2. WHEELS WITH CAM ACTION SYSTEMS:
There are two types of wheel retention mechanisms that utilize a cam
action system: the traditional over-center cam and the cam-and-cup
system. Both of these systems employ an over-center cam action to
securely clamp the bike's wheels in place. It is possible that your bicycle is
equipped with a cam-and-cup system for the front wheel and a cam
action system for the rear wheel. To ensure proper understanding and
operation of these systems, it is advisable to consult the manufacturer's
instructions provided by your dealer.
3. REMOBING AND INSTALLING WHEELS
B. ADJUSTING THE CAM-AND-CUP MECHANISM:
A. ADJUSTING THE TRADITIONAL CAM ACTION MECHANISM:
Ensure that the skewer is located against one dropout and that the
lever is pulling evenly over the skewer against the other dropout.
The clamping force is controlled by the tension adjusting nut.
Turning the nut clockwise while preventing the cam lever from
rotating increases clamping force, while turning it counterclock-
wise reduces clamping force. Even a small adjustment, less than
half a turn of the tension adjusting nut, can make a significant
difference in safely clamping the wheel.
The full force of the cam action is necessary to securely
clamp the wheel. Simply holding the nut with one hand and
turning the lever like a wing nut with the other hand will not
provide a safe clamp for a cam action wheel in the dropouts.
WARNING
The cam-and-cup system on your front wheel should have
been correctly adjusted by your dealer for your specific
bicycle. It is recommended to have your dealer check this
adjustment every six months. Do not use a cam-and-cup
front wheel on any other bicycle than the one for which it
was adjusted by your dealer.
WARNING
A. REMOVING A DISK BRAKE OR RIM BRAKE FRONT WHEEL:
1. For bikes with rim brakes, disengage the brake's quick-release
mechanism to create more space between the tire and brake pads.
2. If your bike has a cam action front wheel retention system, move the
cam lever from the locked or closed position to the open position. If
your bike has a through bolt or bolt-on front wheel retention, loosen
the fastener using an appropriate tool.
3. If your front fork has a clip-on type secondary retention device,
disengage it. If your front fork has an integral secondary retention
device, and a traditional cam action system, loosen the tension
adjusting nut to allow for wheel removal. If your front wheel uses a
cam-and-cup system, squeeze the cup and cam together while
removing the wheel.
4. In some cases, you may need to tap the top of the wheel with your
hand to release it from the front fork.
B. INSTALLING A DISK BRAKE OR RIM BRAKE FRONT WHEEL:
1. If your bike is equipped with a front disk brake, be cautious not to
damage the disk, caliper, or brake pads when inserting the disk into
the caliper. Only activate the brake lever when the disk is correctly
inserted in the caliper.
2. For bikes with a cam action front wheel retention system, move the
cam lever away from the wheel, into the open position. If your bike
has a through bolt
3. If you have a traditional cam action mechanism, position the cam
lever in the closed position, parallel to the fork blade and curved
toward the wheel. Apply enough clamping force by wrapping your
fingers around the fork blade for leverage, ensuring the lever leaves a
clear imprint in your hand.
4. With a through bolt or bolt-on system, tighten the fasteners
according to the recommended torque specifications for your
specific bike model.
5. If using a traditional cam action system and the lever cannot be pushed
all the way to a position parallel to the fork blade, return the lever to the
open position. Then, turn the tension adjusting nut counterclockwise by
one-quarter turn and attempt to tighten the lever again.
