an otherwise
minor accident.
!
VERY IMPORTANT SAFETY NOTE:
Please also read and become thoroughly familiar with the important information on the lifespan of
your bicycle and its components in Appendix A on Page 33.
D. First ride
When you buckle on your helmet and go for your first familiarization ride on your new bicycle, be sure to
pick a controlled environment, away from cars, other cyclists, obstacles or other hazards. Ride to become
familiar with the controls, features and performance of your new bike.
Familiarize yourself with the braking action of the bike (see Section 4.C). Test the brakes at slow speed,
putting your weight toward the rear and gently applying the brakes, rear brake first. Sudden or excessive
application of the front brake could pitch you over the handlebars. Applying brakes too hard can lock up a
wheel, which could cause you to lose control and fall. Skidding is an example of what can happen when a
wheel locks up.
If your bicycle has toeclips or clipless pedals, practice getting in and out of the pedals. See paragraph B.4
above and Section 4.E.4.
If your bike has suspension, familiarize yourself with how the suspension responds to brake application
and rider weight shifts. See paragraph B.6 above and Section 4.F.
Practice shifting the gears (see Section 4.D). Remember to never move the shifter while pedaling
backward, nor pedal backwards immediately after having moved the shifter. This could jam the chain and
cause serious damage to the bicycle.
Check out the handling and response of the bike; and check the comfort.
If you have any questions, or if you feel anything about the bike is not as it should be, consult your
dealer before your next ride.

2. Safety
!
A. The Basics
!
WARNING: Many provinces or territories require specific safety devices. It is your
responsibility to familiarize yourself with the laws of the provinces or territories where you ride
and to comply with all applicable laws, including properly equipping yourself and your bike as
the law requires.
Observe all local bicycle laws and regulations. Observe regulations about bicycle lighting,
licensing of bicycles, riding on sidewalks, laws regulating bike path and trail use, helmet laws, child
carrier laws, special bicycle traffic laws. It’s your responsibility to know and obey the laws.
!
1. Always wear a cycling helmet which meets the latest certification standards and is
appropriate for the type of riding you do. Always follow the helmet manufacturer’s
instructions for fit, use and care of your helmet. Most serious bicycle injuries involve
head injuries which might have been avoided if the rider had worn an appropriate
helmet.
!
WARNING: Failure to wear a helmet when riding may result in serious injury
or death.
!
2. Always do the Mechanical Safety Check (Section 1.C) before you get on a bike.
Fig.1
3. Be thoroughly familiar with the controls of your bicycle: brakes (Section 4.C.); pedals (Section 4.E.);
shifting (Section 4.D.)
4. Be careful to keep body parts and other objects away from the sharp teeth of chainrings, the moving chain,
the turning pedals and cranks, and the spinning wheels of your bicycle.
5. Always wear:
• Shoes that will stay on your feet and will grip the pedals. Make sure that shoe laces cannot get into
moving parts, and never ride barefoot or in sandals.
• Bright, visible clothing that is not so loose that it can be tangled in the bicycle or snagged by objects at
the side of the road or trail.
• Protective eyewear, to protect against airborne dirt, dust and bugs — tinted when the sun is bright, clear
when it’s not.
!
6. Don’t jump with your bike. Jumping a bike, particularly a BMX or mountain bike, can be fun; but it can put
huge and unpredictable stress on the bicycle and its components. Riders who insist on jumping their bikes
risk serious damage, to their bicycles as well as to themselves. Before you attempt to jump, do stunt riding
or race with your bike, read and understand Section 2.F.
7. Ride at a speed appropriate for conditions. Increased speed means higher risk.
9
B. Riding Safety
!
1. You are sharing the road or the path with others — motorists, pedestrians and other cyclists. Respect
their rights.
2. Ride defensively. Always assume that others do not see you.
3. Look ahead, and be ready to avoid:
• Vehicles slowing or turning, entering the road or your lane ahead of you, or coming up behind you.
• Parked car doors opening.
• Pedestrians stepping out.
• Children or pets playing near the road.
• Pot holes, sewer grating, railroad tracks, expansion joints, road or sidewalk construction, debris and
other obstructions that could cause you to swerve into traffic, catch your wheel or cause you to have an
accident.
• The many other hazards and distractions which can occur on a bicycle ride.
4. Ride in designated bike lanes, on designated bike paths or as close to the edge of the road as possible, in
the direction of traffic flow or as directed by local governing laws.
5. Stop at stop signs and traffic lights; slow down and look both ways at street intersections. Remember that
a bicycle always loses in a collision with a motor vehicle, so be prepared to yield even if you have the
right of way.
6. Use approved hand signals for turning and stopping.
7. Never ride with headphones. They mask traffic sounds and emergency vehicle sirens, distract you from
concentrating on what’s going on around you, and their wires can tangle in the moving parts of the
bicycle, causing you to lose control.
8. Never carry a passenger, unless it is a small child wearing an approved helmet and secured in a correctly
mounted child carrier or a child-carrying trailer.
9. Never carry anything which obstructs your vision or your complete control of the bicycle, or which could
become entangled in the moving parts of the bicycle.
10. Never hitch a ride by holding on to another vehicle.
11. Don’t do stunts, wheelies or jumps. If you intend to do stunts, wheelies, jumps or go racing with your bike
despite our advice not to, read Section 2.F, Downhill, Stunt or Competition Biking, now. Think carefully
about your skills before deciding to take the large risks that go with this kind of riding.
12. Don’t weave through traffic or make any moves that may surprise people with whom you are sharing the
road.
13. Observe and yield the right of way.
14. Never ride your bicycle while under the influence of alcohol or drugs.
15. If possible, avoid riding in bad weather, when visibility is obscured, at dawn, dusk or in the dark, or when
extremely tired. Each of these conditions increases the risk of accident.
10
C. Off Road Safety
We recommend that children not ride on rough terrain unless they are accompanied by an adult.
!
1. The variable conditions and hazards of off-road riding require close attention and specific skills. Start
slowly on easier terrain and build up your skills. If your bike has suspension, the increased speed you may
develop also increases your risk of losing control and falling. Get to know how to handle your bike safely
before trying increased speed or more difficult terrain.
2. Wear safety gear appropriate to the kind of riding you plan to do.
3. Don’t ride alone in remote areas. Even when riding with others, make sure that someone knows where
you’re going and when you expect to be back.
4. Always take along some kind of identification, so that people know who you are in case of an accident;
and take along a couple of dollars in cash for a candy bar, a cool drink or an emergency phone call.
5. Yield right of way to pedestrians and animals. Ride in a way that does not frighten or endanger them, and
give them enough room so that their unexpected moves don’t endanger you.
6. Be prepared. If something goes wrong while you’re riding off-road, help may not be close.
7. Before you attempt to jump, do stunt riding or race with your bike, read and understand Section 2.F.
Off Road respect
!
Obey the local laws regulating where and how you can ride off-road, and respect private property. You may
be sharing the trail with others — hikers, equestrians, other cyclists. Respect their rights. Stay on the
designated trail. Don’t contribute to erosion by riding in mud or with unnecessary sliding. Don’t disturb the
ecosystem by cutting your own trail or shortcut through vegetation or streams. I t is your responsibility to
minimize your impact on the environment. Leave things as you found them; and always take out everything
you brought in.
!
D. Wet Weather Riding
!
WARNING: Wet weather impairs traction, braking and visibility, both for the cyclist and for other
vehicles sharing the road. The risk of an accident is dramatically increased in wet conditions.
!
Under wet conditions, the stopping power of your brakes (as well as the brakes of other vehicles sharing the
road) is dramatically reduced and your tires don’t grip nearly as well. This makes it harder to control speed
and easier to lose control. To make sure that you can slow down and stop safely in wet conditions, ride more
slowly and apply your brakes earlier and more gradually than you would under normal, dry conditions. See
also Section 4.C.
11
E. Night Riding
Riding a bicycle at night is many times more dangerous than riding during the day. A cyclist is very difficult
for motorists and pedestrians to see. Therefore, children should never ride at dawn, at dusk or at night.
Adults who chose to accept the greatly increased risk of riding at dawn, at dusk or at night need to take extra
care both riding and choosing specialized equipment which helps reduce that risk. Consult your dealer about
night riding safety equipment.
!
WARNING: Reflectors are not a substitute for required lights. Riding at dawn, at dusk, at night
or at other times of poor visibility without an adequate bicycle lighting system and without
reflectors is dangerous and may result in serious injury or death.
!
Bicycle reflectors are designed to pick up and reflect car lights and street lights in a way that may help you to
be seen and recognized as a moving cyclist.
!
CAUTION: Check reflectors and their mounting brackets regularly to make sure that they are
clean, straight, unbroken and securely mounted. Have your dealer replace damaged reflectors and
straighten or tighten any that are bent or loose.
The mounting brackets of front and rear reflectors are often designed as brake straddle cable safety catches
which prevent the straddle cable from catching on the tire tread if the cable jumps out of its yoke or breaks.
!
WARNING: Do not remove the front or rear reflectors or reflector brackets from your bicycle.
They are an integral part of the bicycle’s safety system.
Removing the reflectors may reduce your visibility to others using the roadway. Being struck
by other vehicles may result in serious injury or death.
The reflector brackets may protect you from the brake straddle cable catching on the tire in the
event of brake cable failure. If a brake straddle cable catches on the tire, it can cause the wheel to
stop suddenly, causing you to loose control and fall.
!
If you choose to ride under conditions of poor visibility, check and be sure you comply with all local laws
about night riding, and take the following strongly recommended additional precautions:
• Purchase and install battery or generator powered head and tail lights which meet all regulatory
requirements and provide adequate visibility.
• Wear light colored, reflective clothing and accessories, such as a reflective vest, reflective arm and leg
bands, reflective stripes on your helmet, flashing lights attached to your body and/or your bicycle ... any
reflective device or light source that moves will help you get t he attention of approaching motorists,
pedestrians and other traffic.
• Make sure your clothing or anything you may be carrying on the bicycle does not obstruct a reflector or
light.
• Make sure that your bicycle is equipped with correctly positioned and securely mounted reflectors.
While riding at dawn, at dusk or at night:
• Ride slowly.
• Avoid dark areas and areas of heavy or fast-moving traffic.
• Avoid road hazards.
• If possible, ride on familiar routes.
If riding in traffic:
• Be predictable. Ride so that drivers can see you and predict your movements.
• Be alert. Ride defensively and expect the unexpected.
• If you plan to ride in traffic often, ask your dealer about traffic safety classes or a good book on bicycle
traffic safety.
12
F. Extreme, stunt or competition riding
Whether you call it Hucking, Freeride, North Shore, Downhill, Jumping, Stunt Riding, Racing or something
else: by engaging in this sort of extreme, aggressive riding you voluntarily assume an increased risk of injury
or death.
Not all bicycles are designed for these types of riding, and those that are may not be suitable for all types of
aggressive riding. Check with your dealer or the bicycle’s manufacturer about the suitability of your bicycle
before engaging in extreme riding.
When riding fast down hill, you can reach speeds seen on motorcycles, and therefore face similar hazards
and risks. Have your bicycle and equipment carefully inspected by a qualified mechanic and be sure it is in
perfect condition. Consult with expert riders and race officials on conditions and equipment advisable at the
site where you plan to ride. Wear appropriate safety gear, including an approved full face helmet, full finger
gloves, and body armor. Ultimately, it is your responsibility to have proper equipment and to be familiar with
course conditions.
!
WARNING: Although many catalogs, advertisements and articles about bicycling depict riders
engaged in extreme riding, this activity is extremely dangerous, increases your risk of injury or
death, and increases the severity of any injury. Remember that the action depicted is being
performed by professionals with many years of training and experience. Know your limits and
always wear a helmet and other appropriate safety gear. Even with state-of-the-art protective safety
gear, you could be seriously injured or killed when jumping, stunt riding, riding downhill at speed or
in competition.
!
CAUTION: Bicycles and bicycle parts have limitations with regard to strength and integrity,
and this type of riding can exceed those limitations.
!
We recommend against this type of riding because of the increased risks; but if you choose to take the risk,
at least:
• Take lessons from a competent instructor first
• Start with easy learning exercises and slowly develop your skills before trying more difficult or dangerous
riding
• Do stunts, jumping, racing or fast downhill riding only in areas designated for this type of riding
• Wear a full face helmet, safety pads and other safety gear
• Understand and recognize that the stresses imposed on your bike by this kind of activity may break or
damage parts of the bicycle and void the warranty
• Take your bicycle to your dealer if anything breaks or bends. Do not ride your bicycle when any part is
damaged.
If you ride downhill at speed, do stunt riding or ride in competition, know the limits of your skill and
experience. Ultimately, avoiding injury is your responsibility.
!
13
G. Changing Components or Adding Accessories
There are many components and accessories available to enhance the comfort, performance and
appearance of your bicycle. However, if you change components or add accessories, you do so at your
own risk. The bicycle’s manufacturer may not have tested that component or accessory for compatibility,
reliability or safety on your bicycle. Before installing any compon ent or accessory, including a different size
tire, make sure that it is compatible with your bicycle by checking with your dealer. Be sure to read,
understand and follow the instructions that accompany the products you purchase for your bicycle. See
also Appendix A p. 33.
!
WARNING: Failure to confirm compatibility, properly install, operate and maintain any
component or accessory can result in serious injury or death.
CAUTION: Changing the components on your bike may void the warranty. Refer to
your warranty, and check with your dealer before changing the components on your bike.
14
3. Fit
NOTE: Correct fit is an essential element of bicycling safety, performance and comfort. Making the
adjustments to your bicycle which result in correct fit for your body and riding conditions requires
experience, skill and special tools. Always have your dealer make the adjustments on your bicycle;
or, if you have the experience, skill and tools, have your dealer check your work before riding.
!
WARNING: If your bicycle does not fit properly, you may lose control and fall. If your new bike
doesn’t fit, ask your dealer to exchange it before you ride it.
A. Standover height
Standover height is the basic element of bike fit (see fig. 2). It is the
distance from the ground to the top of the bicycle’s frame at that point where
your crotch is when straddling the bike. To check for correct standover height,
straddle the bike while wearing the kind of shoes in which you’ll be riding,
and bounce vigorously on your heels. If your crotch touches the frame, the
bike is too big for you. Don’t even ride the bike around the block. A bike
which you ride only on paved surfaces and never take off-road should give
you a minimum standover height clearance of two inches (5 cm). A bike that
you’ll ride on unpaved surfaces should give you a minimum of three inches
(7.5 cm) of standover height clearance. And a bike that you’ll use off road
should give you four inches (10 cm )or more of clearance.
WARNING: If you pla n to use your bike for jumping or stunt riding, read Sectio n 2.F again.
Fig.2
B. Saddle position
Correct saddle adjustment is an important factor in getting the most
performance and comfort from your bicycle. If the saddle position is not
comfortable for you, see your dealer.
The saddle can be adjusted in three directions:
1. Up and down adjustment. To check for correct saddle height (fig. 3):
• sit on the saddle;
• place one heel on a pedal;
• rotate the crank until the pedal with your heel on it is in the down
position and the crank arm is parallel to the seat tube.
If your leg is not completely straight, your saddle height needs to be
adjusted. If your hips must rock for the heel to reach the pedal, the saddle is too high. If your leg is bent
at the knee with your heel on the pedal, the saddle is too low.
!
Fig.3
15
Once the saddle is at the correct height, make sure that the seatpost does not project from the frame beyond
its “Minimum Insertion” or “Maximum Extension” mark. T
frame at least 80mm
WARNING: A seatpost that is positioned too high can damage the bike and can cause you to
lose control and fall. Make sure the seat post is inserted in the frame at least 80mm.
. (see fig. 4).
80mm
he seatpost should always be inserted in the
Fig.4
!
2. Front and back adjustment. The saddle can be adjusted forward or back to help you get the optimal
position on the bike. Ask your dealer to set the saddle for your optimal riding position and to show you how
to make this adjustment.
3. Saddle angle adjustment. Most people prefer a horizontal saddle; but some riders like the saddle nose
angled up or down just a little. Your dealer can adjust saddle angle or teach you how to do it.
Note: If your bicycle is equipped with a suspension seat post, periodically ask your dealer to
check it.
!
Small changes in saddle position can have a substantial effect on performance and comfort. To find your
best saddle position, make only one adjustment at a time.
!
WARNING: After any saddle adjustment, be sure that the saddle adjusting mechanism is
properly tightened before riding. A loose saddle clamp or seat post binder can cause damage to
the seat post, or can cause you to lose control and fall. A correctly tightened saddle adjusting
mechanism will allow no saddle movement in any direction. Periodically check to make sure that
the saddle adjusting mechanism is properly tightened.
!
Warning: When tightening the aluminium bolt too tightly it may break off under circumstances
with the result of the saddle coming loose. In case of any doubt: have the bolt checked by your local
dealer!”
If, in spite of carefully adjusting the saddle height, tilt and fore-and-aft position, your saddle is still
uncomfortable, you may need a different saddle design. Saddles, like people, come in many different
shapes, sizes and resilience. Your dealer can help you select a saddle which, when correctly adjusted for
your body and riding style, will be comfortable.
WARNING: Some people have claimed that extended riding with a saddle which is incorrectly
adjusted or which does not support your pelvic area correctly can cause short-term or long-term
injury to nerves and blood vessels, or even impotence. If your saddle causes you pain, numbness or
other discomfort, listen to your body and stop riding until you see your dealer about saddle
adjustment or a different saddle.

C. Handlebar height and angle
Your bike is equipped either with a “threadless” stem, which clamps on to the outside of the steerer tube, or
with a “quill” stem, which clamps inside the steerer tube by way of an expanding binder bolt. If you aren’t
absolutely sure which type of stem your bike has, ask your dealer.
If your bike has a “threadless” stem, your dealer may be able to change handlebar height by moving height
adjustment spacers from below the stem to above the stem, or vice versa. Otherwise, you’ll have to get a
stem of different length or rise. Consult your dealer. Do not attempt to do this yourself, as it requires special
knowledge.
If your bike has a “quill” stem, you can ask your dealer to adjust the handlebar height a bit by adjusting stem
height.
A quill stem has an etched or stamped mark on its shaft which designates the stem’s “Minimum Insertion” or
“Maximum extension”. This mark must not be visible above the headset.
!
WARNING: On some bicycles, changing the stem or stem height can affect the tension of the
front brake cable, locking the front brake or creating excess cable slack which can make the front
brake inoperable. If the front brake pads move in towards the wheel rim or out away from the wheel
rim when the stem or stem height is changed, the brakes must be correctly adjusted before you
ride the bicycle.
!
WARNING: The stem’s Minimum Insertion Mark must not be visible above the top of the headset.
If the stem is extended beyond the Minimum Insertion Mark the stem may break or damage the fork’s
steerer tube, which could cause you to lose control and fall.
!
Your dealer can also change the angle of the handlebar or bar end extensions.
!
WARNING: An insufficiently tightened stem binder bolt, handlebar binder bolt or bar end
extension clamping bolt 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. 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, the bolts are
insufficiently tightened.
D. Control position adjustments
The angle of the brake and shift control levers and their position on the handlebars can be changed.
Ask your dealer to make the adjustments for you.
E. Brake reach
Many bikes have brake levers which can be adjusted for reach. If you have small hands or find it difficult to
squeeze the brake levers, your dealer can either adjust the reach or fit shorter reach brake levers.
!
WARNING: The shorter the brake lever reach, the more critical it is to have correctly adjusted
brakes, so that full braking power can be applied within available brake lever travel. Brake lever
travel insufficient to apply full braking power can result in loss of control, which may result in
serious injury or death.

4. Tech
!
It’s important to your safety, performance and enjoyment to understand how things work on your bicycle. We
urge you to ask your dealer how to do the things described in this section before you attempt them yourself,
and that you have your dealer check your work before you ride the bike. If you have even the slightest doubt
as to whether you understand something in this section of the Manual, talk to your dealer. See also
Appendix A p. 32.
!
A. Wheels
!
NOTE: If you have a mountain bike equipped with through axle front or rear wheels, make sure
that your dealer has given you the manufacturer’s instructions, and follow those when installing
or removing a through axle wheel. If you don’t know what a through axle is, ask your dealer.
1. Wheel Quick Release
!
WARNING: Riding with an improperly adjusted wheel quick release can allow the wheel to
wobble or fall off the bicycle, which can cause serious injury or death. Therefore, it is essential that
you:
!
1. Ask your dealer to help you make sure you know how to install and remove your wheels safely.
2. Understand and apply the correct technique for clamping your wheel in place with a quick release.
3. Each time, before you ride the bike, check that the wheel is securely clamped.
The wheel quick release uses a cam action to clamp the bike’s wheel in place (see fig. 5). Because of its
adjustable nature, it is critical that you understand how it works, how to use it properly, and how much
force you need to apply to secure the wheel.
Fig.5
!
!WARNING: The full force of the cam action is needed to clamp the wheel securely. Holding the
nut with one hand and turning the lever like a wing nut with the other hand until everything is as
tight as you can get it will not clamp the wheel safely in the dropouts.
18
a. Adjusting the quick release mechanism
The wheel hub is clamped in place by the force of the quick release cam pushing against one dropout and
pulling the tension adjusting nut, by way of the skewer, against the other dropout. The amount of clamping
force is controlled by the tension adjusting nut. Turning the tension adjusting nut clockwise while keeping
the cam lever from rotating increases clamping force; turning it counterclockwise while keeping the cam
lever from rotating reduces clamping force. Less than half a turn of the tension adjusting nut can make the
difference between safe clamping force and unsafe clamping force.
!
b. Front Wheel Secondary Retention Devices
Most bicycles have front forks which utilize a secondary wheel retention device to reduce the risk of the
wheel disengaging from the fork if the quick release is incorrectly adjusted. Secondary retention devices
are not a substitute for correct quick release adjustment.
Secondary retention devices fall into two basic categories:
(1) The clip-on type is a part which the manufacturer adds to the front wheel hub or front fork.
(2) The integral type is molded, cast or machined into the outer faces of the front fork dropouts.
Ask your dealer to explain the particular secondary retention device on your bike.
!
WARNING: Do not remove or disable the secondary retention device. As its name implies, it
serves as a back-up for a critical adjustment. If the quick release is not adjusted correctly, the
secondary retention device can reduce the risk of the wheel disengaging from the fork. Removing
or disabling the secondary retention device may also void the warranty.
Secondary retention devices are not a substitute for 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 loose control and fall, resulting in serious injury or death.
2. Removing and Installing Quick Release Wheels
!
a. Removing a Quick Release Front Wheel
!
CAUTION: If your bike has a disc front brake, exercise care in touching it. Discs have sharp
edges and can get very hot during use.
!
(1) If your bike has rim brakes, disengage the brake’s quick-release mechanism to
increase the clearance between the tire and the brake pads (See Section 4.C fig.
12 through 13).
(2) Move the wheel’s quick-release lever from the locked or CLOSED position to the
OPEN position (figs. 6 & 7).
(3) If your front fork does not have a secondary retention device go to step (5).
(4) If your front fork has a clip-on type secondary retention device, disengage it and
go to step (5). If your front fork has an integral secondary retention device,
loosen the tension adjusting nut enough to allow removing the wheel; then go to
the next step.
Fig.6
Fig.7
(5) Raise the front wheel a few inches off the ground and tap the top of the wheel
with the palm of your hand to release the wheel from the front fork.
19
b. Installing a Quick Release Front Wheel
!
CAUTION: If your bike is equipped with disk brakes, be careful not to damage the disk,
caliper or brake pads when re-inserting the disk into the caliper. Never activate a disk brake’s
control lever unless the disk is correctly inserted in the caliper. See also Section 4.C.
!
(1) Move the quick-release lever so that it curves away from the wheel (fig. 7). This is the OPEN position.
(2) With the steering fork facing forward, insert the wheel between the fork blades so that the axle seats
firmly at the top of the slots which are at the tips of the fork blades — the fork dropouts. The
quick-release lever should be on the left side of the bicycle (fig.6 & 7). If your bike has a clip-on type
secondary retention device, engage it.
(3) Holding the quick-release lever in the OPEN position with your right hand, tighten the tension adjusting
nut with your left hand until it is finger tight against the fork dropout (fig. 5).
(4) While pushing the wheel firmly to the top of the slots in the fork dropouts, and at the same time centering
the wheel rim in the fork, move the quick-release lever upwards and swing it into the CLOSED position
(fig. 5 & 6). The lever should now be parallel to the fork blade and curved toward the wheel. To apply
enough clamping force, you should have to wrap your fingers around the fork blade for leverage, and the
lever should leave a clear imprint in the palm of your hand.
WARNING: Securely clamping the wheel takes considerable force. 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 your hand, the tension is insufficient. Open the lever; turn
the tension adjusting nut clockwise a quarter turn; then try again.
!
(5) If the lever cannot be pushed all the way to a position parallel to the fork blade, return the lever to the
OPEN position. Then turn the tension adjusting nut counterclockwise one-quarter turn and try tightening the
lever again.
(6) Re-engage the brake quick-release mechanism to restore correct brake pad-to-rim clearance; spin the
wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake lever
and make sure that the brakes are operating correctly.
c. Removing a Quick Release Rear Wheel
!
(1) Shift the rear derailleur to high gear (the smallest, outermost rear sprocket).
(2) If your bike has rim brakes, disengage the brake’s quick-release mechanism to increase the clearance
between the wheel rim and the brake pads (see Section 4.C, figs. 12 through 13).
(3) Pull the derailleur body back with your right hand.
(4) Move the quick-release lever to the OPEN position (fig. 7).
(5) Lift the rear wheel off the ground a few inches and, with the derailleur still pulled back, push the wheel
forward and down until it comes out of the rear dropouts.
20
d. Installing a Quick Release Rear Wheel
!
NOTE: If your bike is equipped with disk brakes, be careful not to damage the disk, caliper or
brake pads when re-inserting the disk into the caliper. Never activate a disk brake’s control lever
unless the disk is correctly inserted in the caliper.
!
(1) Make sure that the rear derailleur is still in its outermost, high gear, position
(2) Pull the derailleur body back with your right hand.
(3) Move the quick-release lever to the OPEN position (see fig. 5). The lever should be on the side of the
wheel opposite the derailleur and freewheel sprockets.
(4) Put the chain on top of the smallest freewheel sprocket. Then, insert the wheel up and back into the
frame dropouts and pull it all the way in to the dropouts.
(5) Tighten the quick-release adjusting nut until it is finger tight against the
frame dropout; then swing the lever toward the front of the bike until it is
parallel to the frame’s chainstay or seatstay and is curved toward the
wheel (fig. 6 & fig. 8). To apply enough clamping force, you should have
to wrap your fingers around a frame tube for leverage, and the lever
should leave a clear imprint in the palm of your hand.
Fig.8
WARNING: Securely clamping the wheel takes considerable
force. If you can fully close the quick release without wrapping your fingers around the
seatstay or chainstay for leverage, and the lever does not leave a clear imprint in the palm of
your hand, the tension is insufficient. Open the lever; turn the tension adjusting nut
clockwise a quarter turn; then try again.
!
The rear wheel must be secured to the bicycle frame with sufficient force so that it cannot be
pulled forward by the chain, even under the greatest pedaling force. If the wheel moves under
pedaling force, the tire can touch the frame, which can cause you to loose control and fall.
!
(6) If the lever cannot be pushed all the way to a position parallel to the chainstay or seatstay tube, return
the lever to the OPEN position. Then turn the adjusting nut counterclockwise one-quarter turn and try
tightening again.
(7) Push the rear derailleur back into position.
(8) Re-engage the brake quick-release mechanism to restore correct brake pad-to-rim clearance; spin the
wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake lever
and make sure that the brakes are operating correctly.
3. Removing and Installing Bolt-On Wheels
!
a. Removing a Bolt-On Front Wheel
Fig.9
(1) If your bike has rim brakes, disengage the brake’s quick-release mechanism to
increase the clearance between the tire and the brake pads (see Section 4.C, figs.
12 through 13).
(2) Using a correct size wrench, loosen the two axle nuts.
(3) If your front fork has a clip-on type secondary retention device, disengage it
and go to he next step. If your front fork has an integral secondary retention device, loosen the axle nuts
enough to allow wheel removal; then go to the next step.
21
(4) Raise the front wheel a few inches off the ground and tap the top of the wheel with the palm of your hand
to knock the wheel out of the fork ends.
b. Installing a Bolt-On Front Wheel
(1) With the steering fork facing forward, insert the wheel between the fork blades so that the axle seats
firmly at the top of the slots which are at the tips of the fork blades. The axle nut washers should be on the
outside, between the fork blade and the axle nut. If your bike has a clip-on type secondary retention device,
engage it.
(2) While pushing the wheel firmly to the top of the slots in the fork dropouts, and at the same time centering
the wheel rim in the fork, use the correct size wrench to tighten the axle nuts enough so that the wheel stays
in place; then use a wrench on each nut simultaneously to tighten the nuts as tight as you can.
(3) Re-engage the brake quick-release mechanism to restore correct brake pad-to-rim clearance; spin the
wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake lever
and make sure that the brakes are operating correctly.
c. Removing a Bolt-On Rear Wheel
!
WARNI N G: If your bike is equipped with an internal gear rear hub, do n ot attempt to rem ove the
rear wheel. The removal and re-installation of internal gear hubs require special knowledge.
Incorrect removal or assembly can result in hub failure, which can cause you to lose control and
fall.
!
(1) If your bike has rim brakes, disengage the brake’s quick-release mechanism to open the clearance
between the tire and the brake pads (see Section 4.C, figs. 12 through 13).
(2) Shift the rear derailleur to high gear (the smallest rear sprocket) and pull the derailleur body back with
your right hand.
(3) Using the correct size wrench, loosen the two axle nuts.
(4) Lift the rear wheel off the ground a few inches and, with the derailleur still pulled back, push the wheel
forward and down until it comes out of the rear dropouts.
d. Installing a Bolt-On Rear Wheel
(1) Shift the rear derailleur to its outermost position and pull the derailleur body back with your right hand.
(2) Put the chain on to the smallest sprocket. Then, insert the wheel into the frame dropouts and pull it up
and back completely in to the dropouts. The axle nut washers should be on the outside, between the frame
and the axle nut.
(3) Using the correct size wrench, tighten the axle nuts enough so that the wheel stays in place; then use a
wrench on each nut simultaneously to tighten the nuts as tight as you can.
(4) Push the rear derailleur back into position.
(5) Re-engage the brake quick-release mechanism to restore correct brake pad-to-rim clearance; spin the
wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake lever
and make sure that the brakes are operating correctly.

B. Seatpost Quick Release
Some bikes are equipped with a quick-release seat post binder. The seatpost quick-release binder works
exactly like the wheel quick-release (Section 4.A.1) While a quick release looks like a long bolt with a lever
on one end and a nut on the other, the quick release uses a cam action to firmly clamp the seat post (see fig.
5).
!
WARNING: Riding with an improperly tightened seat post can allow the saddle to turn or
move and cause you to lose control and fall. Therefore:
1. Ask your dealer to help you make sure you know how to correctly clamp your seat post.
2. Understand and apply the correct technique for clamping your seat post quick release.
3. Before you ride the bike, first check that the seatpost is securely clamped.
Adjusting the seatpost quick release mechanism
The action of the quick release cam squeezes the seat collar around the seat post to hold the seat post
securely in place. The amount of clamping force is controlled by the tension adjusting nut. Turning the
tension adjusting nut clockwise while keeping the cam lever from rotating increases clamping force; turning it
counterclockwise while keeping the cam lever from rotating reduces clamping force. Less than half a turn of
the tension adjusting nut can make the difference between safe and unsafe clamping force.
!
WARNING: The full force of the cam action is needed to clamp the seatpost securely. Holding
the nut with one hand and turning the lever like a wing nut with the other hand until everything is as
tight as you can get it will not clamp the seatpost safely.
WARNING: If you can fully close the quick release without wrapping your fingers around the
seat post or a frame tube for leverage, and the lever does not leave a clear imprint in the palm of
your hand, the tension is insufficient. Open the lever; turn the tension adjusting nut clockwise a
quarter turn; then try again.
C. Brakes
WARNING:
!
1. Riding with improperly adjusted brakes or worn brake pads is dangerous and can result in serious
injury or death.
2. Applying brakes too hard or too suddenly can lock up a wheel, which could cause you to lose
control and fall. Sudden or excessive application of the front brake may pitch the rider over the
handlebars, which may result in serious injury or death.
3. Some bicycle brakes, such as disc brakes (fig. 11) are extremely powerful. Take extra care in
becoming familiar with these brakes and exercise particular care when using them.
fig. 11
Disc brake
23
4. Disc brakes can get extremely hot with extended use. Be careful not to touch a disc brake until it
has had plenty of time to cool.
5. See the brake manufacturer’s instructions for operation and care of your brakes. If you do not
have the manufacturer’s instructions, see your dealer or contact the brake manufacturer.
1. Brake controls and features
It’s very important to your safety that you learn and remember which
fig. 12
brake lever controls which brake on your bike.
!
Make sure that your hands can reach and squeeze the brake levers
comfortably. If your hands are too small to operate the levers
comfortably, consult your dealer before riding the bike. The lever reach
may be adjustable; or you may need a different brake lever design.
Most brakes have some form of quick-release mechanism to allow the
brake quick release is in the open position, the brakes are inoperative.
Ask your dealer to make sure that you understand the way the brake
quick release works on your bike (see figs. 12, 13) and check each time
to make sure both brakes work correctly before you get on the bike.
2. How brakes work
The braking action of a bicycle is a function of the pads and the wheel
rim. To make sure that you have maximum friction available, keep your
wheel rims and brake pads clean and free of dirt, lubricants, waxes or
polishes.
Brakes are designed to control your speed, not just to stop the bike.
Maximum braking force for each wheel occurs at the point just before
the wheel “locks up” (stops rotating) and starts to skid. Once the tire
skids, you actually lose most of your stopping force and all directional control. You need to practice slowing
and stopping smoothly without locking up a wheel. The technique is called progressive brake modulation.
Instead of jerking the brake lever to the position where you think you’ll generate appropriate braking force,
squeeze the lever, progressively increasing the braking force. If you feel the wheel begin to lock up, release
pressure just a little to keep the wheel rotating just short of lockup. It’s important to develop a feel for the
amount of brake lever pressure required for each wheel at different speeds and on different surfaces. To
better understand this, experiment a little by walking your bike and applying different amounts of pressure to
each brake lever, until the wheel locks.
!
!!!!!!!!!!!!!!
fig. 13
When you apply one or both brakes, the bike begins to slow, but your body wants to continue at the speed at
which it was going. This causes a transfer of weight to the front wheel (or, under heavy braking, around the
front wheel hub, which could send you flying over the handlebars).
A wheel with more weight on it will accept greater brake pressure before lockup; a wheel with less weight will
lock up with less brake pressure. So, as you apply brakes and your weight is transferred forward, you need
to shift your body toward the rear of the bike, to transfer weight back on to the rear wheel; and at the same
time, you need to both decrease rear braking and increase front braking force. This is even more important
on descents, because descents shift weight forward.
Two keys to effective speed control and safe stopping are controlling wheel lockup and weight transfer.
This weight transfer is even more pronounced if your bike has a front suspension fork. Front suspension
“dips” under braking, increasing the weight transfer (see also Section 4.F). Practice braking and weight
transfer techniques where there is no traffic or other hazards and distractions.
24
Everything changes when you ride on loose surfaces or in wet weather. Tire adhesion is reduced, so the
wheels have less cornering and braking traction and can lock up with less brake force. Moisture or dirt on
the brake pads reduces their ability to grip. The way to maintain control on loose or wet surfaces is to go
more slowly to begin with.
!
D. Shifting gears
!
Your multi-speed bicycle will have a derailleur drivetrain (see 2. below), an internal gear hub drivetrain (see
3. below) or, in some special cases, a combination of the two.
!
1. How a derailleur drivetrain works
!
If your bicycle has a derailleur drivetrain, the gear-changing mechanism will have:
!
• a rear cassette or freewheel sprocket cluster
• a rear derailleur
• usually a front derailleur
• one or two shifters
• one, two or three front sprockets called chainrings
• a drive chain
a. Shifting Gears
!
There are several different types and styles of shifting controls: levers, twist grips, triggers, combination
shift/brake controls and push-buttons. Ask your dealer to explain the type of shifting controls that are on your
bike, and to show you how they work.
!
The vocabulary of shifting can be pretty confusing. A downshift is a shift to a “lower” or “slower” gear, one
which is easier to pedal. An upshift is a shift to a “higher” or “faster”, harder to pedal gear. What’s confusing
is that what’s happening at the front derailleur is the opposite of what’s happening at the rear derailleur (for
details, read the instructions on Shifting the Rear Derailleur and Shifting the Front Derailleur below). For
example, you can select a gear which will make pedaling easier on a hill (make a downshift) in one of two
ways: shift the chain down the gear “steps” to a smaller gear at the front, or up the gear “steps” to a larger
gear at the rear. So, at the rear gear cluster, what is called a downshift looks like an upshift. The way to keep
things straight is to remember that shifting the chain in towards the centerline of the bike is for accelerating
and climbing and is called a downshift. Moving the chain out or away from the centerline of the bike is for
speed and is called an upshift.
Whether upshifting or downshifting, the bicycle derailleur system design requires that the drive chain be
moving forward and be under at least some tension. A derailleur will sh if t only if you are pedaling forward.
CAUTION: Never move the shifter while pedaling backward, nor pedal backwards immediately
after having moved the shifter. This could jam the chain and cause serious damage to the bicycle.
25
b. Shifting the Rear Derailleur
The rear derailleur is controlled by the right shifter.
!
The function of the rear derailleur is to move the drive chain from one gear sprocket to another. The smaller
sprockets on the gear cluster produce higher gear ratios. Pedaling in the higher gears requires greater
pedaling effort, but takes you a greater distance with each revolution of the pedal cranks. The larger
sprockets produce lower gear ratios. Using them requires less pedaling effort, but takes you a shorter
distance with each pedal crank revolution. Moving the chain from a smaller sprocket of the gear cluster to a
larger sprocket results in a downshift. Moving the chain from a larger sprocket to a smaller sprocket results
in an upshift. In order for the derailleur to move the chain from one sprocket to another, the rider must be
pedaling forward.
!
c. Shifting the Front Derailleur:
The front derailleur, which is controlled by the left shifter, shifts the chain between the larger and smaller
chainrings. Shifting the chain onto a smaller chainring makes pedaling easier (a downshift). Shifting to a
larger chainring makes pedaling harder (an upshift).
!
d. Which gear should I be in?
The combination of largest rear and smallest front gears (fig. 14) is
for the steepest hills. The smallest rear and largest front combination
is for the greatest speed. It is not necessary to shift gears in
sequence. Instead, find the “starting gear” which is right for your
level of ability — a gear which is hard enough for quick acceleration
but easy enough to let you start from a stop without wobbling — and
experiment with upshifting and downshifting to get a feel for the
different gear combinations. At first, practice shifting where there are
no obstacles, hazards or other traffic, until you’ve built up your
confidence. Learn to anticipate the need to shift, and shift to a lower
gear before the hill gets too steep. If you have difficulties with shifting,
the problem could be mechanical adjustment. See your dealer for
help.
WARNING: Never shift a derailleur onto the largest or the
smallest sprocket if the derailleur is not shifting smoothly. The
derailleur may be out of adjustment and the chain could jam,
causing you to lose control and fall.
Fig.14
!
2. How an internal gear hub drivetrain works
If your bicycle has an internal gear hub drivetrain, the gear changing mechanism will consist of:
• a 3, 5, 7, 8 or possibly 12 speed internal gear hub
• one, or sometimes two shifters
• one or two control cables
• one front sprocket called a chainring
• a drive chain
a. Shifting internal gear hub gears
Shifting with an internal gear hub drivetrain is simply a matter of moving the shifter to the indicated
position for the desired gear. After you have moved the shifter to the gear position of your choice, ease
the pressure on the pedals for an instant to allow the hub to complete the shift.
!
26
b. Which gear should I be in?
The numerically lowest gear (1) is for the steepest hills. The numerically largest gear (3, 5, 7 or 12,
depending on the number of speeds of your hub) is for the greatest speed.
Shifting from an easier, “slower” gear (like 1) to a harder, “faster” gear (like 2 or 3) is called an upshift.
Shifting from a harder, “faster” gear to an easier, “slower” gear is called a downshift. It is not necessary to
shift gears in sequence. Instead, find the “starting gear” for the conditions — a gear which is hard enough for
quick acceleration but easy enough to let you start from a stop without wobbling — and experiment with
upshifting and downshifting to get a feel for the different gears. At first, practice shifting where there are no
obstacles, hazards or other traffic, until you’ve built up your confidence. Learn to anticipate the need to shift,
and shift to a lower gear before the hill gets too steep. If you have difficulties with shifting, the problem could
be mechanical adjustment. See your dealer for help.
E. Pedals
1. Toe Overlap is when your toe can touch the front wheel when you turn the handlebars to steer while a
pedal is in the forwardmost position. This is common on small-framed bicycles, and is avoided by keeping
the inside pedal up and the outside pedal down when making sharp turns. On any bicycle, this technique
will also prevent the inside pedal from st riking the ground in a turn.
WARNING: Toe Overlap could cause you to lose control and fall. Ask your dealer to help you
determine if the combination of frame size, crank arm length, pedal design and shoes you will use
results in pedal overlap. Whether you have overlap or not, you must keep the inside pedal up and
the outside pedal down when making sharp turns.
2. Some bicycles come equipped with pedals that have sharp and potentially dangerous surfaces. These
surfaces are designed to add safety by increasing grip between the rider’s shoe and the pedal. If your
bicycle has this type of high-performance pedal, you must take extra care to avoid serious injury from the
pedals’ sharp surfaces. Based on your riding style or skill level, you may prefer a less aggressive pedal
design, or chose to ride with shin pads. Your dealer can show you a number of options and make suitable
recommendations.
3. Toeclips and straps are a means to keep feet correctly positioned and engaged with the pedals. The
toeclip positions the ball of the foot over the pedal spindle, which gives maximum pedaling power. The toe
strap, when tightened, keeps the foot engaged throughout the rotation cycle of the pedal. While toeclips and
straps give some benefit with any kind of shoe, they work most effectively with cycling shoes designed for
use with toeclips. Your dealer can explain how toeclips and straps work. Shoes with deep treaded soles or
welts which might might make it more difficult for you to remove your foot should not be used with toeclips
and straps.
WARNING: Getting into and out of pedals with toeclips and straps requires skill which can only
be acquired with practice. Until it becomes a reflex action, the technique requires concentration
which can distract your attention and cause you to lose control and fall. Practice the use of toeclips
and straps where there are no obstacles, hazards or traffic. Keep the straps loose, and don’t
tighten them until your technique and confidence in getting in and out of the pedals warrants it.
Never ride in traffic with your toe straps tight.
!
4. Clipless pedals (sometimes called “step-in pedals”) are another means to keep feet securely in the
correct position for maximum pedaling efficiency. They have a plate, called a “cleat,” on the sole of the shoe,
which clicks into a mating spring-loaded fixture on the pedal. They only engage or disengage with a very
specific motion which must be practiced until it becomes instinctive. Clipless pedals require shoes and cleats
which are compatible with the make and model pedal being used.
!
27
Many clipless pedals are designed to allow the rider to adjust the amount of force needed to engage or
disengage the foot. Follow the pedal manufacturer’s instructions, or ask your dealer to show you how to
make this adjustment. Use the easiest setting until engaging and disengaging becomes a reflex action, but
always make sure that there is sufficient tension to prevent unintended release of your foot from the pedal.
WARNING: Clipless pedals are intended for use with shoes specifically made to fit them and are
designed to firmly keep the foot engaged with the pedal. Using shoes which do not engage the
pedals correctly is danger ous.
Practice is required to learn to engage and disengage the foot safely. Until engaging and disengaging the
foot becomes a reflex action, the technique requires concentration which can distract your attention and
cause you to lose control and fall. Practice engaging and disengaging clipless pedals in a place where there
are no obstacles, hazards or traffic; and be sure to follow the pedal manufacturer’s setup and service
instructions. If you do not have the manufacturer’s instructions, see your dealer or contact the manufacturer.
F. Bicycle Suspension
Many bicycles are equipped with suspension systems. There are many different types of suspension
systems — too many to deal with individually in this Manual. If your bicycle has a suspension system of any
kind, be sure to read and follow the suspension manufacturer’s setup and service instructions. If you do not
have the manufacturer’s instructions, see your dealer or contact the manufacturer.
!
WARNING: Failure to maintain, check and properly adjust the suspension system may result in
suspension malfunction, which may cause you to lose control and fall.
!
If your bike has suspension, the increased speed you may develop also increases your risk of injury.
For example, when braking, the front of a suspended bike dips. You could lose control and fall if you do
not have experience with this system. Learn to handle your suspension system safely. See also Section
4.C.
!
WARNING: Changing suspension adjustment can change the handling and braking
characteristics of your 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 handling and braking characteristics of the bicycle after a
suspension adjustment by taking a careful test ride in a hazard-free area.
!
Suspension can increase control and comfort by allowing the wheels to better follow the terrain. This
enhanced capability may allow you to ride faster; but you must not confuse the enhanced capabilities of the
bicycle with your own capabilities as a rider. Increasing your skill will take time and practice. Proceed
carefully until you have learned to handle the full capabilities of your bike.
!
CAUTION: Not all bicycles can be safely retrofitted with some types of suspension systems.
Before retrofitting a bicycle with any suspension, check with the bicycle’s manufacturer to make
sure that what you want to do is compatible with the bicycle’s design.

G. Tires and Tubes
1. Tires
!
Bicycle tires are available in many designs and specifications, ranging
from general-purpose designs to tires designed to perform best under
very specific weather or terrain conditions. If, once you’ve gained
experience with your new bike, you feel that a different tire might better
suit your riding needs, your dealer can help you select the most
appropriate design.
!
The size, pressure rating, and on some high-performance tires the
specific recommended use, are marked on the sidewall of the tire (see
fig. 15). The part of this information which is most important to you is
Tire Pressure.
!
WARNING: Never inflate a tire beyond the maximum pressure
marked on the tire’s sidewall. Exceeding the recommended
maximum pressure may blow the tire off the rim, which could
cause damage to the bike and injury to the rider and bystanders.
The best and safest way to inflate a bicycle tire to the correct pressure is with a bicycle pump which has a
built-in pressure gauge.
Fig.15
!
WARNING: There is a safety risk in using gas station air hoses or other air compressors. They
are not made for bicycle tires. They move a large volume of air very rapidly, and will raise the
pressure in your tire very rapidly, which could cause the tube to explode.
Tire pressure is given either as maximum pressure or as a pressure range. How a tire performs under
different terrain or weather conditions depends largely on tire pressure. Inflating the tire to near its maximum
recommended pressure gives the lowest rolling resistance; but also produces the harshest ride. High
pressures work best on smooth, dry pavement.
Very low pressures, at the bottom of the recommended pressure range, give the best performance on
smooth, slick terrain such as hard-packed clay, and on deep, loose surfaces such as deep, dry sand.
Tire pressure that is too low for your weight and the riding conditions can cause a puncture of the tube by
allowing the tire to deform sufficiently to pinch the inner tube between the rim and the riding surface.
CAUTION: Pencil type automotive tire gauges can be inaccurate and should not be relied
upon for consistent, accurate pressure readings. Instead, use a high quality dial gauge.
!
Ask your dealer to recommend the best tire pressure for the kind of riding you will most often do, and have
the dealer inflate your tires to that pressure. Then, check inflation as described in Section 1.C so you’ll know
how correctly inflated tires should look and feel when you don’t have access to a gauge. Some tires may
need to be brought up to pressure every week or two.
Some special high-performance tires have unidirectional treads: their tread pattern is designed to work
better in one direction than in the other. The sidewall marking of a unidirectional tire will have an arrow
showing the correct rotation direction. If your bike has unidirectional tires, be sure that they are mounted to
rotate in the correct direction.
29
2. Tire Valves
There are primarily three kinds of bicycle tube valves: The Schraeder Valve, the Presta Valve and the
Woods/Dunlop valve. The bicycle pump you use must have the fitting appropriate to the valve stems on
your bicycle.
The Schraeder valve (fig. 16) is like the valve on a car tire. To inflate a Schraeder valve tube, remove the
valve cap and clamp the pump fitting onto the end of the valve stem. To let air out of a Schraeder valve,
depress the pin in the end of the valve stem with the end of a key or other appropriate object.
The Presta valve (fig. 16) has a narrower diameter and is only found on bicycle tires. To inflate a Presta
valve tube using a Presta headed bicycle pump, remove the valve cap; unscrew (counterclockwise) the
valve stem lock nut; and push down on the valve stem to free it up. Then push the pump head on to the
valve head, and inflate. To inflate a Presta valve with a Schraeder pump fitting, you’ll need a Presta adapter
(available at your bike shop) which screws on to the valve stem once you’ve freed up the valve. The adapter
fits into the Schraeder pump fitting. Close the valve after inflation. To let air out of a Presta valve, open up
the valve stem lock nut and depress the valve stem.
There is a third type of valve, which has a bottom similar to a Schrader and necks down to about the size of
a Presta. This is a Woods valve, also known as a "Dunlop" valve. You can pump them up with a Presta
pump.
Fig.16
Woods/Dunlop valvePresta valve Schraeder valve
WARNING: Patching a tube is an emergency repair. If you do not apply the patch correctly or
apply several patches, the tube can fail, resulting in possible tube failure, which could cause you to
loose control and fall. Replace a patched tube as soon as possible.
30
5. Service
!
WARNING: Technological advances have made bicycles and bicycle components more
complex, and the pace of innovation is increasing. It is impossible for this manual to provide all the
information required to properly repair and/or maintain your bicycle. In order to help minimize the
chances of an accident and possible injury, it is critical that you have any repair or maintenance
which is not specifically described in this manual performed by your dealer. Equally important is that
your individual maintenance requirements will be determined by everything from your riding style to
geographic location. Consult your dealer for help in determining your maintenance requirements.
WARNING: Many bicycle service and repair tasks require special knowledge and tools. Do not
begin any adjustments or service on your bicycle until you have learned from your dealer how to
properly complete them. Improper adjustment or service may result in damage to the bicycle or in an
accident which can cause serious injury or death.
If you want to learn to do major service and repair work on your bike:
1. Ask your dealer for copies of the manufacturer’s installation and service instructions for the components
on your bike, or contact the component manufacturer.
2. Ask your dealer to recommend a book on bicycle repair.
3. Ask your dealer about the availability of bicycle repair courses in your area.
We recommend that you ask your dealer to check the quality of your work the first time you work on
something and before you ride the bike, just to make sure that you did everything correctly. Since that will
require the time of a mechanic, there may be a modest charge for this service.
A. Service Intervals
Some service and maintenance can and should be performed by the owner, and require no special tools
or knowledge beyond what is presented in this manual.
The following are examples of the type of service you should perform yourself. All other service,
maintenance and repair should be performed in a properly equipped facility by a qualified bicycle
mechanic using the correct tools and procedures specified by the manufacturer.
1. Break-in Period: Your bike will last longer and work better if you break it in before riding it hard. Control
cables and wheel spokes may stretch or “seat” when a new bike is first used and may require
readjustment by your dealer. Your Mechanical Safety Check (Section 1.C) will help you identify some
things that need readjustment. But even if everything seems fine to you, it’s best to take your bike back
to the dealer for a checkup. Dealers typically suggest you bring the bike in for a 30 day checkup. Another
way to judge when it’s time for the first checkup is to bring the bike in after three to five hours of hard
off-road use, or about 10 to 15 hours of on-road or more casual off-road use. But if you think something
is wrong with the bike, take it to your dealer before riding it again.
2. Before every ride: Mechanical Safety Check (Section 1.C)
3. After every long or hard ride: if the bike has been exposed to water or grit; or at least every 100 miles:
Clean the bike and lightly oil the chain. Wipe off excess oil. Lubrication is a function of climate. Talk to
your dealer about the best lubricants and the recommended lubrication frequency for your area.
4. After every long or hard ride or after every 10 to 20 hours of riding:
• Squeeze the front brake and rock the bike forward and back. Everything feel solid? If you feel a clunk
with each forward or backward movement of the bike, you probably have a loose headset. Have your
dealer check it.
31
• Lift the front wheel off the ground and swing it from side to side. Feel smooth? If you feel any binding or
roughness in the steering, you may have a tight headset. Have your dealer check it.
• Grab one pedal and rock it toward and away from the centerline of the bike; then do the same with the
other pedal. Anything feel loose? If so, have your dealer check it.
• Take a look at the brake pads. Starting to look worn or not hitting the wheel rim squarely? Time to have
the dealer adjust or replace them.
• Carefully check the control cables and cable housings. Any rust? Kinks? Fraying? If so, have your dealer
replace them.
• Squeeze each adjoining pair of spokes on either side of each wheel between your thumb and index
finger. Do they all feel about the same? If any feel loose, have your dealer check the wheel for tension
and trueness.
• Check to make sure that all parts and accessories are still secure, and tighten any which are not.
• Check the frame, particularly in the area around all tube joints; the handlebars; the stem; and the
seatpost for any deep scratches, cracks or discoloration. These are signs of stress-caused fatigue and
indicate that a part is at the end of its useful life and needs to be replaced. See also Appendix A.
WARNING: Like any mechanical device, a bicycle and its components are subject to wear and
stress. Different materials and mechanisms wear or fatigue from stress at different rates and have
different life cycles. If a component’s life cycle is exceeded, the component can suddenly and
catastrophically fail, causing serious injury or death to the rider. Scratches, cracks, fraying and
discoloration are signs of stress-caused fatigue and indicate that a part is at the end of its useful life
and needs to be replaced. While the materials and workmanship of your bicycle or of individual
components may be covered by a warranty for a specified period of time by the manufacturer, this is
no guarantee that the product will last the term of the warranty. Product life is often related to the
kind of riding you do and to the treatment to which you submit the bicycle. The bicycle’s warranty is
not meant to suggest that the bicycle cannot be broken or will last forever. It only means that the
bicycle is covered subject to the terms of the warranty. Please be sure to read Appendix A, Life
expectancy of your bicycle and its components, starting on page 33.
!
5. As required: If either brake lever fails the Mechanical Safety Check (Section 1.C), don’t ride the bike.
Have your dealer check the brakes.
If the chain won’t shift smoothly and quietly from gear to gear, the derailleur is out of adjustment. See
your dealer.
6. Every 25 (hard off-road) to 50 (on-road) hours of riding: Take your bike to your dealer for a complete
checkup.
B. If your bicycle sustains an impact:
First, check yourself for injuries, and take care of them as best you can. Seek medical help if necessary.
Next, check your bike for damage.
After any crash, take your bike to your dealer for a thorough check. See also Appendix A, Lifespan of
your bike and its components.
!
WARNING: A crash or other impact can put extraordinary stress on bicycle components,
causing them to fatigue prematurely. Components suffering from stress fatigue can fail suddenly
and catastrophically, causing loss of control, serious injury or death.

Appendix A
The lifespan of your bike and its components
!
1. Nothing Lasts Forever, Including Your Bike.
!
When the useful life of your bike or its components is over, continued use is hazardous.
Every bicycle and its component parts have a finite, limited useful life. The length of that life will vary with the
construction and materials used in the frame and components; the maintenance and care the frame and
components receive over their life; and the type and amount of use to which the frame and components are
subjected. Use in competitive events, trick riding, ramp riding, jumping, aggressive riding, riding on severe
terrain, riding in severe climates, riding with heavy loads, commercial activities and other types of
non-standard use can dramatically shorten the life of the frame and components. Any one or a combination
of these conditions may result in an unpredictable failure.
All aspects of use being identical, lightweight bicycles and their components will usually have a shorter life
than heavier bicycles and their components. In selecting a lightweight bicycle or components you are
making a tradeoff, favoring the higher performance that comes with lighter weight over longevity. So, If you
choose lightweight, high performance equipment, be sure to have it inspected frequently.
You should have your bicycle and its components checked periodically by your dealer for indicators of
stress and/or potential failure, including cracks, deformation, corrosion, paint peeling, dents, and any other
indicators of potential problems, inappropriate use or abuse. These are important safety checks and very
important to help prevent accidents, bodily injury to the rider and shortened product life.
2. Perspective
Today’s high-performance bicycles require frequent and careful inspection and service. In this Appendix
we try to explain some underlying material science basics and how they relate to your bicycle. We discuss
some of the trade-offs made in designing your bicycle and what you can expect from your bicycle; and we
provide important, basic guidelines on how to maintain and inspect it. We cannot teach you everything you
need to know to properly inspect and service your bicycle; and that is why we repeatedly urge you to take
your bicycle to your dealer for professional care and attention.
WARNING: Frequent inspection of your bike is important to your safety. Follow the Mechanical
Safety Check in Section 1.C of this Manual before every ride.
Periodic, more detailed inspection of your bicycle is important. How often this more detailed
inspection is needed depends upon you.
You, the rider/owner, have control and knowledge of how often you use your bike, how hard you
use it and where you use it. Because your dealer cannot track your use, you must take
responsibility for periodically bringing your bike to your dealer for inspection and service. Your
dealer will help you decide what frequency of inspection and service is appropriate fo r how and
where you use your bike.
For your safety, understanding and communication with your dealer, we urge you to read this
Appendix in its entirety. The materials used to make your bike determine how and how frequently to
inspect.
Ignoring this WARNING can lead to frame, fork or other component failure, which can result in
serious injury or death.

A. Understanding metals
!
Steel is the traditional material for building bicycle frames. It has good characteristics, but in high
performance bicycles, steel has been largely replaced by aluminum and some titanium. The main factor
driving this change is interest by cycling enthusiasts in lighter bicycles.
Properties of Metals
!
Please understand that there is no simple statement that can be made that characterizes the use of different
metals for bicycles. What is true is how the metal chosen is applied is much more important than the
material alone. One must look at the way the bike is designed, tested, manufactured, supported along with
the characteristics of the metal rather than seeking a simplistic answer.
Metals vary widely in their resistance to corrosion. Steel must be protected or rust will attack it. Aluminum
and Titanium quickly develop an oxide film that protects the metal from further corrosion. Both are therefore
quite resistant to corrosion. Aluminum is not perfectly corrosion resistant, and particular care must be used
where it contacts other metals and galvanic corrosion can occur.
Metals are comparatively ductile. Ductile means bending, buckling and stretching before breaking.
Generally speaking, of the common bicycle frame building materials steel is the most ductile, titanium less
ductile, followed by aluminum.
Metals vary in density. Density is weight per unit of material. Steel weighs 7.8 grams/cm3 (grams per cubic
centimeter), titanium 4.5 grams/cm3, aluminum
2.75 grams/cm3. Contrast these numbers with carbon fiber composite at 1.45 grams/cm3.
Metals are subject to fatigue. With enough cycles of use, at high enough loads, metals will eventually
develop cracks that lead to failure. It is very important that you read The basics of metal fatigue below.
Let’s say you hit a curb, ditch, rock, car, another cyclist or other object. At any speed above a fast walk, your
body will continue to move forward, momentum carrying you over the front of the bike. You cannot and will
not stay on the bike, and what happens to the frame, fork and other components is irrelevant to what
happens to your body.
What should you expect from your metal frame? It depends on many complex factors, which is why we tell
you that crashworthiness cannot be a design criteria. With that important note, we can tell you that if the
impact is hard enough the fork or frame may be bent or buckled. On a steel bike, the steel fork may be
severely bent and the frame undamaged. Aluminum is less ductile than steel, but you can expect the fork
and frame to be bent or buckled. Hit harder and the top tube may be broken in tension and the down tube
buckled. Hit harder and the top tube may be broken, the down tube buckled and broken, leaving the head
tube and fork separated from the main triangle.
When a metal bike crashes, you will usually see some evidence of this ductility in bent, buckled or folded
metal. It is now common for the main frame to be made of metal and the fork of carbon fiber. See Section B,
Understanding composites below. The relative ductility of metals and the lack of ductility of carbon fiber
means that in a crash scenario you can expect some bending or bucking in the metal but none in the carbon.
Below some load the carbon fork may be intact even though the frame is damaged. Above some load the
carbon fork will be completely broken.
36
The basics of metal fatigue
Common sense tells us that nothing that is used lasts forever. The more you use something, and the harder
you use it, and the worse the conditions you use it in, the shorter its life.
Fatigue is the term used to describe accumulated damage to a part caused by repeated loading. To cause
fatigue damage, the load the part receives must be great enough. A crude, often-used example is bending a
paper clip back and forth (repeated loading) until it breaks. This simple definition will help you understand
that fatigue has nothing to do with time or age. A bicycle in a garage does not fatigue. Fatigue happens only
through use.
So what kind of “damage” are we talking about? On a microscopic level, a crack forms in a highly stressed
area. As the load is repeatedly applied, the crack grows. At some point the crack becomes visible to the
naked eye. Eventually it becomes so large that the part is too weak to carry the load that it could carry
without the crack. At that point there can be a complete and immediate failure of the part.
One can design a part that is so strong that fatigue life is nearly infinite. This requires a lot of material and a
lot of weight. Any structure that must be light and strong will have a finite fatigue life. Aircraft, race cars,
motorcycles all have parts with finite fatigue lives. If you wanted a bicycle with an infinite fatigue life, it would
weigh far more than any bicycle sold today. So we all make a tradeoff: the wonderful, lightweight
performance we want requires that we inspect the structure.
A few things to think about
• ONCE A CRACKS STARTS IT CAN GROW AND GROW
FAST. Think about the crack as forming a pathway to
failure. This means that any crack is potentially dangerous
and will only become more dangerous.
• CORROSSION SPEEDS DAMAGE. Cracks grow more
quickly when they are in a corrosive environment. Think
about the corrosive solution as further weakening and
extending the crack.
SIMPLE RULE 1 :
If you find crack, replace the part.
SIMPLE RULE 2 :
Clean your bike, lubricate your bike, protect
your bike from salt, remove any salt as
soon as you can.
• STAINS AND DISCOLORATION CAN OCCUR NEAR A
CRACK. Such staining may be a warning sign that a crack
exists.
• SIGNIFICANT SCRATCHES, GOUGES, DENTS OR
SCORING CREATE STARTING POINTS FOR CRACKS.
Think about the cut surface as a focal point for stress (in
fact engineers call such areas “stress risers,” areas where
the stress is increased). Perhaps you have seen glass cut?
Recall how the glass was scored and then broke on the
scored line.
• SOME CRACKS (particularly larger ones) MAY MAKE
CREAKING NOISE AS YOU RIDE. Think about such a
noise as a serious warning signal. Note that a
well-maintained bicycle will be very quiet and free of creaks
and squeaks.
37
SIMPLE RULE 3 :
Inspect and investigate any staining to see
if it is associated with a crack.
SIMPLE RULE 4 :
Do not scratch, gouge or score any
surface. If you do, pay frequent attention to
this area or replace the part.
SIMPLE RULE 5 :
Investigate and find the source of any
noise. It may not a be a crack, but
whatever is causing the noise should be
fixed promptly.
In most cases a fatigue crack is not a defect. It is a sign that the part has been worn out, a sign the part has
reached the end of its useful life. When your car tires wear down to the point that the tread bars are
contacting the road, those tires are not defective. Those tires are worn out and the tread bar says “time for
replacement.” When a metal part shows a fatigue crack, it is worn out. The crack says “time for
replacement.”
Fatigue Is Not A Perfectly Predictable Science
Fatigue is not a perfectly predictable science, but here are some general factors to help you and your dealer
determine how often your bicycle should be inspected. The more you fit the “shorten product life” profile, the
more frequent your need to inspect. The more you fit the “lengthen product life” profile, the less frequent
your need to inspect.
!
Factors that shorten product life:
•Hard, harsh riding style
•“Hits,” crashes, jumps, other “shots” to bike
•High mileage
•Higher body weight
•Stronger, more fit, more aggressive rider
•Corrosive environment (wet, salt air, winter road salt,
accumulated sweat)
•Presence of abrasive mud, dirt, sand, soil in riding
environment
!
Factors that lengthen product life:
•Smooth, fluid riding style
•No “hits,” crashes, jumps, other “shots” to bike
•Low mileage
•Lower body weight
•Less aggressive rider
•Non-corrosive environment (dry, salt-free air)
•Clean riding environment
WARNING: Do not ride a bicycle or component with any crack, bulge or dent, even a small one.
Riding a cracked frame, fork or component could lead to complete failure, with risk of serious injury
or death.
!
B. Understanding composites
All riders must understand a fundamental reality of composites. Composite materials constructed of carbon
fibers are strong and light, but when crashed or overloaded, carbon fibers do not bend, they break.
!
What Are Composites?
The term “composites” refers to the fact that a part or parts are made up of different components or
materials. You’ve heard the term “carbon fiber bike.” This really means “composite bike.”
Carbon fiber composites are typically a strong, light fiber in a matrix of plastic, molded to form a shape.
Carbon composites are light relative to metals. Steel weighs 7.8 grams/cm3 (grams per cubic centimeter),
titanium 4.5 grams/ cm3, aluminum 2.75 grams/cm3. Contrast these numbers with carbon fiber composite at
1.45 grams/cm3.
The composites with the best strength-to-weight ratios are made of carbon fiber in a matrix of epoxy plastic.
The epoxy matrix bonds the carbon fibers together, transfers load to other fibers, and provides a smooth
outer surface. The carbon fibers are the “skeleton” that carries the load.
38
Why Are Composites Used?
Unlike metals, which have uniform properties in all directions (engineers call this isotropic), carbon fibers can
be placed in specific orientations to optimize the structure for particular loads. The choice of where to place
the carbon fibers gives engineers a powerful tool to create strong, light bicycles. Engineers may also orient
fibers to suit other goals such as comfort and vibration damping.
Carbon fiber composites are very corrosion resistant, much more so than most metals. Think about carbon
fiber or fiberglass boats.
Carbon fiber materials have a very high strength-to-weight ratio.
What Are The Limits Of Composites?
Well designed “composite” or carbon fiber bicycles and components have long fatigue lives, usually better
than their metal equivalents.
While fatigue life is an advantage of carbon fiber, you must still regularly inspect your carbon fiber frame,
fork, or components.
Carbon fiber composites are not ductile. Once a carbon structure is overloaded, it will not bend; it will
break. At and near the break, there will be rough, sharp edges and maybe delamination of carbon fiber or
carbon fiber fabric layers. There will be no bending, buckling, or stretching.
If You Hit Something Or Have A Crash, What Can You Expect From Your Carbon Fiber Bike?
Let’s say you hit a curb, ditch, rock, car, other cyclist or other object. At any speed above a fast walk, your
body will continue to move forward, the momentum carrying you over the front of the bike. You cannot and
will not stay on the bike and what happens to the frame fork and other components is irrelevant to what
happens to your body.
What should you expect from your carbon frame? It depends on many complex factors, which is why we tell
you that crash worthiness cannot be a design criteria. With that important note, we can tell you that if the
impact is hard enough, the fork or frame may be completely broken. Note the significant difference in
behavior between carbon and metal. See Section 2. A, Understanding metals in this Appendix. Even if the
carbon frame was twice as strong as a metal frame, once the carbon frame is overloaded it will not bend, it
will break completely.
WARNING:
Never use clamping devices on the tubes of carbon frames. This can cause serious damage to
the carbon frame.
WARNING:
Never use clamps on carbon frames. Clamps such as those found on bicycle work stands and car
racks can damage the carbon frame.
Inspection of Composite Frame, Fork, and Components Cracks:
Inspect for cracks, broken, or splintered areas. Any crack is serious. Do not ride any bicycle or component
that has a crack of any size.
39
Delamination:
Delamination is serious damage. Composites are made from layers of fabric. Delamination means that the
layers of fabric are no longer bonded together. Do not ride any bicycle or component that has any
delamination. These are some delamination clues:
• A cloudy or white area. This kind of area looks different from the ordinary undamaged areas. Undamaged
areas will look glassy, shiny, or “deep,” as if one was looking into a clear liquid. Delaminated areas will
look opaque and cloudy.
• Bulging or deformed shape. If delamination occurs, the surface shape may change. The surface may
have a bump, a bulge, soft spot, or not be smooth and fair.
• A difference in sound when tapping the surface. If you gently tap the surface of an undamaged composite
you will hear a consistent sound, usually a hard, sharp sound. If you then tap a delaminated area, you
will hear a different sound, usually duller, less sharp.
Unusual Noises:
Either a crack or delamination can cause creaking noises while riding. Think about such a noise as a serious
warning signal. A well maintained bicycle will be very quiet and free of creaks and squeaks. Investigate and
find the source of any noise. It may not be a crack or delamination, but whatever is causing the noise must
be fixed before riding.
!
WARNING: Do not ride a bicycle or component with any delamination or crack. Riding a delaminated
or cracked frame, fork or other component could lead to complete failure, with risk of serious injury
or death.
!
C. Understanding components
It is often necessary to remove and disassemble components in order to properly and carefully inspect
them. This is a job for a professional bicycle mechanic with the special tools, skills and experience to
inspect and service today’s high-tech high-performance bicycles and their components.
!
Aftermarket “Super Light” components
Think carefully about your rider profile as outlined above. The more you fit the “shorten product life” profile,
the more you must question the use of super light components. The more you fit the “lengthen product life”
profile, the more likely it is that lighter components may be suitable for you. Discuss your needs and your
profile very honestly with your dealer. Take these choices seriously and understand that you are responsible
for the changes.
A useful slogan to discuss with your dealer if you contemplate changing components is “Strong, Light,
Cheap –pick two.”
!
Original Equipment components
Bicycle and component manufacturers tests the fatigue life of the components that are original
equipment on your bike. This means that they have met test criteria and have reasonable fatigue life. It
does not mean that the original components will last forever. They won’t.

Article 4 Procedure
4.1 On delivery of the bike to the first owner, a guarantee registration card and a duplicate guarantee
registration card are being issued. After delivery of the bike, the guarantee registration card is to be
completed by the first owner of the bike and sent to Giant Europe B.V. A claim on the guarantee will no
sooner be discussed than after receipt of a guarantee registration card by Giant Europe B.V.
4.2 The claims that come under the competence of this guarantee are to be issued with an acknowledged
Giant dealer.
4.3 While issuing a claim with an acknowledged dealer that comes under the competence of this guarantee,
a prove of purchase must be handed over. Furthermore, the first owner must also hand over the
duplicate guarantee registration card to the Giant dealer.
4.4 On issuing the claim, the Giant dealer completes a guarantee application form that in all cases must
include the following data: name and address of the owner of the bike, date of purchase, frame number
of the bike, description of the part that comes under the guarantee, stamp of the Giant dealer. 4.5 In the
event that a guarantee is acknowledged by Giant, then Giant shall take care of replacement or
reimbursement of the part concerned.
