the wheel rim in the fork, move the quick-release lever
upwards and swing it into the CLOSED position (fig.
6 & 7a). 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.
!
WARNING: Securely clamping the wheel takes
considerable force. If you can fully close the quick
release without wrapping your fingers around the fork
blade 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.
(5) If 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.
(6) 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.
c. Removing a Quick Release Rear Wheel
(1) Shift the rear derailleur to high gear (the smallest,
outermost rear sprocket).
(2) If your bike has rim brakes, disengage the brake's
quick-release mechanism to open the clearance
between the wheel rim and the brake pads (see Section
4.C, figs. 11 through 15).
(3) Pull the derailleur body back with your right hand.
(4) Move the quick-release lever to the OPEN position
(fig. 7b).
(5) Lift the rear wheel off the ground a few inches
and, with the derailleur still pulled back, push the
wheel forward and down until it comes out of the
rear dropouts.
d. Installing a Quick Release Rear Wheel
NOTE: 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.
(1) Make sure that the rear derailleur is still in its
outermost, high gear, 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. 7a & fig. 8). To apply enough clamping force,
you should have to wrap your fingers around a frame
