Sag is the amount of shock travel that is used as the rider sits stationary on the bike. Typically,
sag is 15 to 25 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 all RockShox rear shocks, change the air spring rate to set sag.
Adjusting air pressure determines the spring rate, or stiffness, of the shock. The more air you
put in, the firmer your shock will be.

1. Ensure the shock is in the open position.
2. Depressurize the air chamber by removing the air cap and depressing the valve core stem.
3. Because every bike is different, a good starting point is to pressurize the air chamber to an air pressure
equaling half your body weight (psi to pounds).

4. After adding air to your shock based on your body weight, and without sitting on the bike, move travel
indicator o-ring up next to the air can.
5. Applying your full weight, gently sit on the bike and then dismount. Measure the distance from the o-
ring to wiper seal. Write it down. This measurement is your sag. Determine what percentage of total
shock stroke this sag represents.
Example – The shock installed on the bicycle measures 165mm with 38mm of stroke. Typical
suspension sag would be between 5.7 and 9.8mm.
RockShox rear shocks are commonly available in the following length (eye to eye) and stroke
combinations:
Ario and MC
Pearl
6. 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.

By turning the gold Floodgate adjuster on the MC shock, you can tune your desired level of
efficiency. Turning the adjuster clockwise increases the efficiency of your shock, reducing
pedal induced bob. You will note the difference when you are in the middle/Floodgate (MC 3.3
and Pearl 3.3) or 'Lock' (MC 3.R) settings.
Begin with the Floodgate adjuster in the full counterclockwise position. On flat, smooth
pavement, begin riding at your normal pedal cadence. Increase the Floodgate setting by turning
the adjuster clockwise until no movement is felt in the shock. Alternatively, use an assistant to
watch your riding, paying particular attention to suspension movement.
