NOTE: If you have a mountain bike equipped
with through axle front or rear wheels, make sure
that your dealer has given you the manufacturer's
instructions, and follow those when installing or
removing a through axle wheel. If you don't know
what a through axle is, ask your dealer.
The wheel quick release uses a cam action to
clamp the bike's wheel in place (see fig. 6).
Because of its adjustable nature, it is critical
that you understand how it works, how to use it
properly, and how much force you need to apply
to secure the wheel.

Holding the nut with one hand and turning the
lever like a wing nut with the other hand until
everything is as tight as you can get it will not
clamp the wheel safely in the dropouts.

a. adjusting the Quick Release
mechanism
The wheel hub is clamped in place by the force
of the quick release 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 clamping
force and unsafe clamping force.
b. front Wheel secondary Retention
devices
Most bicycles have front forks which utilize a
secondary wheel retention device to keep the
wheel from disengaging if the quick release is
incorrectly adjusted. Secondary retention devices
are not a substitute for correct quick release
adjustment.
Secondary retention devices fall into two basic
categories:
. The clip-on type is a part which the
manufacturer adds to the front wheel hub or
front fork.
. 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.
