PART I
(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 position (fig. 8b). With
a through bolt or bolt on mechanism, loosen the
fastener(s) with an appropriate wrench, lock lever
or integral 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.
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.
WARNING
SECURELY CLAMPING THE WHEEL WITH
A CAM ACTION RETENTION DEVICE TAKES
CONSIDERABLE FORCE.
If you can fully close the cam lever without
wrapping your fingers around the seat stay or
chain stay 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
insufficient. Open the lever; turn the tension
adjusting nut clockwise a quarter turn; then try
again.
