the crown. The upper tubes, on clamp type crowns, must not extend above the crown more than 1mm.
8. Hangerless Reflector Bracket Installation: Orient black reflector bracket to the front of the
fork with the 90 degree bend under the fork brace. Place the .040" thick flat washers onto the hex bolt
and insert this assembly through the lowest oval hole in the bracket and through hole in brace. Place
star washer and thread nut onto bolt at back of brace. Torque to 60 in-lb. (6.8Nm).
Hangered Reflector Bracket Installation: Orient the black reflector bracket with the hook
of the bracket facing up and to the fork brace. Place the star washer onto the hex bolt and insert the
bolt and star washer through the rear hole on the hook of the bracket. Thread the bolt through the hole
on fork brace. Torque to 20in-lb. (2.3Nm).
SID XL Installation Instructions
1. Remove the existing fork and lower headset race from the bicycle.
2. Before you install a XL on the bicycle,
verify that the fork has been supplied
with the correct upper crown. Refer to
Fig. 2 for upper crowns available for XL
and to maximize fork stiffness by
proper selection and orientation of the
upper crown.
3. The steerer tube may need cutting to
proper length. To cut the steerer tube,
removal of the upper tubes are required.
This is necessary otherwise the upper
tubes will be in the way when cutting
the steerer tube to proper length. The
steerer tube length is determined by the
following parts: XL upper crown steerer
clamp length, stem steerer tube clamp
length, frame head tube length and top
and bottom headset stack height (see
Fig. 3). To ease in the assembly, do not
install the XL upper crown on to the
upper tubes until the steerer has been
cut to the proper length and the lower
crown has been fastened in the required
position. HINT: MEASURE TWICE AND
CUT ONCE!

4. Install the headset race firmly against the top of the fork crown once the steerer tube has been cut to
proper length.
5. Install the upper tubes into the lower crown and locate the lower crown so that 170mm of upper tubes
extends above the lower crown. Torque the lower crown bolts to 60in-lb.

6. Assemble the headset, upper crown and stem on the bicycle. Adjust the headset so you feel no play or
drag. Complete the installation of the headset and stem according to the manufacturer's instructions.
Torque all the upper crown bolts to 90in-lb.
7. Complete the rest of the XL installation by following steps three through seven under "Installation
Instructions (SID XC and SL)," page 7.
Tuning Your Fork
RockShox SID can be tuned to your particular weight, riding style and terrain. Our forks are set up for the 140
to 180lb (64 to 80kg) cross country racer. SID can be tuned to your specific needs by changing air pressure in
either or both the negative air chamber and main air chamber or through the C3 dual adjust cartridge.
When tuning suspension, always make one change at a time and write it down. Keeping a record lets you know
what changes you have tried and suggest what changes you might try. Ask a shop or local riders what they
have found works well. These resources are typically your best bet, but don't hesitate to call RockShox about
specific tuning needs. A list of phone numbers is on page 21 or check our web-site at www.rockshox.com.
S
ELECTING
The air pressure you run in both the main and negative air chambers (air springs) varies depending on weight
and riding style. The optimum setting for sag is between 3 and 8mm of total fork travel. Changing the main
or negative air spring pressure alters the sag and firmness of the fork. Suggested air pressure settings based
on rider weight and style are as follows:
• R /A R S
ACING GGRESSIVE IDE TYLE
a. Little or no sag for reduced bob from climbing.
b. Negative spring pressure equal or less than the main spring pressure setting.
• P /F R S
LUSH REE IDE TYLE
a. 3 to 5mm of sag for supple and active ride.
b. Negative air spring pressure set to twice the main air spring pressure setting.
Note: using more than twice the main air spring pressure may result in reduced total fork travel.
Refer to the chart on page 10 for general riding style guidelines for setting the main and negative air pressure
in your fork.
