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 disc 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.
d. Installing a Disc Brake or Rim Brake Rear Wheel
CAUTION:
If your BIke Is equIpped wIth a rear 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.
(1) With a cam action system, move the cam lever to the OPEN position (see g. 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 a single-speed bike, 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 (g. 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
ngers around the fork blade for leverage, and the lever should leave a clear imprint in
the palm of your hand.
(7) 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 seat stay or chain stay, return the lever to the OPEN position. Then turn the tension
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 fIngers around the seat stay or chaIn stay 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, p. 17.
