Congratulations!
You have the best in suspension components on your bicycle! This manual contains important
information about the safe operation and maintenance of your shock. To insure that your RockShox shock 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 bicycling experience more enjoyable and trouble-free.

It is extremely important that your RockShox SID rear shock is installed correctly by a qualified bicycle mechanic with proper
tools. Consult your bicycle manufacturer’s instructions for proper installation of your SID shock.

By adjusting the air pressure, the SID rear shock can be tuned for your particular weight, riding style, and terrain. You may
benefit by making tuning adjustments to suit your specific needs. When tuning suspension, always make one change at a time
and write it down. This allows you to understand how each change affects your ride.

Sag is the amount of shock travel that is used as the rider sits stationary on the bike. Typically, sag is 15 to 30 percent of all
available wheel travel. Check with your bicycle manufacturer to determine the rear wheel travel and recommended sag for your
particular bike before setting sag. For the SID rear shock you will be changing the air spring rate to set sag.
Adjusting main chamber air pressure determines the spring rate, or stiffness, of the shock. The more air you put in, the firmer
your shock will be. Maintain air pressure between 100 and 250 psi.
S e l e c t i n g A i r P re s s u re ( S p r i n g R a t e ) :
1. Depressurize the main and opposing air chamber by removing the air cap and depressing the valve core stems.
2. Because every bike is different, a good starting point is to pressurize the main air chamber to an air pressure equaling your body weight.

3. Without sitting on the bike, measure the distance from the floor to the seat (rear height). Write it down.
4. While you sit in a normal riding position, have a friend measure the same distance. The difference between the two measurements is sag. Determine what percentage
of total wheel travel this sag represents.
5. If the sag is less than your bicycle manufacturer’s recommendation, a lower air pressure should be used. If the sag is greater than your bike manufacturer’s
recommendation, a greater air pressure should be used.

RIDING A BIKE IS DANGEROUS. NOT PROPERLY MAINTAINING OR INSPECTING YOUR BIKE IS EVEN MORE
DANGEROUS. IT’S ALSO DANGEROUS NOT TO READ THESE INSTRUCTIONS.
1. Before riding the bicycle, be sure the brakes are properly installed and adjusted. If the brakes don’t work properly, the
rider could suffer serious and/or fatal injuries.
2. If the shock ever loses oil or if it makes sounds of excessive topping out, stop riding the bicycle immediately and have
the shock inspected by a dealer or call RockShox. Continuing to ride with the shock in either of these conditions could
result in loss of control of the bicycle with possible serious and/or fatal injuries.
3. Always use genuine RockShox parts. Use of after-market 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.
