WARNING: 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 a cam action wheel safely
in the dropouts. See also the first WARNING in this
Section, p. 16.
b. Adjusting the cam-and-cup mechanism (fig. 8b)
The cam-and-cup system on your front wheel will have
been correctly adjusted for your bicycle by your dealer.
Ask your dealer to check the adjustment every six months.
Do not use a cam-and-cup front wheel on any bicycle
other than the one for which your dealer adjusted it.
3. Removing and Installing wheels
WARNING: If your bike is equipped with a hub
brake such as a rear coaster brake, front or rear drum,
band or roller brake; or if it has an internal gear rear
hub, do not attempt to remove the wheel. The removal
and re-installation of most hub brakes and internal
gear hubs requires special knowledge. Incorrect re-
moval or assembly can result in brake or gear failure,
which can cause you to lose control and fall.
CAUTION: If your bike has a disc brake, exercise
care in touching the rotor or caliper. Disc rotors have
sharp edges, and both rotor and caliper can get very
hot during use.
a. Removing a disk brake or rim brake Front Wheel
(1) If your bike has rim brakes, disengage the brake's
quick-release mechanism to increase the clearance
between the tire and the brake pads (See Section 4.C
fig. 11 through 15).
(2) If your bike has cam action front wheel retention,
move the cam lever from the locked or CLOSED position
to the OPEN position (figs. 8a & b). If your bike has
through bolt or bolt-on front wheel retention, loosen
the fastener(s) a few turns counter-clockwise using an
appropriate wrench, lock key or the integral lever.
(3) If your front fork has a clip-on type secondary
retention device, disengage it and go to step (4). If your
front fork has an integral secondary retention device,
and a traditional cam action system (fig. 8a) loosen the
tension adjusting nut enough to allow removing the wheel
from the dropouts. If your front wheel uses a cam-and-
cup system, (fig. 8b) squeeze the cup and cam lever
together while removing the wheel. No rotation of any
part is necessary with the cam-and-cup system.
You may need to tap the top of the wheel with the palm
of your hand to release the wheel from the front fork.
b. Installing a disk brake or rim brake Front Wheel
CAUTION: If your bike is equipped with a front disk
brake, be careful not to damage the disk, caliper or
brake pads when re-inserting the disk into the caliper.
Never activate a disk brake's control lever unless
the disk is correctly inserted in the caliper. See also
Section 4.C.
(1) If your bike has cam action front wheel retention,
move the cam lever so that it curves away from the
wheel (fig. 8b). This is the OPEN position. If your bike has
through bolt or bolt-on front wheel retention, go to the
next step.
(2) With the steering fork facing forward, insert the wheel
between the fork blades so that the axle seats firmly at
the top of the fork dropouts. The cam lever, if there is
