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 g. 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 (gs. 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. If your front fork has an integral secondary retention device, and a traditional
cam action system (g. 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, (g. 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 (g. 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 rmly at the top of the fork dropouts. The cam lever,
if there is one, should be on rider’s left side of the bicycle (g. 8a & b). If your
bike has a clip-on type secondary retention device, engage it.
(3) If you have a traditional cam action mechanism: holding the cam lever
in the ADJUST position with your right hand, tighten the tension adjusting nut
with your left hand until it is nger tight against the fork dropout (g. 8a). If you
have a cam-and-cup system: the nut and cup (g. 8b) will have snapped into the
recessed area of the fork dropouts and no adjustment should be required.
(4) While pushing the wheel rmly to the top of the slots in the fork dropouts, and
at the same time centering the wheel rim in the fork:
(a) With a cam action system, move the cam lever upwards and swing it
into the CLOSED position (g. 8a & b). The lever should now be parallel to the
fork blade and curved toward the wheel. To apply enough clamping force, you
should have to wrap your ngers around the fork blade for leverage, and the
lever should leave a clear imprint in the palm of your hand.
(b) With a through-bolt or bolt-on system, tighten the fasteners to the torque
specications in Appendix D or the hub manufacturer’s instructions.
NOTE: If, on a traditional cam action system, the lever cannot be pushed all the
way to a position parallel to the fork blade, return the lever to the OPEN position.
Then turn the tension adjusting nut counterclockwise one-quarter turn and try
tightening the lever again.
