Before You Ride

Make sure that your fork is ready to ride

  1. Check that quick-release levers are properly adjusted and tightened.
  2. 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 for further inspection and repair.
  3. Check your headset adjustment. If loose, adjust it accordingly to your bicycle manufacturer's recommendations.
  4. Check that all brake cables or hoses are properly fastened.
  5. Test the proper operation of your front and rear brakes on level ground.
  6. Before every race or ride, clean the outside of your fork with only mild soap and water, and wipe dry with a soft dry rag. Do not spray water directly into the seal/upper tube junction. Do not use a high pressure washer on your fork.


Setting Fork Air Pressure

32 TC maximum air pressure is 150psi/ 10.3 bar

32 Step-Cast and Rhythm maximum air pressure is 140psi/ 9.6 bar

34 FLOAT, FLOAT SC, and 34 Rhythm maximum pressure is 120psi/ 8.3 bar

NOTE: Pressure measured at an ambient temperature of 70-75F. Normal operating temperature range for FOX products is 20-140F.

Sag should be set to 15 - 20% of total fork travel

To achieve the best performance from your FOX suspension, adjust the air pressure to attain your proper sag setting. Sag is the amount your suspension compresses under your weight and riding gear. Sag range should be set to 15–20% of total fork travel.

 

  1. Unscrew the air cap on top of the left fork leg counter-clockwise to expose the Schrader valve. 32-34-sag-range.jpg
  2. Attach a FOX High Pressure Pump to the Schrader valve.
  3. Pump your fork to the appropriate pressure as listed in the 'Suggested starting points for setting sag' table below, then remove the pump.
  4. Using your forks sag setting o-ring on the left upper tube (or temporarily install a zip tie to the upper tube), slide the o-ring (or zip tie) down against the fork dust wiper.
  5. Rotate the compression lever to the Open mode (fully counter-clockwise).
    • If you have a Remote fork, set the fork to Open mode.
  6. Dressed to ride (including a filled hydration pack, if you use one), position your bike next to a wall or table to support yourself. Mount your bicycle. Assume your riding position for at least 10 seconds, allowing the suspension to fully settle. Make sure you distribute your weight evenly between the saddle, handlebars and pedals.
  7. While in your riding position, slide the o-ring (or zip tie) down against the fork dust wiper.
  8. Dismount your bike without bouncing, to avoid further moving the o-ring or zip tie. Measure the distance between the dust wiper and the o-ring or zip tie. This is your sag measurement. Suggested sag measurements are listed in the table below.
  9. Add or remove air pressure until your sag measurement is between 15-20% of your forks total travel.
  10. Repeat steps 2-8 and recheck sag measurement.
  11. When sag measurement is correct, screw the air cap on clockwise until snug.

Adjusting Rebound

Rebound controls how fast the fork extends after compressing

The rebound adjustment is dependent on the air pressure setting. For example, higher air pressures require more rebound damping.

Use your air pressure to find your rebound setting. Turn your rebound knob to the closed position (full clockwise) until it stops. Then
back it out (counter-clockwise) to the number of clicks shown in the table below.

Adjust rebound until when tested, the fork returns quickly but does not top out.

Top out is felt when a fork fully extends too quickly and comes to an abrupt stop when it reaches full extension (you will hear/feel a small noise). Top out should be avoided through proper rebound setting.



Adjusting GRIP Compression Damping

The 3-Position Micro Adjust lever is useful to make on-the-fly adjustments to control fork performance. Use the positions between the OPEN, MEDIUM, and FIRM modes to fine-tune your compression damping.

 

2025-Grip.jpg



Adjusting GRIP SL Compression Damping

The 3-position lever is useful to make on-the-fly adjustments to control fork performance under significant changes in terrain, and is intended to be adjusted throughout the ride.
Use the OPEN mode during rough descending, the MEDIUM mode for undulating terrain, and the FIRM mode for smooth climbing.

 

2025-GRIP-SL.jpg



Adjusting Grip X Compression Damping

High-speed compression adjustment is useful to control fork performance during bigger hits, landings, and square-edged bumps.

Low-speed compression adjustment is useful to control fork performance during rider weight shifts, G-outs, and other slow inputs.

 

Turn your compression adjusters to the closed position (full clockwise) until they stop. Then back them out (counterclockwise) 10 clicks each  for High-speed and Low-speed compression.

Adjusting Grip X2 Compression Damping

High-speed compression adjustment is useful to control fork performance during bigger hits, landings, and square-edged bumps.

Low-speed compression adjustment is useful to control fork performance during rider weight shifts, G-outs, and other slow inputs.

 

Turn your compression adjusters to the closed position (full clockwise) until they stop. Then back them out (counterclockwise) 5 clicks for High-speed and 10 clicks for Low-speed compression.

Remote Installation

 

The remote can either be installed under the handlebar on the non-drive side, where a front shifter would typically be placed, or installed above the handlebar on the drive side. The remote can be used with two cables to control forks and shocks simultaneously. 

 

GRIP/GRIP SL/GRIP X DAMPERS (Push-to-Lock)

1. Install the remote lever onto your handlebar. Do not exceed 1.7 N•m (15 in-lb). Less torque may be needed for carbon bars. Refer to the handlebar manufacturer’s instructions for use with carbon bars. Make sure to check for clearance between the remote lever and any brake or shifter controls.


2. Route the cable housing from the fork topcap, around the rear of the crown, to the remote lever and cut to length. Install a ferrule on the end of the housing at the remote lever and at the fork topcap.


3. Install a short piece of housing with one ferrule between the in-line barrel adjuster and the remote lever body.


4. Push the larger remote lever to its actuated position, this is FIRM mode. Make sure that the cable head is completely seated in the remote lever.


5. Use a 5 mm hex wrench to turn the remote pulley clockwise to approximately 0.56 N•m (5 in-lb). While holding the 5 mm hex and pulley in this position, push on the fork to see if the blow off force is sufficient for your preference. Adjust the pulley clockwise for more FIRM mode force, counter-clockwise for less FIRM mode force until you find your desired setup. Note the position of the pulley set screw for your desired setup.


6. With all cable housing fully seated and no slack in the system, lightly lubricate the inner cable and thread it through the cable housing and around the fork remote pulley. With the 5 mm hex wrench still holding the remote pulley in the position for your desired FIRM mode force (from Step 5), tighten the pinch bolt to 1.13 N•m (10 in-lb).


7. Release the 5 mm hex wrench from the remote pulley. Test the remote actuation to make sure it is functioning properly. Then cut off the excess inner cable and crimp the end.


8. The in-line barrel adjuster may be used to change the lockout blow-off force. Clockwise barrel adjustment increases blow-off force, while counter-clockwise adjustment decreases blow-off force.

 

 

GRIP/GRIP SL/GRIP X DAMPERS (Push-to-Unlock)

1. Install the remote lever onto your handlebar. Do not exceed 1.7 N•m (15 in-lb). Less torque may be needed for carbon bars. Refer to the handlebar manufacturer’s instructions for use with carbon bars. Make sure to check for clearance between the remote lever and any brake or shifter controls.


2. Route the cable housing from the fork topcap, around the rear of the crown, to the remote lever and cut to length. Install a ferrule on the end of the housing at the remote lever and at the fork topcap.


3. Install a short piece of housing with one ferrule between the in-line barrel adjuster and the remote lever body.


4. Leave the actuation lever in its un-actuated position, this is FIRM mode. Make sure that the cable head is completely seated in the remote lever.


5. Note that the Push-to-Unlock damper is in FIRM mode by default. Push on the fork to see if the FIRM mode blow off force is sufficient for your preference. If so move to Step 6. If not, use a 5 mm hex on the pulley to adjust the pulley slightly (clockwise for more FIRM mode force, counter-clockwise for less FIRM mode force) to find your desired setup.


6. With all cable housing fully seated and no slack in the system, lightly lubricate the inner cable and thread it through the cable housing and around the fork remote pulley. If needed (from Step 5), with the 5 mm hex wrench still holding the remote pulley in the position for your desired FIRM mode force, tighten the pinch bolt to 1.13 N•m (10 in-lb).


7. Release the 5 mm hex wrench from the remote pulley. Test remote actuation to make sure it is functioning properly. Cut off the excess inner cable and crimp the end.


8. The in-line barrel adjuster may be used to change the lockout blow-off force. Clockwise barrel adjustment decreases blow-off force, while counter-clockwise adjustment increases blow-off force.



Using the 2-Position Remote

The 2-position remote is designed to be used in place of a front shifter, under the handlebar on the rider's left side. The 2-position remote can be used with 2 cables to control both the front fork and rear shock simultaneously.

 

2-pos-remote.jpg

 

The 2-Position Remote lets you to switch between the OPEN and FIRM modes while riding.

  • Push-to-Lock – Push the actuation lever to set the fork to FIRM mode. Push the release lever to set the fork to OPEN mode.
  • Push-to-Unlock – Push the actuation lever to set the fork to OPEN mode. Push the release lever to set the fork to FIRM mode.

                                               



Tuning with Air Volume Spacers

Changing volume spacers is an easy internal adjustment that allows you to change the amount of mid stroke and bottom out resistance.

  • If you have set your sag correctly and are using full travel (bottoming out) too easily, then you could install one or more spacers to increase bottom out resistance.

  • If you have set your sag correctly and are not using full travel, then you could remove one or more spacers to decrease bottom out resistance.
