NOTE: These air charts are designed as a recommended starting point only.
Please refer to your shock and fork owner’s manuals for additonal setup information.


1. Set sag:

• See the attached air chart for starting pressure. Use a high-pressure shock pump to add air.
• Push the rubber o-ring up to the seal, sit on the bike gently, dismount gently and measure the distance between the shock seal and the
o-ring (sag).
• Adjust air pressure until desired sag is reached. (This can be verified following the steps on p.6 or the measurements below the air chart).

Air pressures may vary depending on rider style and/or terrain.

2. Adjust rebound:

The red knob controls the rebound damping, the rate which the shock returns after the shock has been compressed.

• Turn the knob clockwise for slower rebound (slower speeds, bigger hits).
• Turn the knob counter-clockwise for faster rebound (higher speeds, small bumps, more traction.

Recommended sag:
-0% (4-7mm)

3. Adjust compression:

Specialized AFR shocks are equipped with a spike valve to optimize the shock’s compression.

Low-speed compression (induced by rider’s body weight - pitching, diving) is adjustable by turning the
blue knob.

• Turn the knob clockwise for a firmer, more efficient ride.
• Turn the knob counter-clockwise for a more supple ride, more traction.

NOTE: The spike valve system is a pre-set high-speed compression oil flow device configured to release a
large volume of oil to prevent shock spiking at higher frequencies (terrain induced impacts).
The adjustable low-speed compression knob bypasses the spike valve.

Setting the air pressure is crucial to getting the best performance from your rear shock and fork. Fork sag is
less of a factor for ride quality than it is for a rear shock, but it serves as a good starting point. The air charts
are designed to get you in the approximate sag range.
