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.
• 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 B.
