5.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.
