have a cam-and-cup front wheel retention
system and a traditional rear wheel cam
action system.
Adjusting the traditional cam action
mechanism (fig. 4-1 )
The wheel hub is clamped in place by
the force of the over-center cam pushing
against one dropout and pulling the tension
adjusting nut, by way of the skewer, against
the other dropout. The amount of clamping
force is controlled by the tension adjust-
ing nut. Turning the tension adjusting nut
clockwise while keeping the cam lever from
rotating increases clamping force; turning
it counter-clockwise while keeping the cam
lever from rotating reduces clamping force.
Less than half a turn of the tension adjusting
nut can make the difference between safe
clamping force and unsafe clamping force.
The full force of the cam action is needed
to clamp the wheel securely. Holding
the nut with one hand and turning the
lever like a wing nut with the other hand
until everything is as tight as you can
get it will not clamp a cam action wheel
safely in the dropouts. See also the first
WARNING in this Section on page 25.
Adjusting the cam-and-cup
mechanism (fig. 4-2 )
The cam-and-cup system on your front
wheel will have been correctly adjusted for
your bicycle by your dealer. Ask your dealer
to check the adjustment every six months.
Do not use a cam-and-cup front wheel on
any bicycle other than the one for which
your dealer adjusted it.

Removing and Installing wheels

If your bike is equipped with a hub brake
such as a rear coaster brake, front or
rear drum, band or roller brake; or if
it has an internal gear rear hub, do
not attempt to remove the wheel. The
removal and re-installation of most hub
brakes and internal gear hubs requires
special knowledge. Incorrect removal
or assembly can result in brake or gear
failure, which can cause you to lose
control and fall.
If your bike has a disc brake, exercise
care in touching the rotor or caliper. Disc
rotors have sharp edges, and both rotor
and caliper can get very hot during use.
Removing a disc brake or rim brake
front wheel
1. If your bike has rim brakes, disengage
the brake's quick-release mechanism to
increase the clearance between the tire
and the brake pads (See "Brakes" on page
30, fig. 4-5 through fig. 4-9 ).
2. If your bike has cam action front wheel
retention, move the cam lever from the
locked or CLOSED position to the OPEN
position (fig. 4-1 & fig. 4-2 ). If your bike has
through-bolt or bolt-on front wheel retention,
loosen the fastener(s) a few turns count-
er-clockwise using an appropriate wrench,
lock key or the integral lever.
3. If your front fork has a clip-on type
secondary retention device, disengage it
and go to step (4). If your front fork has an
integral secondary retention device, and
