cup front wheel on any bicycle other than the one for which your Dealer adjusted it.
6.A.1. Removing and Installing the Front Wheels
WARNING: If your bike is equipped with a hub brake, drum, band or roller brake, do not attempt to
remove the wheel. The removal and re-installation of most hub brakes requires special knowledge. Incorrect
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.
Removing a Front Wheel Disc Brake
(1) If your bike has cam action front wheel retention, move the cam lever from the locked or CLOSED position
to the OPEN position (fig. 16, 17). 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.
(2) 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 (fig. 16)
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. 17) 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.
Installing a Front Wheel Disc Brake
CAUTION: If your bike is equipped with a front disc brake, be careful not to damage
the disc, caliper or brake pads when re-inserting the disc into the caliper. Never activate a
disc brake's control lever unless the disc is correctly inserted in the caliper (6.C).
(1) If your bike has cam action front wheel retention, move the cam lever so that
it curves away from the wheel (fig. 17). 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 one, should be on the rider's left side
of the bicycle (fig. 16, 17). 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 finger tight against
the fork dropout (fig. 16). If you have a cam-and-cup system: the nut and cup (fig. 17) will have
snapped into the recessed area of the fork dropouts and no adjustment should be required.
(4) While pushing the wheel firmly 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 (fig. 16, 17). 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 fingers 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
specifications in Appendix C 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.
(5) With a through-bolt or bolt-on system, tighten the fasteners to the torque
specifications in Appendix C or the hub manufacturer's instructions.
WARNING: Securely clamping the wheel with a cam action retention device takes considerable force.
If you can fully close the cam lever without wrapping your fingers around the fork blade for leverage, the
lever does not leave a clear imprint in the palm of your hand, and the serrations on the wheel fastener
do not emboss the surfaces of the dropouts, the tension is insufficient. Open the lever; turn the tension
adjusting nut clockwise a quarter turn; then try again. See also the first WARNING in this Section.
(6) If you disengaged the brake quick-release mechanism, re-engage
it to restore correct brake pad-to-rim clearance.
(7) Spin the wheel to make sure that it is centered in the frame and clears the brake pads;
then squeeze the brake lever and make sure that the brakes are operating correctly.
