d. Installing a Quick Release Rear Wheel
WARNING: If your bike is equipped with disk brakes, be careful not to damage the disk, caliper or
brake pads when re-inserting the disk into the caliper. Never activate a disk brake’s control lever unless
the disk is correctly inserted in the caliper.
IMPORTANT: Never touch brake rotor or pads, as grease, oil or any other foreign substance can
contaminate the brake system and decrease the brakes efficiency, or cause them not to work
all-together.
1. Shift the rear derailleur to its outermost position
2. Pull the derailleur body back with your right hand.
3. Move the quick-release lever to the OPEN position (see fig. 6). The lever
should be on the side of the wheel opposite the derailleur and freewheel
sprockets.
4. Put the chain on top of the smallest freewheel sprocket. Then, insert the
wheel into the frame dropouts and pull it all the way in to the dropouts.
5. Tighten the quick-release adjusting nut until it is finger tight against the
frame dropout; then swing the lever toward the front of the bike until it
is parallel to the frame’s chainstay or seatstay and is curved toward the
wheel (fig. 7b).
To apply enough clamping force, you should have to wrap your fingers
around a frame tube for leverage, and the lever should leave a clear imprint
in the palm of your hand.
WARNING: Securely clamping the wheel takes considerable force. If you can fully close the quick
release without wrapping your fingers around the seatstay or chainstay for leverage, and the lever
does not leave a clear imprint in the palm of your hand, the tension is insufficient. Open the lever; turn
the tension-adjusting nut clockwise a quarter turn; then try again.
The rear wheel must be secured to the bicycle frame with sufficient force so that it cannot be pulled
forward by the chain, even under the greatest pedaling force. If the wheel moves under
pedaling force, the tire can touch the frame, which can cause you to loose control and fall.
6. If the lever cannot be pushed all the way to a position parallel to the
chainstay or seatstay tube, return the lever to the OPEN position. Then
turn the adjusting nut counterclockwise one-quarter turn and try tightening
again.
7. Push the rear derailleur back into position.
8. Re-engage the brake quick-release mechanism to restore correct brake-
pad-to-rim clearance; 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.
