(5) Lift the rear wheel off the ground a few
inches and remove it from the rear dropouts.
d. Installing a disk brake or rim brake
rear wheel
CAUTION
If your bike is equipped with a rear disk brake,
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) With a cam action system, move the cam
lever to the OPEN position (see fig. 8 a & b).
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.
(4) Then, insert the wheel into the frame
dropouts and pull it all the way in to the
dropouts.
(5) On a single speed or an internal gear hub,
replace the chain on the chainring; pull the
wheel back in the dropouts so that it is
straight in the frame and the chain has about
1/4 inches of up-and-down play.
(6) With a cam action system, move the cam
lever upwards and swing it into the CLOSED
position (fig. 8 a & b). The lever should now
be parallel to the seat stay or chain stay and
curved toward the wheel. To apply enough
clamping force, you should have to wrap
your fingers around the seat stay or
chainstay for leverage, and the lever should
leave a clear imprint in the palm of your
hand.
(7) With a through-bolt or bolt-on system,
tighten the fasteners to the torque
specifications in PART II “Tightening
Torques” or the hub manufacturer’s
instructions.
NOTE: If, on a traditional cam action system, the
lever cannot be pushed all the way to a position
parallel to the seat stay or chain stay, return the
lever to the OPEN position. Then turn the tension
adjusting nut counterclockwise one-quarter turn
and try tightening the lever again.
