4.
To prevent damage to the carbon crown-steerer, a qualified technician should take care when installing
or removing the crown race.
5.
Remove any burrs from the stem clamp edges before installation on the carbon crown-steerer. Do not
use a hammer to install your stem.
6.
Follow the stem manufacturer's torque specifications when installing a stem. Exceeding the torque
specifications may damage the carbon crown-steerer and reduce the strength of the fork. Cotter style
stems are not recommended as the small surface area may cause damage, especially when overtorqued.
7.
Do not let brake or derailleur cables rest on, or be attached to the crown. Abrasion over time may cause
damage to the crown. If contact is unavoidable, use tape or similar protection to cover the surface.

RockShox SID forks can be tuned for your particular weight, riding style, and terrain.
S e t t i n g S a g
SID 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 increasing or decreasing the positive air pressure of
your fork. Increasing the pressure in your positive chambers will decrease sag. Decreasing the
pressure in your positive air chambers will increase sag.
To measure sag, use the travel indicator on the upper tube of the fork and ensure it is flush
against the wiper seal. Sit on the bike with normal riding apparel. Step off the bike, and
measure the distance between the wiper seal and the travel indicator. This is your sag. The sag
should be approximately 20 percent of maximum travel.
A i r P re s s u re G u i d e l i n e s
The positive air chamber is the fork's spring. Always tune positive air pressure first, based on
the desired sag. More positive air gives a firmer ride, while less positive air gives a
softer/plusher ride. Use the tables below to assist with positive and negative air pressure.

Remove the air cap to expose the air valve (on the left fork leg). Using a RockShox Air Pump
(with schrader valve), add the recommended air pressure (see "Air Pressure Guidelines").

Adjusting your forks negative air pressure will change its ride characteristic. More negative air
pressure will make the fork more active over small bumps. Less negative air pressure will
reduce bobbing. Set the negative air between 50 and 90 percent of the positive air pressure
depending on terrain and riding style. Always tune positive air pressure first, then adjust
negative air pressure.

Remove the schrader air cap from the bottom of the left shaft air valve. Using a RockShox air
pump, add the recommended air pressure through the bottom of the left shaft air valve. A small
amount of lubricant can escape while adjusting the negative air, use care to avoid contamination
of the disc brake rotors.

CAUSE THE FORK TO LOSE TRAVEL

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.
C h a n g i n g Tra ve l
To measure the amount of travel your fork has, measure the amount of exposed upper tube.
To change the travel of your fork for 80 to 63 mm you must perform a full service on your fork.
To obtain service information or instructions, visit our website at www.rockshox.com or contact
your local RockShox dealer or distributor.
Your fork uses the Motion Control Damping System. This system provides maximum ride
control, allowing the rider to smooth out the bumps, with on-the-fly adjustable compression
damping (including lockout for climbing).
Installation of PopLoc Remote on the SID Motion Control Damper
Before starting, clean and inspect the fork. You should perform any needed service (i.e.,
bleeding or rebuilding the Motion Control damper) before installing the PopLoc Remote. For
full technical documentation visit www.rockshox.com.
