WARNING in this Section, p. 18.
(6) If you disengaged the brake quick-release mechanism in 3. a. (1) above,
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.
c. Removing a disk brake or rim brake Rear Wheel
(1) If you have a multi-speed bike with a derailleur gear system: shift the rear
derailleur to high gear (the smallest, outermost rear sprocket).
If you have an internal gear rear hub, consult your dealer or the hub
manufacturer’s instructions before attempting to remove the rear wheel.
If you have a single-speed bike with rim or disk brake, go to step (4) below.
(2) If your bike has rim brakes, disengage the brake’s quick-release
mechanism to increase the clearance between the wheel rim and the brake pads
(see Section 4.C, figs. 11 through 15).
(3) On a derailleur gear system, pull the derailleur body back with your right
hand.
(4) With a cam action mechanism, move the quick-release lever to the
OPEN position (fig. 8b). With a through bolt or bolt on mechanism, loosen the
fastener(s) with an appropriate wrench, lock lever or integral lever; then push the
wheel forward far enough to be able to remove the chain from the rear sprocket.
(5) Lift the rear wheel off the ground a few inches and remove it from the rear
dropouts.
d. Installing a disk brake or rim brake Rear Wheel
CAUTION: If your bike is equipped with a rear 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.
(1) With a cam action system, move the cam lever to the OPEN position (see
fig. 8 a & b). The lever should be on the side of the wheel opposite the derailleur
and freewheel sprockets.
(2) On a derailleur bike, make sure that the rear derailleur is still in its
outermost, high gear, position; then pull the derailleur body back with your right
hand. Put the chain on top of the smallest freewheel sprocket.
(3) On single-speed, remove the chain from the front sprocket, so that you
have plenty of slack in the chain. Put the chain on the rear wheel sprocket.
(4) Then, insert the wheel into the frame dropouts and pull it all the way in to
the dropouts.
(5) On a single speed
or an internal gear hub, replace the chain on the
chainring; pull the wheel back in the dropouts so that it is straight in the frame
and the chain has about 1/4 inches of up-and-down play.
(6) With a cam action system, move the cam lever upwards and swing it into
the CLOSED position (fig. 8 a & b). The lever should now be parallel to the seat
stay or chain stay 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
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 one, should be on rider’s left side of the bicycle (fig. 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 finger tight against the fork dropout (fig. 8a). If you
have a cam-and-cup system: the nut and cup (fig. 8b) 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. 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 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 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.
D (6) With a through-bolt or bolt-on system, tighten the fasteners to the torque
specifications in Appendix D 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
