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 whilst keeping the cam
lever from rotating increases clamping force;
turning it anticlockwise whilst 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 reduce the
risk of the wheel disengaging from the fork 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:
1 The clip-on type is an oval washer with a tab,
(fig. 9) which the manufacturer adds to the
front wheel hub. The tabs must be located in
the holes or slots at the ends of the fork legs,
before tightening the wheel nuts.
2 The integral type is a recess that is moulded,
cast or machined into the outer faces of the
front fork dropouts.

Release Wheels
a. Removing A Quick Release
Front Wheel
CAUTION: If your bike has a disc front
brake, exercise care in touching it.
Discs have sharp edges and can get very hot
during use.
1 If your bike has rim brakes, disengage the
brake's quick-release mechanism to increase
the clearance between the tyre and brake
blocks (See Section 4.C fig.14 through to 18).
2 Move the wheel's quick-release lever from the
locked or CLOSED position to the OPEN
position (figs. 10a & b).
3 If your front fork does not have a secondary
retention device go to step (5).

Need assistance?
Ask your local 13 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 quick release is not
adjusted 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 correct quick release
adjustment. Failure to properly adjust the
quick release mechanism can cause the
wheel to wobble or disengage, which could
cause you to loose control and fall, resulting
in serious injury or death.
