Appendix C - Coaster Brakes - Kona bicycle Owner's Manual

• 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 differ-
ent 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.
WARNING: Do not ride a bicycle or component with
any delamination or crack. Riding a delaminated or
cracked frame, fork or other component could lead to
complete failure, with risk of serious injury or death.
C) UNDERSTANDING COMPONENTS
It is often necessary to remove and disassemble compo-
nents 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 compo-
nents. The more you fit the "lengthen product life" pro-
file, 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
40
changing components is "Strong, Light, Cheap — pick two."
Original Equipment components
Bicycle and component manufacturers tests 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.
Appendix C
Coaster Brake
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. 5). 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 down-
ward pressure you apply, the more braking force, up to the
point where the rear wheel stops rotating and begins to skid.
WARNING: Before riding, make sure that the brake is
working properly. If it is not working properly, have the
bicycle checked by your dealer before you ride it.
WARNING: If your bike has only a coaster brake, ride
conservatively. A single rear brake does not have the
stopping power of front-and-rear brake systems.
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.
