securing method for your bicycle with your
dealer.
It is very important that you understand
the type of wheel securing method on
your bicycle, that you know how to
secure the wheels correctly, and that you
know how to apply the correct clamping
force that safely secures the wheel. Ask
your dealer to instruct you in correct
wheel removal and installation, and ask
him to give you any available manufac-
turer's instructions.
Riding with an improperly secured wheel
can allow the wheel to wobble or fall off
the bicycle, which can cause serious
injury or death. Therefore, it is essen-
tial that you:
1. Ask your dealer to help you make sure
you know how to install and remove
your wheels safely.
2. Understand and apply the correct
technique for clamping your wheel in
place.
3. Each time, before you ride the bike,
check that the wheel is securely clamped.
The clamping action of a correctly
secured wheel must emboss the sur-
faces of the dropouts.
Front Wheel Secondary
Retention Devices
Most bicycles have front forks which uti-
lize a secondary wheel retention device
to reduce the risk of the wheel disengag-

not a substitute for correctly securing your
front wheel.
Secondary retention devices fall into two
basic categories:
1. The clip-on type is a part which the
manufacturer adds to the front wheel hub
or front fork.
2. The integral type is molded, cast or
machined into the outer faces of the front
fork dropouts.
Ask your dealer to explain the particular
secondary retention device on your bike.
Do not remove or disable the secondary
retention device. As its name implies, it
serves as a back-up for a critical adjust-
ment. If the wheel is not secured cor-
rectly, the secondary retention device
can reduce the risk of the wheel disen-
gaging from the fork. Removing or dis-
abling the secondary retention device
may also void the warranty.
Secondary retention devices are not a
substitute for correctly securing your
wheel. Failure to properly secure the
wheel can cause the wheel to wobble
or disengage, which could cause you to
lose control and fall, resulting in serious
injury or death.
Wheels with cam action
systems
There are currently two types of over-cen-
ter cam wheel-retention mechanisms: the
traditional over-center cam (fig. 4-1 ) and
the cam-and-cup system (fig. 4-2 ). Both
use an over-center cam action to clamp
the bike's wheel in place. Your bicycle may
