1. Adjusting the quick release mechanism (see Fig. 11, opposite)
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 keep- ing 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 manu- facturer 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 utilize a secondary wheel retention device to keep the wheel from disengaging if the quick release is incor- rectly adjusted. Secondary retention devices are not a substitute for
correct quick release adjustment.
