1. Before you start  
GENERAL WARNING:  
The fact that you selected one or more WTB components for your bike indicates that you are  
probably a rider of above average experience; but don’t allow that to lull you into complacency. No  
matter how experienced you are as a cyclist, do not fail to read this WARNING or to carefully follow the  
instructions below.  
Technological advances have made bicycles and bicycle components more complex, and the pace  
of innovation is increasing. Many bicycle component installation, service and repair tasks require  
special knowledge and tools. Improper installation, adjustment or service may result in damage to the  
component or component failure.  
All WTB products should be installed by a qualified bicycle mechanic using appropriate  
professional tools. WTB assumes no liability for products which are improperly installed, assembled or  
configured.  
When installing WTB components in conjunction with another manufacturer’s components, you  
should always follow that manufacturer’s instructions for their components and WTB’s for WTB  
components. If there is a conflict, ask your dealer to help you resolve it. WTB assumes no liability for  
damage caused by installing other manufacturers’ products.  
After any installation, adjustment or repair to your bicycle or components, test your work by taking  
a test ride in a controlled environment, away from cars, other cyclists, obstacles or other hazards.  
Failure to follow these instructions can result in component failure. Component failure can cause  
you to lose control of the bicycle and fall, leading to serious injury or death.

dropout. The amount of clamping force is controlled by the tension adjusting nut. Turning the tension adjusting  
nut clockwise while keeping the open cam lever from rotating increases clamping force; turning it counter-  
clockwise while keeping the open 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.  
WARNING: 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.  
b. Installing a WTB Front Wheel with over-center cam action quick release  
CAUTION: Be careful not to damage the disc, caliper or brake pads when re-inserting the disc into  
the caliper. Never activate a disc brake’s control lever unless the disc is correctly inserted in the  
caliper.  
(1) Move the cam lever so that it curves away from the wheel (fig.1). This is the OPEN position.  
(2) With the steering fork facing forward, insert the wheel between the fork blades so that the axle seats  
firmly at the top of the fork dropouts. The cam lever should be on rider’s left side of the bicycle (fig. 1).  
(3) Holding the cam lever in the ADJUST position with your right hand, tighten the tension adjusting nut with  
your left hand until it is finger tight against the fork dropout (fig. 1).  
(4) While pushing the wheel firmly to the top of the slots in the fork dropouts, and at the same time centering  
the wheel rim in the fork, move the cam lever upwards and swing it into the CLOSED position (fig. 1). 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 fingers around the fork blade for leverage, and the lever should leave a clear imprint  
in the palm of your hand.  
NOTE: If 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 one-quarter turn and try tightening the  
lever again.  
Securely clamping the wheel with a cam action retention device takes considerable  
WARNING:  
force. If you can fully close the cam lever without wrapping your fingers around the fork blade 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.  
(5) Spin the wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the  
brake lever and make sure that the brakes are operating correctly.  
c. Removing a WTB Front Wheel with over-center cam action quick release  
CAUTION: Disc rotors have sharp edges, and both rotor and caliper can get very hot during use.  
Exercise care in touching the rotor or caliper.  
(1) Move the cam lever from the locked or CLOSED position to the OPEN position (fig. 1).  
(2) Loosen the tension adjusting nut enough to allow removing the wheel from the fork dropouts. You may

need to tap the top of the wheel with the palm of your hand to release the wheel from the front fork.  
d. Installing a WTB Rear Wheel  
CAUTION: Be careful not to damage the disc, caliper or brake pads when re-inserting the disc into  
the caliper. Never activate a disc brake’s control lever unless the disc is correctly inserted in the  
caliper.  
(1) With a cam action system, move the cam lever to the OPEN position (fig. 1). 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 a LaserDisc Single Duty hub, 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 LaserDisc Single Duty 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. 1).  
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 fork blade seat stay or chain stay for  
leverage, and the lever should leave a clear imprint in the palm of your hand.  
(7) With a Single Duty hub, tighten the fasteners to 10 Nm (90 in. lbs) torque.  
NOTE: If, on a 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.  
Securely clamping the wheel with a cam action retention device takes considerable  
WARNING:  
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.  
(8) Spin the wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the  
brake lever and make sure that the brakes are operating correctly.  
e. Removing a WTB Rear Wheel  
(1) If you have a multi-speed bike with a derailleur gear system: shift the rear derailleur to high gear (the  
smallest, outermost rear sprocket).  
If you have a single-speed bike with a WTB LaserDisc Single Duty hub, go to step (3) below.  
(2) On a derailleur gear system, pull the derailleur body back with your right hand.  
(3) With a cam action system, move the quick-release lever to the OPEN position (fig. 1). With the Single  
Duty hub, loosen the fasteners with a 5mm hex wrench (fig. 2); then push the wheel forward or down far  
enough to be able to remove the chain from the rear sprocket.  
(4) Lift the rear wheel off the ground a few inches and remove it from the rear dropouts.

3. Maintenance and Repair  
WARNING:  
Many bicycle component installation, service and repair tasks require special knowledge and tools.  
Do not begin any installation, adjustments or service on your bicycle until you have learned from your  
dealer how to properly complete it. Improper installation, configuration, adjustment or service may  
result in damage to the component or component failure. Component failure can cause you to lose  
control and fall.  
BPSA-OM9-5  
Like any mechanical device, a bicycle and its components are subject to wear and stress. Different  
materials and mechanisms wear or fatigue from stress at different rates and have different life cycles.  
If a component’s life cycle is exceeded, the component can suddenly and catastrophically fail, causing  
serious injury or death to the rider. Creaks, scratches, cracks, fraying and discoloration are signs of  
stress-caused fatigue and indicate that a part is at the end of its useful life and needs to be replaced.  
While the materials and workmanship of your bicycle or of individual components may be covered by a  
warranty for a specified period of time by the manufacturer, this is no guarantee that the product will  
last the term of the warranty. Product life is often related to the kind of riding you do and to the  
treatment to which you submit the bicycle and its components. The warranty is not meant to suggest  
that the bicycle or a component cannot be broken or will last forever. It only means that the bicycle or  
component is covered subject to the terms of the warranty.  
BPSA-om9-5A  
The “useful life” of this component (the time during which the component is safe to ride) will be  
reduced if (1) you use it more than the average user; (2) you are heavier than the average rider; (3) the  
terrain/roads you ride on is rougher than average; (4) you tend to be harder on components than the  
average rider; (5) you fail to follow its installation instructions or maintenance instructions, including  
lubrication and adjustment; (6) it must endure more adverse environmental conditions than the  
average component (i.e. sweat, corrosive mud, salty beach air etc.); (7) you damage/weaken it in a  
crash, jump or through other abuse; (8) you fail to purchase the appropriate model of product for the  
type of riding it endures; and/or (9) you race with the component or participate in any other type of  
extreme, aggressive riding such as Aggro, Hucking, Freeride, North Shore, Downhill, Jumping, Stunt  
Riding, etc. The more factors you meet and the more often they occur, the more this component’s life  
will be reduced, however it is impossible to say how much.  
Racing (road, mountain or triathlons) places extreme stress on bicycles and their components (like  
it does riders) and significantly shortens their usable or “useful” life (the time during which the  
component is safe to ride). If you participate in these types of events, the lifetime of the product may  
be significantly shortened depending upon the level and amount of racing. The “normal wear” of a  
component may differ greatly between competitive and non-competitive uses, which is why  
professional level riders often use new bikes and components each season as well as having their  
bikes serviced by professional mechanics after each ride. Particular care should be placed in the  
regular examination of your bicycle and it’s components to insure your safety.  
UL2-0508-1  
If you engage in extreme, aggressive stunt or competition riding, you will get hurt, and you  
voluntarily assume a greatly increased risk of injury or death.  
Not all bicycles, components or equipment are designed for these types of riding, and those that  
are may not be suitable for all types of aggressive riding. Check with the bicycle’s or component’s  
manufacturer about suitability before engaging in extreme riding.  
When riding fast down hill, you can reach speeds achieved by motorcycles, and therefore face  
similar hazards and risks. Have your bicycle and equipment carefully inspected by a qualified  
mechanic and be sure it is in perfect condition. Consult with expert riders, area site personnel and race  
officials on conditions and equipment advisable at the site where you plan to ride. Wear appropriate  
safety gear, including an approved full face helmet, full finger gloves, and body armor. Ultimately, it is  
your responsibility to have proper equipment and to be familiar with course conditions.

Although many catalogs, advertisements and articles about bicycling depict riders engaged in  
extreme riding, this activity is extremely dangerous, increases your risk of injury or death, and  
increases the severity of any injury. Remember that the action depicted is being performed by  
professionals with many years of training and experience. Know your limits and always wear a helmet  
and other appropriate safety gear. Even with state-of-the-art protective safety gear, you could be  
seriously injured or killed when jumping, stunt riding, riding downhill at speed or in competition.  
BPSA-OM9-2F  
a. Maintenance  
WTB LaserDisc hubs use sealed bearings and protected mechanisms; but, like anything mechanical, they  
are subject to wear and corrosion from moisture, dirt and salt. The best maintenance for your WTB hubs is to  
clean them with water and a soft brush or lint-free cloth.  
Do not use water under high pressure to blast off dirt and mud. The water could penetrate the seals and  
damage the bearings and other metal parts.  
Periodically lubricate the threads and cam surfaces on the quick release skewer or the threads on the axle  
bolts of the Single Duty hub.  
Before each use, check brake wear and operation; spoke tension, rim wear, damage and trueness; and tire  
fit, wear, damage and inflation. Spin each wheel slowly and look for any signs of damage: dents, bulges,  
cracks, or deformation of the rims. Check spoke tension, by spinning the wheel to make  
sure it is true (no side-to-side wobble, no up-and-down hop); by squeezing pairs of  
spokes to make sure none are loose or broken; and by plucking each spoke to make sure  
they all sound about the same. If you discern a difference in tension when squeezing two  
adjoining spokes or in the pitch of the sound of a plucked spoke this may indicate a  
significant difference in that spoke’s tension. If in doubt about spoke tension or wheel  
trueness, do not ride the bike. Take it to a qualified bicycle mechanic.  
With rim brakes, check that the wear indicator on the sidewall braking surface is still  
clearly visible.  
Before every ride, check the tires for excess wear, cuts in the tread and cuts or  
bulges in the sidewall. Check the tire pressure of both tires. The tire’s pressure rating is marked on the  
sidewall.  
Spoke tensioning and wheel truing is a highly refined skill which requires expensive  
CAUTION:  
special tools and experience. Do not attempt to tension or true a wheel unless you have the  
knowledge, experience and tools needed to do the job correctly.  
WH2-0508-1  
WARNING: Do not ride a bike with a damaged tire or rim. Riding a damaged tire or rim may lead to  
sudden tire deflation or improper braking function. Sudden tire deflation or improper braking function  
can cause loss of control, resulting in serious injury or death. Replace damaged tires and rims before  
riding the bike.  
Never inflate a tire beyond the maximum pressure, or ride a tire with less than the minimum  
pressure marked on the tire’s sidewall. Exceeding the recommended maximum or minimum pressure  
may cause sudden tire failure. Tire failure can cause loss of control, resulting in serious injury or  
death.  
TI1-0508-1  
b. Service and Repair  
We strongly urge you to have any servicing or repair of your WTB components done by a qualified bicycle  
mechanic with the appropriate tools, knowledge and experience. If you believe that you are qualified to service,  
replace parts or repair a WTB component, please download, read and follow the Service Instructions at  
wtb.com/tech/serviceinstructions for the component which you plan to repair.
