WARNING: Riding with an improperly secured wheel can allow the wheel
to wobble or fall off the bicycle, which can cause serious injury or death. There-
fore, it is essential 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 surfaces
of the dropouts.
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. 7a) and the cam-and-cup system (fig. 7b). 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.
a. Adjusting the traditional cam action mechanism (fig. 7a)
The wheel hub is clamped in place by the force of the over-center cam pushing against one
dropout and pulling the tension adjusting nut, by way of the skewer, against the other dropout.
The amount of clamping force is controlled by the tension adjusting nut. Turning the tension
adjusting nut clockwise while keeping the cam lever from rotating increases clamping force;
turning it counterclockwise while keeping the cam lever from rotating reduces clamping force.
Less than half a turn of the tension adjusting nut can make the difference between safe clamp-
ing force and unsafe clamping force.
