// MANUAL
1. 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:
i. 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.
ii. With a through-bolt or bolt-on system, tighten the fasteners to the torque specications
in Appendix E 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 ten-
sion adjusting nut counterclockwise one-quarter turn and try tightening the lever again.
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 ngers
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 insucient. Open the lever; turn the tension adjusting nut clockwi-
se a quarter turn; then try again. See also the rst WARNING in this Section, p. 19.
5. If you disengaged the brake quick-release mechanism in 3. a. 1) above, re-engage it to
restore correct brake pad-to-rim clearance.
6. 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 PROPAIN or 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, gs. 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 (g.
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.
