(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 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.
3. Removing and Installing Bolt-On Wheels
a. Removing a Bolt-On Front Wheel
(1) If your bike has rim brakes, disengage the brake's quick-release mechanism
to open the clearance between the tire and the brake pads (see Section 4.C, figs.
11 through 15).
(2) Using a correct size wrench, loosen the two axle nuts.
(3) If your front fork has a clip-on type secondary retention device, disengage
it and go to he next step. If your front fork has an integral secondary retention
device, loosen the axle nuts enough to allow wheel removal; then go to the next
step.
(4) Raise the front wheel a few inches off the ground and tap the top of the wheel
with the palm of your hand to knock the wheel out of the fork ends.
