3. a difference in sound when tapping the surface. if you gently tap the surface of an undamaged composite you will hear a
consistent sound, usually a hard, sharp sound. if you then tap a delaminated area, you will hear a different sound, usually
duller, less sharp.
Unusual noises:
either a crack or delamination can cause creaking noises while riding. think about such a noise as a serious warning signal. a well
maintained bicycle will be very quiet and free of creaks and squeaks. investigate and find the source of any noise. it may not be a crack
or delamination, but whatever is causing the noise must be fixed before riding.

C. Understanding components
it is often necessary to remove and disassemble components in order to properly and carefully inspect them. this is a job for a
professional bicycle mechanic with the special tools, skills and experience to inspect and service today's high-tech high-performance
bicycles and their components.
Aftermarket "super Light" components
think carefully about your rider profile as outlined above. the more you fit the "shorten product life" profile, the more you must question
the use of super light components. the more you fit the "lengthen product life" profile, the more likely it is that lighter components may
be suitable for you. discuss your needs and your profile very honestly with your dealer.
take these choices seriously and understand that you are responsible for the changes.
a useful slogan to discuss with your dealer if you contemplate changing components is "Strong, Light, Cheap –pick two."
original equipment components
Bicycle and component manufacturers test the fatigue life of the components that are original equipment on your bike. this means
that they have met test criteria and have reasonable fatigue life. it does not mean that the original components will last forever.
they won't.

Coaster Brakes
1. How the coaster brake works
the coaster brake is a sealed mechanism which is a part of the bicycle's
rear wheel hub. the brake is activated by reversing the rotation of the
pedal cranks (see fig. 19). start with the pedal cranks in a nearly horizontal
position, with the front pedal in about the 4 o'clock position, and apply
downward foot pressure on the pedal that is to the rear. about 1/8 turn
rotation will activate the brake. the more downward pressure you apply, the
more braking force, up to the point where the rear wheel stops rotating and
begins to skid.

2. Adjusting your coaster brake
Coaster brake service and adjustment requires special tools and special knowledge. do not attempt to disassemble or service your coaster
brake. take the bicycle to your dealer for coaster brake service.

Fastener torque specifications
Correct tightening torque of threaded fasteners is very important to your safety. always tighten fasteners to the correct torque. Bolts that are too
tight can stretch and deform. Bolts that are too loose can move and fatigue. either mistake can lead to a sudden failure of the bolt.
always use a correctly calibrated torque wrench to tighten critical fasteners on your bike. Carefully follow the torque wrench manufacturer's
instructions on the correct way to set and use the torque wrench for accurate results.
the differences in design, material, manufacturing, brand and technological advances make it impractical to provide useful and relevant torque
values for the components, hardware and fasteners found on all models of bicycles covered by this manual. to ensure that the torque values
recommended are appropriate to the components used on your bicycle please contact your local dealer. there are several sources for this
information available through your dealer including but not limited to component manufacturers' websites, tool suppliers, and industry reference
guides for mechanics.
