your thumb and index nger. 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

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, Intended
Use of your bicycle and Appendix B, The lifespan of your bike and its
components, starting on page 43.
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. Carbon
composite components, including fames, wheels, handlebars, stems, cranksets,
brakes, etc. which have sustained an impact must not be ridden until they have
been disassembled and thoroughly inspected by a qualied mechanic.
See also Appendix B, 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
