6. How Things Work
It’s important to your performance, enjoyment and safety to understand how things work on your bicycle. Even if you’re an experienced
bicyclist, don’t assume that the way things work on your new bike is the same as how they work on older bikes. Be sure to read and to
understand this section of the Manual. If you have even the slightest doubt as to whether you understand something, talk to your dealer.
A. Wheel Quick Release
WARNING: Riding with an improperly adjusted wheel quick release can allow the wheel to wobble or disengage from the bicycle, causing
damage to the bicycle, and serious injury or death to the rider. 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 with a quick release.
3. Each time, before you ride the bike, check that the wheel is securely clamped.
Invented in the 1930s to allow quick, easy wheel removal without the need for tools, the bicycle wheel quick release has become stan-
dard equipment on most recreational, sports and competition bicycles. While it looks like a long bolt with a lever on one end and a nut on
the other, the wheel quick release uses a cam action to clamp the bike’s wheel in place. Because of its adjustable nature, it is critical that
you understand how it works and how to use it properly.
CAUTION: The full force of the cam action is needed to clamp the wheel securely. 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.
1. 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.
NOTE: Once the quick release is installed in the hub axle by the manufacturer or the dealer, it never needs to be removed unless the
hub itself requires servicing. If the hub requires servicing, consult your dealer.
2. Front Wheel Secondary Retention Devices
Many bicycles have front forks which utilizes 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.
