4. Tech
It’s important to your safety, performance and enjoyment to understand how things work on your bicycle. If you
have even the slightest doubt as to whether you understand something in this section of the Manual, talk to your
dealer.
A. Wheels
1. Wheel Quick Release Description. 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.
2. Adjusting the Quick Release Mechanism.
The wheel hub is clamped in place by the
force of the quick release cam pushing against
fig. 6
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.
3. 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. Ask your dealer to explain the
particular secondary retention device on your bike.
