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. 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" 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.
