Fork installation

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).
w a r n i n g
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.
3. 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. Do not use any
cantilever brake other than those intended by the brake manufacturer to work with a hangerless
brace.
4. 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.
5. Keep in mind tire clearance as you choose tires. Maximum size is .3" wide installed. Be sure to
check this diameter whenever you change tires. To do this, remove the top caps and spring stack
assemblies and compress the fork completely to make sure at least 5 mm of clearance exists
between the top of the inflated 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.
PoPloC reMote installation
The PopLoc Remote Lockout lever allows the rider to control the movement of their suspension fork
without removing their hands from the handlebars. Specific left and right PopLocs are available.
If needed, remove the grip, brake lever, and shifter from the handlebar. If you are unfamiliar with the
removal of these items, please consult the manufacturer's instructions.
1. Slide the Poploc onto the handlebar.
. Re-install the shifter, brake lever, and grip on the handlebars. If you are unfamiliar with the
installation of these items, please consult the manufacturer's instructions. Always adhere to the
recommended torque specifications for these items.
3. Position the PopLoc as desired on the handlebar and tighten the clamp bolt to 0 in-lb (.5 Nm)
4. Forks with PopLoc Adjust: Turn the blue compression adjustment dial counterclockwise until it stops.
5. Press the release button on the PopLoc.
6. Install the cable in the PopLoc.
7. Install the cable into the housing.

8. Feed the cable and housing into the cable stop on the fork crown.
9. Gently pull on the cable and align it with the groove in the rotating cam of the Motion Control
damper.
10. Tighten the cable fixing bolt on the rotating cam to 8 in-lb (.9 Nm)

PerForManCe tUning
RockShox forks can be tuned for your particular weight, riding style,
and terrain.
setting sag
Dart forks are designed to sag when you are sitting on your bike.
Sag is the compression of the fork caused by the rider's weight.
Proper sag allows the front wheel to follow the contour of the terrain
as you ride.
Sag is adjusted by turning the top cap preload adjuster (fig 1).
Turning the adjuster clockwise increases spring preload (i.e.
stiffening the spring) decreasing sag. Turning the adjuster counter
clockwise decreases spring preload which increases sag.
To measure sag, install a zip tie on the upper tube of the fork flush against the dust wiper. Sit on the bike
with normal riding apparel. Step off the bike, and measure the distance between the dust wiper and the
zip tie. This is your sag. Adjust the preload as needed to reach the recommended sag.

Coil sPring tUning
Changing the sPring rate
Spring rate is the amount of force needed to compress a spring one inch. Changing your fork's coil
spring for a spring of a higher or lower rate will alter the overall feel of your fork. Higher spring rates
make the fork feel more "stiff", while lower spring rates make the fork more "supple". Contact your local
RockShox dealer to order replacement springs.
reboUnd daMPing
external reboUnd adjUstMent (dart 2 with tUrnkey oPtion/dart 3)
Rebound damping controls the speed at which a fork returns to its full extension following compression.
Located at the bottom of the right fork leg is the rebound adjuster knob. Turning the adjuster in the
direction indicated by the "rabbit" on the rebound speed decal decreases rebound damping, causing
the fork to return to full extension faster. Turning the adjuster in the direction indicated by the "turtle"
increases rebound damping, slowing the return of the fork to full extension.
Excessive rebound damping will cause the fork to "pack up" over successive bumps, reducing travel
and causing the fork to bottom out. Set your fork to rebound as fast as possible without "topping out" or
kicking back. This allows your fork to follow the contours of the trail, maximizing stability, traction and
control.
