b. Adjusting the cam-and-cup mechanism

(g. 8b)

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.

3. Removing And Installing Wheels

WARNING

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.

CAUTION

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.

a. Removing a disk 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 Section

4.C g. 11 through 15).

(2) If your bike has cam action front wheel retention,

move the cam lever from the locked or CLOSED

position to the OPEN position (gs. 8a & b).

If your bike has through bolt or bolt-on front

wheel retention, loosen the fastener(s) a few turns

counter-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 . If your front fork

has an integral secondary retention device, and a

traditional cam action system (g. 8a) loosen the

tension adjusting nut enough to allow removing

the wheel from the dropouts. If your front wheel

uses a cam-and-cup system, (g. 8b) 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.

b. Installing a disk brake or rim brake front

wheel

CAUTION

If your bike is equipped with a front 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.
