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 lubricate the chain’s rollers
with a good quality bicycle chain lubricant. Wipe off excess lubricant with a lint-
free cloth. 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.
• 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 the tires for excess wear, cuts or bruises. Have your dealer replace
them if necessary.
• check the wheel rims for excess wear, dings, dents and scratches. Consult
your dealer if you see any rim damage.
• 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 B.
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
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.
We also recommend that you ask your dealer for guidance on what spare
parts, such as inner tubes, light bulbs, etc. it would be appropriate for you to
have once you have learned how to replace such parts when they require
replacement.
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”
