need to tap the top of the wheel with the palm of your hand to release the wheel from the front fork.

d. Installing a WTB Rear Wheel

CAUTION: 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 (fig. 1). 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 LaserDisc Single Duty hub, 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 LaserDisc Single Duty 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. 1). 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 seat stay or chain stay for leverage, and the lever should leave a clear imprint in the palm of your hand.

(7)With a Single Duty hub, tighten the fasteners to 10 Nm (90 in. lbs) torque.

NOTE: If, on a 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.

(8)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.

e.Removing a WTB 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 a single-speed bike with a WTB LaserDisc Single Duty hub, go to step (3) below.

(2)On a derailleur gear system, pull the derailleur body back with your right hand.

(3)With a cam action system, move the quick-release lever to the OPEN position (fig. 1). With the Single Duty hub, loosen the fasteners with a 5mm hex wrench (fig. 2); then push the wheel forward or down far enough to be able to remove the chain from the rear sprocket.

(4)Lift the rear wheel off the ground a few inches and remove it from the rear dropouts.
