Wheels
Securely clamping the wheel with a cam
action retention device takes consid-
erable force. If you can fully close the
cam lever without wrapping your fi ngers
around the fork blade 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
insuffi cient. Open the lever; turn the ten-
sion adjusting nut clockwise a quarter
turn; then try again. See also the fi rst
WARNING in this Section on page 25.
6.
If you disengaged the brake quick-re-
lease mechanism before removing the
wheel, as described above, re-engage it to
restore correct brake pad-to-rim clearance.
7.
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 oper-
ating correctly.
Removing a disc brake or rim brake
rear wheel
1.
If you have a multi-speed bike with a
derailleur gear system: shift the rear derail-
leur to high gear (the smallest, outermost
rear sprocket).
If you have an internal gear rear hub, con-
sult your dealer or the hub manufacturer’s
instructions before attempting to remove
the rear wheel.
If you have a single-speed bike with rim
or disc brake, go to step (4) below.
2.
If your bike has rim brakes, disengage
the brake’s quick-release mechanism to
increase the clearance between the wheel
rim and the brake pads (see “Brakes” on
page 30, fi g. 4-5 through fi g. 4-9 ).
3.
On a derailleur gear system, pull the
derailleur body back with your right hand.
4.
With a cam action mechanism, move
the quick-release lever to the OPEN posi-
tion (fi g. 4-2 ). With a through-bolt or bolt
on mechanism, loosen the fastener(s) with
an appropriate wrench, lock lever or inte-
gral lever; then push the wheel forward
far enough to be able to remove the chain
from the rear sprocket.
5.
Lift the rear wheel off the ground a few
inches and remove it from the rear dropouts.
Installing a disc brake or rim brake
Rear Wheel
If your bike is equipped with a rear disc
brake, be careful not to damage the rotor,
caliper or brake pads when re-inserting
the rotor into the caliper. Never activate
a disc brake’s control lever unless the
rotor is correctly inserted in the caliper.
1.
With a cam action system, move the
cam lever to the OPEN position (see fi g.
4-1 & fi g. 4-2 ). 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 single-speed, 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.
