Wheels
a traditional cam action system (fi g. 4-1 )
loosen the tension adjusting nut enough to
allow removing the wheel from the dropouts.
If your front wheel uses a cam-and-cup sys-
tem, (fi g. 4-2 ) squeeze the cup and cam
lever together while removing the wheel.
No rotation of any part is necessary with
the cam-and-cup system.
You may need to tap the top of the wheel
with the palm of your hand to release the
wheel from the front fork.
Installing a disc brake or rim brake
front wheel
If your bike is equipped with a front 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.
See also “Brakes” on page 30.
1.
If your bike has cam action front
wheel retention, move the cam lever so
that it curves away from the wheel (fi g. 4-2 ).
This is the OPEN position. If your bike has
through-bolt or bolt-on front wheel retention,
go to the next step.
2.
With the steering fork facing forward,
insert the wheel between the fork blades
so that the axle seats fi rmly at the top of
the fork dropouts. The cam lever, if there
is one, should be on rider’s left side of the
bicycle (fi g. 4-1 & fi g. 4-2 ). If your bike has
a clip-on type secondary retention device,
engage it.
3.
If you have a traditional cam action
mechanism: holding the cam lever in the
ADJUST position with your right hand,
tighten the tension adjusting nut with your
left hand until it is fi nger tight against the
fork dropout (fi g. 4-1 ). If you have a cam-
and-cup system: the nut and cup (fi g. 4-2 )
will have snapped into the recessed area
of the fork dropouts and no adjustment
should be required.
4.
While pushing the wheel fi rmly to the
top of the slots in the fork dropouts, and
at the same time centering the wheel rim
in the fork:
a) With a cam action system, move the
cam lever upwards and swing it into the
CLOSED position (fi g. 4-1 & fi g. 4-2 ). 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 fi ngers around the fork
blade for leverage, and the lever should
leave a clear imprint in the palm of your
hand.
b) With a through-bolt or bolt-on system,
tighten the fasteners to the torque specifi -
cations in ”Fastener Torque Specifi cations”
on page 74 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 fork
blade, return the lever to the OPEN posi-
tion. Then turn the tension adjusting nut
counter-clockwise one-quarter turn and
try tightening the lever again.

tighten the fasteners to the torque specifi -
cations in “Fastener Torque Specifi cations”
