Installing Your Fork

Be sure your fork is properly installed before proceeding. If your fork came pre-installed on your bicycle, continue to the next section.

Before You Ride

1. Check that your 20 mm axle pinch bolts and crown pinch bolts are properly adjusted and tightened.
2. Clean the outside of your fork with only mild soap and water, and wipe dry with a soft dry rag.

   NOTE:  Do not use any solvents or de-greasers, as these products can cause serious damage to paint and anodized parts (upper tubes, knobs, steerers).

   Do not spray water directly on the seal/upper tube junction. Do not use a high pressure washer on your fork.

3. Inspect the entire exterior of your fork. The fork should not be used if any of the exterior parts appear to be damaged. Contact your local dealer or FOX Racing Shox for further inspection and repair.
4. Check your headset adjustment. If loose, adjust it accordingly to your bicycle manufacturer's recommendations.
5. Check that all brake cables or hoses are properly fastened.
6. Test the proper operation of your front and rear brakes on level ground.

Setting Sag

To get the best performance from your fork, it is necessary to set the proper air spring pressure by adjusting sag. Generally, sag should be set to 15 – 25% of total fork travel.

1. Unscrew the blue aircap on top of the left fork leg to expose the Schrader valve.
   
2. Attach a FOX Racing Shox High Pressure Pump to the Schrader valve.
3. Pump your fork to the appropriate setting from the Suggested Air Spring Pressure Settings table below, then remove the pump.
4. Unless your fork already has a sag setting o-ring on an upper tube, install a zip tie to an upper tube. Slide the o-ring or the zip tie down against the scraper lip of the fork dust seal.
5. Make sure the low-speed compression is open (fully counter-clockwise out).
6. Dressed to ride, position your bike next to a wall or table to support yourself. Without bouncing, mount your bicycle. Assume a normal riding position for at least 30 seconds, allowing the suspension to fully settle.
7. Dismount your bike without bouncing downward, without further moving the o-ring or zip tie. Measure the distance between the seal and the zip tie. This measurement is your sag value.
8. Compare your actual sag value to your target sag value in the Sag Setup table below.
   
   If your sag measurement value is less than the Sag Setup table value, screw on the pump fitting, note the current air pressure setting and depress the black bleed-valve to reduce the gauge pressure by 5 psi. Measure sag again and repeat this adjustment, if necessary.
   
   If your sag measurement value is greater than the Sag Setup table value, screw on the pump fitting, note the current air pressure setting and pump to increase the gauge pressure by 5 psi. Measure sag again and repeat this adjustment if necessary.
9. Screw the blue aircap back on.
10. Check your rebound adjustment; adjust it if necessary.

    Sag Troubleshooting
    Symptom	Remedy
    Too much sag	(+) air pressure in 5 psi increments
    Too little sag	(-) air pressure in 5 psi increments
    Excessive bottoming	(+) air pressure in 5 psi increments
    Harsh ride; full travel not utilized	(-) air pressure in 5 psi increments

Adjusting Rebound

The rebound adjuster knob is located at the bottom of the right fork leg, as shown in the above figure.

Rebound controls the rate of speed at which the fork extends after compressing. Turning the knob clockwise slows down rebound; turning the knob counter-clockwise speeds up rebound. As a starting point, turn the rebound adjuster knob all the way clockwise (full in) until it stops, then turn counter-clockwise (out) 12 clicks.

Adjusting Low-Speed Compression

Low-speed compression damping controls the influence of your forward and reverse weight shifts, and how your bike feels and performs when braking. This adjuster rotates to stops at each end and has 24 clicks of adjustment. It is factory-set at 12 clicks out from the fully closed (clockwise) position.

Adjusting High-Speed Compression

High-speed compression damping controls the force it takes to move the fork through its travel, or how quickly the wheel responds to a bump. This adjuster rotates to stops at each end and has 24 clicks of adjustment. It is factory-set at 12 clicks out from the fully closed (clockwise) position.
