WARNING: The full force of the cam action is needed to clamp the wheel se-
curely. 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.
b. Adjusting the cam-and-cup mechanism (fig. 7b)
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-installa-
tion of most hub rakes and internal gear hubs requires special knowledge. Incor-
rect removal 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. 10 through 14).
(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. 7a & 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. 7a) 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. 7b) 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 reinserting 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.
