If Your Bycicle Sustains An Impact; Appendix B: Lifespan Of Your Bike And Its Components - Giant momentum Anleitung

• 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 or of individual components may be covered by a
warranty for a specified 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 subject 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 34.
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 qualified 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
catastrophically, causing loss of control, serious injury or death.
