Congratulations! You have the best in suspension components on your bicycle! This

manual contains important information about the safe operation and maintenance of your

fork. To ensure that your RockShox fork performs properly, we recommend that you have

your fork installed by a qualified bicycle mechanic. We also urge you to follow our

recommendations to help make your riding experience more enjoyable and trouble-free.

It is extremely important that your RockShox fork is installed correctly by a qualified

bicycle mechanic. Improperly installed forks are extremely dangerous and can result

in severe and/or fatal injuries.

Remove the existing fork from the bicycle and the crown race from the fork. Measure the length of the

fork steerer tube against the length of the RockShox steerer tube. The RockShox steerer tube may need

cutting to the proper length. Make sure there is sufficient length to clamp the stem (refer to the stem

manufacturer's instructions).

IMPORTANT

Consumer Safety Information

WARNING

1. The fork on your bicycle is designed for use by a single rider, on mountain trails,

and similar off-road conditions.

2. Before riding the bicycle, be sure the brakes are properly installed and adjusted. Use

your brakes carefully and learn your brakes’ characteristics by practicing your braking

technique in non-emergency circumstances. Hard braking or improper use of the front

brake can cause you to fall. If the brakes are out of adjustment, improperly installed or

are not used properly, the rider could suffer serious and/or fatal injuries.

3. Your fork may fail in certain circumstances, including, but not limited to, any

condition that causes a loss of oil; collision or other activity bending or breaking

the fork’s components or parts; and extended periods of non-use. Fork failure

may not be visible. Do not ride the bicycle if you notice bent or broken fork parts,

loss of oil, sounds of excessive topping out, or other indications of a possible fork

failure, such as loss of shock absorbing properties. Instead, take your bike to a

qualified dealer for inspection and repair. In the event of a fork failure, damage to

the bicycle or personal injury may result.

4. Always use genuine RockShox parts. Use of aftermarket replacement parts voids

the warranty and could cause structural failure to the shock. Structural failure could

result in loss of control of the bicycle with possible serious and/or fatal injuries.

5.Use extreme caution not to tilt the bicycle to either side when mounting the bicycle

to a carrier by the fork drop-outs (front wheel removed). The fork legs may suffer

structural damage if the bicycle is tilted while the drop-outs are in the carrier.

Make sure the fork is securely fastened down with a quick release. Make sure the

rear wheel is fastened down when using ANY bike carrier that secures the forks

drop-outs. Not securing the rear can allow the bikes mass to side-load the drop-

outs, causing them to break or crack. If the bicycle tilts or falls out of its carrier, do

not ride the bicycle until the fork is properly examined for possible damage.

Return the fork to your dealer for inspection or call RockShox if there is any

question of possible damage (See the International Distributor List). A fork leg or

drop-out failure could result in loss of control of the bicycle with possible serious

and/or fatal injuries.

6. Forks designed for use with ’v’-style brakes: o nly mount cantilever-type brakes

to the existing brake posts. Forks with hangerless style braces are only designed

for V- style or hydraulic cantilever brakes. Do not use any cantilever brake other

than those intended by the brake manufacturer to work with a hangerless brace.

Do not route the front brake cable and/or cable housing through the stem or any

other mounts or cable stops. Do not use a front brake cable leverage device

mounted to the brace. Forks designed for use with disc-style brakes: follow the

brake manufacturer’s installation instruction for proper installation and mounting of

the brake caliper.

7. Observe all owner’s manual instructions for care and service of this product.

ROCKSHOX FORKS ARE DESIGNED FOR COMPETITIVE OFF-ROAD RIDING AND

DO NOT COME WITH THE PROPER REFLECTORS FOR ON-ROAD USE. YOUR

DEALER SHOULD INSTALL PROPER REFLECTORS TO MEET THE CONSUMER

PRODUCT SAFETY COMMISSIONS (CPSC) REQUIREMENTS FOR BICYCLE

STANDARDS IF THE FORK IS GOING TO BE USED ON PUBLIC ROADS AT ANY TIME.

DO NOT ADD THREADS TO ROCKSHOX THREADLESS STEERERS. THE

STEERER TUBE CROWN ASSEMBLY IS A ONE-TIME PRESS FIT.

REPLACEMENT OF THE ASSEMBLY MUST BE DONE TO CHANGE THE

LENGTH, DIAMETER OR HEADSET TYPE (THREADED OR

THREADLESS).

DO NOT REMOVE OR REPLACE THE STEERER TUBE. THIS COULD

RESULT IN THE LOSS OF CONTROL OF THE BICYCLE WITH POSSIBLE

SERIOUS AND/OR FATAL INJURIES.

Install the headset crown race (29.9mm for 1 1/8" steerers) firmly against the top of the fork crown.

Install the fork assembly on the bike.

Adjust the headset until you feel no play or drag.

Install the brakes according to the manufacturer's instructions and adjust brake pads properly. Use the

fork only with disc style brakes mounted through the provided mounting holes.

Forks designed for standard quick releases: adjust the front wheel quick release to clear the

dropout's counter bore. The quick release nut must be tightened after the wheel is properly seated into

the dropout's counter bore. Make sure four or more threads are engaged in the quick release nut when

it is closed. Orient the quick release lever in front of and parallel to the lower tube in the locked

position. Forks designed for a thru-axle (not available for all forks) : follow the installation

instructions that follow for the Maxle Quick Release system

Keep in mind tire clearance as you choose tires. Maximum size is 2.4" wide or 696 mm diameter

installed . Be sure to check this diameter whenever you change tires. To do this, remove air pressure and

compress the fork completely to make sure at least 5 mm of clearance exists between the top of the tire

and the bottom of the crown. Exceeding maximum tire size will cause the tire to jam against the crown

when the fork is fully compressed.

The Motion Control Damping system allows riders to quickly adjust the feel and

performance of their suspension to match riding conditions without requiring pumps or

tools. This system provides for wide-ranging control of compression and rebound

damping as well as ‘Lock’ threshold sensitivity.

Proper setup of the Motion Control Damping system provides a range of options for efficient yet

comfortable performance. The instructions below describe setup and operation for both crown

and remote activated forks.

Gently pull on the cable and align it with the groove in the rotating cam of the Motion Control damper.

RockShox forks can be tuned for your particular weight, riding style and terrain.

Air Spring Tuning

With independently adjustable positive (top) and negative (bottom) air chambers, the air

spring system of your Reba fork can be easily tuned for your weight and riding style.

Use the following instructions as a starting point. If further fine tuning is desired,

follow the hints at the end of this section.

S TEP 1 - S ELECTING P OSITIVE A IR P RESSURE

Positive air pressure determines the amount of force required to compress your fork.

More positive air pressure will result in less suspension sag and higher bottom out

forces. Less positive air pressure will result in more suspension sag and lower bottom

out forces.

Using the chart below as a guideline, inflate the positive air chamber to the desired

pressure,

N OTE : A IR U-T URN PRESSURE SHOULD BE SET AT 115 MM OF TRAVEL .

‘O PEN ’ C OMPRESSION (F IG . 1)

In the ‘Open’ position, the Motion Control Damping system allows for maximum

compliance and fork movement. The ‘Open’ position provides ultimate control and

comfort on even the roughest terrain.

To return your fork to the ‘Open’ position:

•

For forks with the crown-mounted blue compression adjuster, rotate the adjuster fully

counterclockwise.

•

For PopLoc equipped forks, press the ‘Unlock’ release button on the remote (as indicated

by the open padlock icon on the button).

Negative air pressure effects the amount of force required to initiate suspension travel.

Negative air pressure works with bump input AGAINST the force of the positive air

chamber. More negative air pressure results in a suspension set-up that is more active,

especially to small bump input. Less negative air pressure results in a suspension set-

up does not move or "bob" under rider input or small bumps. Using the chart below as

a guideline, inflate the negative air chamber to the desired pressure.

‘L OCK ’ C OMPRESSION (F IG . 2)

In the ‘Lock’ position, the Motion Control system allows for a small amount of

controlled fork movement. This movement enables the front tire to track the terrain

without deflecting off obstacles, allowing for better traction and steering control when

compared to a complete lockout system. To activate the ‘Lock’, turn the crown-

mounted blue compression adjuster full clockwise or press forward on the PopLoc

Remote lever located on the handlebar.

Under ‘Lock’, heavier riders may find better performance with maximum Floodgate

settings, while lighter riders may find minimum Floodgate settings work best.

Experiment with higher or lower Floodgate settings while on the trail to optimize your

fork for your riding style and performance preferences.

Use the charts below to establish an initial Floodgate setting.

F LOODGATE A DJUSTMENT (F IG . 3)

All forks with Motion Control Damping allow for fine-tuning of the ‘Lock’ setting. The

rider can choose the point at which the ‘Lock’ setting can 'blow-off' and become active

to force inputs such as bumps or rocks. This adjustment is made using the Floodgate.

Depending upon fork model, the Floodgate is adjusted either internally (requires a

2.5mm hex wrench) or externally with the gold ‘Gate’ adjuster.

For crown mounted adjusters, hold the adjuster in the ‘Lock’ position while adjusting

the internal Floodgate.

ONLY . W HEN PERFORMING F LOODGATE ADJUSTMENTS , ENSURE THAT THE M OTION C ONTROL SYSTEM IS

ADJUSTED TO ‘L OCK .’

Under ‘Lock’, the maximum Floodgate setting results in a fork with minimal movement

while the minimum Floodgate setting results in increased fork movement.

N OTE : F OR MAXIMUM FORK SENSITIVITY AND MOVEMENT , RETURN THE FORK TO THE ‘O PEN ’ POSITION .

Floodgate settings should be used to adjust suspension compliance to medium sized

bumps and resistance to rider induced suspension movement (referred to as “bob”) in

the ‘Lock’ mode. When properly tuned, the Motion Control System will resist "bob," but

provide controlled suspension action in rough or aggressive terrain.
