I NSTALLATION
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.
1. 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).
2. 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.
3. Install the brakes according to the manufacturer's instructions and adjust brake pads properly. Use the fork only with
V-type or hydraulic cantilever brakes mounted to the existing brake posts or disc style brakes mounted through the
provided mounting holes. Do not use any cantilever brake other than those intended by the brake manufacturer to
work with a hangerless brace.
4. 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.
5. Keep in mind tire clearance as you choose tires. Maximum tire size is 26 x 2.1" wide or 664 mm diameter installed. Be
sure to check this diameter whenever you change tires. To do this, remove the air pressure from the fork 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.
CARBON CROWN-STEERER INSTALLATION (WORLD CUP ONLY)
The SID World Cup is designed for cross-country riding and racing. The one piece carbon
crown-steerer accounts for the unique loads and stresses of mountain bike riding, while
providing vibration damping and ride control unmatched by traditional material technologies.
This fork is not designed for extreme applications, such as downhill style riding or
jumping. We recommend using one of our other forks such as Boxxer or Psylo for this
type of riding.
For installation, follow the instructions below as well as the instructions in your owner's
manual.
Installation for Carbon Crown-Steerer
It is extremely important that your fork is installed correctly by a qualified bicycle mechanic.
Improperly installed forks are extremely dangerous and can result in severe and/or fatal
injuries.
1. Use a 28-tooth blade to cut the carbon steerer. For safe handling, smooth the cut surface area with 400 grit sand
paper. Apply masking or duct tape to the outside of the steerer tube to help prevent carbon fraying during cutting.
2. Do not use star nuts. Use only expansion style plugs such as the one supplied with the fork. Do not exceed 100 in-lb
of torque. Torque values may vary depending on headset design and condition.
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.
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. If the brakes do not work 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 fork’s drop-outs. Not securing the rear
can allow the bike’s 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. Only 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.
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 COMMISSION’S (CPSC)
REQUIREMENTS FOR BICYCLE STANDARDS IF THE FORK IS GOING TO
BE USED ON PUBLIC ROADS AT ANY TIME.
