INSTALLING A QUICK RELEASE FRONT WHEEL
CAUTION: Your OHM bicycle is equipped with disc brakes.
Be very careful not to damage the disc, caliper or brake pads
when re-inserting the disc into the caliper. Never activate a disc
brakes control lever unless the disc is correctly inserted in the
caliper (see also Section 4.3).
a. Move the quick release lever so that it curves away from the wheel
(see Fig 4.1.2). This is the OPEN position.
b. With the steering fork facing forward, insert the wheel between
the fork blades so that the axle seats firmly at the tip of the slots,
which are at the tips of the fork blades – the fork dropouts. The
quick release lever should be on the left side of the bicycle
(see Fig 4.1.2).
c. Holding the quick release lever in the OPEN position with your
right hand, tighten the tension adjusting nut with your left hand until
finger tight against the fork dropout (see Fig 4.1.1).
d. 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, move the quick release lever upwards and swing it into the
CLOSED position (see Fig 4.1.2). 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.
CAUTION: 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.
e. 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.
f. Re-engage the brake quick release mechanism to restore correct
brake pad to disc clearance; spin the wheel to make sure that it is
centered in the frame and clears the disc, then squeeze the brake
lever and make sure that the brakes are operating correctly.
WARNING: Secondary retention devices are not a
substitute for correct quick release adjustment. Failure to
properly adjust the quick release mechanism can cause the
wheel to wobble or disengage, which could cause you to lose
control and fall, resulting in serious injury or death.
