(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.

(5) With a through-bolt or bolt-on system, tighten the fasteners to the torque specifications
in Appendix D or the hub manufacturer’s instructions.
(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 Disc 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).
