Nirve Cruiser - Secondary Retention Devices; Wheels with Cam Action Systems

18
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 (g. 8a) and the cam-and-cup
system (g. 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
