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 clockwise a quarter turn; then try again.
(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 centred 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 stockist 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 o the ground a few inches and remove it from the rear
dropouts.
d. Installing a disk brake or rim brake rear wheel
WARNING: 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. 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 bikes, 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 chain-ring;
pull the wheel back in the dropouts so that it is straight in the frame and the
chain has about 6mm (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. 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 anti-clockwise a 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 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 insucient.
Open the lever; turn the tension adjusting nut clockwise a quarter turn; then try
again. See also the rst WARNING in this section.
(8) If you disengaged the brake quick-release mechanism in 3. c. (2) above, re-
engage it to restore correct brake pad-to-rim clearance.
(9) Spin the wheel to make sure that it is centred in the frame and clears the brake
pads; then squeeze the brake lever and make sure that the brakes are operating
correctly.
B. Seat Post Cam Action Clamp
Some bikes are equipped with a cam action seat post binder. The seat post cam
action binder works exactly like the traditional wheel cam action fastener (Section
4.A.2) While a cam action binder looks like a long bolt with a lever on one end and a
nut on the other, the binder uses an over-centre cam action to rmly clamp the seat
post (see g. 8).
WARNING: Riding with an improperly tightened seat post can allow the saddle to
turn or move and cause you to lose control and fall. Therefore:
1. Ask your stockist to help you make sure you know how to correctly clamp your
seat post.
2. Understand and apply the correct technique for clamping your seat post.
3. Before you ride the bike, rst check that the seat post is securely clamped.
