1. Front Wheel Secondary
Retention Devices
Most bicycles have front forks which utilize a
secondary wheel retention device to reduce the
risk of the wheel disengaging from the fork if the
wheel is incorrectly secured. Secondary
retention devices are not a substitute for
correctly securing your front wheel.
Secondary retention devices fall into two basic
categories:
a. The clip-on type is a part which the
manufacturer adds to the front wheel hub or
front fork.
b. 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.
WARNING
Do not remove or disable the secondary
retention device.
As its name implies, it serves as a back-up for
a critical adjustment. If the wheel is not
secured correctly, the secondary retention
device can reduce the risk of the wheel
disengaging from the fork. Removing or
disabling 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 loose control and
fall, resulting in serious injury or death.
2. Wheels with cam action
systems
There are currently two types of over-center cam
wheel retention mechanisms: the traditional
over-center cam (fig. 8a) and the cam-and-cup
system (fig. 8b). Both use an over-center cam
action to clamp the bike’s wheel in place. Your
bicycle may have a cam-and-cup front wheel
retention system and a traditional rear wheel
cam action system.
