Secondary Retention Devices; Wheels With Cam Action Systems - Priority Bicycle Owner's Manual

Your bicycle may be equipped with a different securing method for the front wheel than for the rear wheel. Discuss the wheel
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 manufacturer's
instructions.
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. Therefore, 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. 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.
