Installing Your Shock

If you are installing your shock on a bike for which the shock is not original equipment:

  1. Install the shock.
  2. Remove the main air chamber air cap and let all the air out of the main air chamber.
  3. Carefully cycle the suspension through its entire travel.
  4. Check that all parts of the shock are clear of the frame and swingarm as it cycles through the travel.
  5. Pressurize your main air chamber to a minimum of 50 psi and no more than 300 psi. You will tune to a more specific air pressure in the Setting Sag section below.
  6. Set sag.

General Maintenance

There may be a small amount of air sleeve lubricant residue on the body. This is normal. If this residual air sleeve lubricant is not present, this is an indication that the air sleeve should be re-lubricated. Some other things to consider for all shock models:

  • If you ride in extreme conditions, service your shock and air sleeve more frequently. Check the maintenance schedule for your shock.
  • Wash your shock with soap and water only.
  • Do not use a high pressure washer to clean your shock.
  • Internal service should be performed by FOX Racing Shox or an Authorized Service Center.

Before You Ride

  1. Clean the outside of your shock 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 damage the shock's exterior finish or its anodized parts.

    Do not spray water directly on the seal/shock body junction. Do not use a high pressure washer on your shock.

  2. Inspect the entire exterior of your shock. The shock 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 or repair.
  3. Make sure that your quick-release levers (or thru-axle pinch bolts) are properly adjusted and tightened.
  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 set sag:

  1. Measure and set sag, and compare your result to the sag setting shown in the Air Spring Setting Guidelines table below.

    Air Spring Setting Guidelines

    Shock Travel
    (in./mm)

    25 % Sag
    (in./mm)

    1.00/25.4

    0.25/6.4

    1.25/31.7

    0.31/7.9

    1.50/38.1

    0.38/9.5

    1.75/44.4

    0.44/11.1

    2.00/50.8

    0.50/12.7

    2.25/57.1

    0.56/14.2

  2. If your measured sag value doesn't match the table value, add or release air pressure in 5 PSI increments:
    • if your measured sag value is less than the table sag 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. If necessary, measure and set sagagain and repeat this adjustment.
    • if your measured sag value is greater than the table sag value, screw on the pump fitting, note the current air pressure setting and pump to increase the gauge pressure by 5 psi. If necessary, measure and set sagagain and repeat this adjustment.
  3. Repeat until your target sag is achieved, then replace the air valve cap.

Adjusting Rebound

Rebound controls the rate at which your shock returns after it has been compressed. The proper rebound setting is a personal preference, and changes with rider weight, riding style and conditions. A rule of thumb is that rebound should be as fast as possible without kicking back and pushing the rider off the saddle.

The rebound knob has 8-10 clicks of adjustment.

For slower rebound, turn the red adjuster knob clockwise.

For faster rebound, turn the red adjuster knob counter-clockwise.

Adjusting Compression

The FLOAT RL has two suspension compression settings:

1. LOCKED (CLIMBING & ROAD RIDING)

2. OPEN (BUMP ABSORPTION)

Use these two settings to adapt the shock to your riding situation. For example, use the LOCKED position for riding to the top of the climb, and then switch to the OPEN position for the bumpy descent.

To determine which compression adjust position is best, pedal the bicycle at about 15 MPH and monitor the shock movement. Switch between positions and select the one that reduces suspension movement most effectively while providing the desired amount of bump absorption. The setting may change depending on conditions and riding styles.

Be sure your fork is properly installed before proceeding. Clicking on the link above will take you to a new page.

Before You Ride

  1. Check that quick-release levers are properly adjusted and tightened.

  2. Clean the outside of your fork with soap and water and wipe dry with a soft dry rag. Do not spray water directly on the seal/upper tube junction. Do not use a high pressure washer on your fork.

  3. Inspect entire exterior of fork for damage. The fork should not be used if any of the exterior parts appear to be damaged. Please contact your local dealer or FOX Racing Shox for further inspection and repair.

  4. Check headset adjustment. If loose, adjust according to manufacturer’s recommendations.

  5. Check that brake cables or hoses are properly fastened.

  6. Check that the front and rear brakes operate properly on flat land.

Setting Sag

You can also view a Flash video on Setting Sag.

To get the best performance from your fork, it is necessary to set and adjust sag. Generally, sag should be set to 15 – 25% of total fork travel.

  1. Unscrew the blue aircap (shown below) on top of the left fork leg to expose the Schrader valve.

  1. Attach a FOX Racing Shox High Pressure Pump to the Schrader valve.

  2. Using the Air Spring Settings table below, pump your fork to the appropriate setting = 4 && typeof(BSPSPopupOnMouseOver) 'function') BSPSPopupOnMouseOver(event);'>using the FOX High Pressure Pump, then remove the pump.

  3. Install a zip tie with light friction on the upper tube and push it down until it contacts the fork seal.

  4. Carefully sit on the bike and assume a normal riding position. The fork should compress slightly.

  5. Being careful not to further compress the fork, dismount the bicycle. Measure the distance between the seal and the zip tie. This distance is sag.

  6. Compare your sag measurement to the Sag Setup table below.
    If your sag is lower than on the table
    , 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 adjustment, if necessary.
    If your sag is higher than on the table
    , 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 adjustment if necessary.

  7. Screw the blue aircap back on, and go ride.

Adjusting Rebound

The rebound knob (shown below) is located on the top of the right fork leg, and has 12 clicks of adjustment. Rebound controls the speed at which the fork extends after compressing. Turning the knob clockwise slows down rebound; turning the knob counterclockwise speeds up rebound. As a starting point, turn the rebound adjuster knob all the way clockwise (full in) until it stops, then turn counterclockwise (out) 6 clicks.

Slow Rebound

Too slow and your fork will pack down and ride harsh.

If you increase your spring rate or air pressure, you will need to slow down your rebound

Fast Rebound

Too fast and you will experience poor traction and wheel hop.

If you decrease your spring rate or air pressure, you will need to speed up your rebound setting.

Locking Out the Fork

The blue compression lockout lever is located below the red rebound adjuster knob. It allows the rider to close the compression damping circuit in the fork. This keeps the fork at the top of its travel, making it harder to compress.

Rotate the lever fully clockwise to lockout the fork. This position is useful in climbing and sprinting situations, but will sag with the rider’s weight. The fork will 'blowoff' in the event that a big hit is encountered with the fork locked out.

To unlock the fork, simply rotate the lever fully counterclockwise.

Changing Travel

Travel on your FLOAT fork can be changed by rearranging the internal travel spacers. After changing travel, check the fork for proper operation before riding. If there is noticeable play in the fork or if it makes strange noises, disassemble the fork and check for complete number and correct orientation of spacers.

FLOAT forks can be reduced in travel, but they cannot be increased in travel beyond 140mm.

  1. Remove the blue air cap from the top of the left fork leg. Let the air out of the fork. Remove the left top cap with a 26mm socket 6-point socket wrench.

  2. Loosen the bottom nut 3-4 turns with a 10mm wrench. With a plastic mallet, gently tap the bottom of the shaft to disengage it from the lower leg. Allow oil to drain into a bucket. Remove the bottom nut and crush washer.

  3. Compress the fork as much as possible. The air piston will be visible about one inch below the top of the upper tube. Push the bottom of the air shaft upwards to push the air piston out of the top of the upper tube. Use a long, thin shaft screwdriver to push the bottom of the air shaft up through the hole in the bottom of the lower leg.

  4. Pull the air-shaft assembly from the fork. Refer to the drawings below and add or remove the appropriate number of 20mm spacer(s) to achieve the desired travel.

Spacers snap onto the air shaft between the negative spring guide and topout plate, as shown in the travel spacer orientation drawing below.

  1. Lubricate the U-cup seal on the air piston with FOX FLOAT Fluid and re-install the air shaft assembly into the upper tube. Be sure to orient the U-cup seal as shown in the Seal Orientation drawing below.

  2. Push the shaft until it approaches the bottom hole of the fork. Do not push the shaft all the way through the bottom hole.

  3. Turn the fork upside down. Measure and pour 30cc of FOX Suspension Fluid through the bottom hole.

  4. Push the air shaft assembly up until the shaft comes through the bottom hole. Install the crush washer and bottom nut. Torque to 50 in-lbs.

  5. Turn the fork right side up. Pour 5cc of FOX FLOAT Fluid on top of the air piston.

  6. Lubricate the o-ring on the air topcap with FOX FLOAT Fluid.

  7. Re-install the topcap and torque to 165 in-lbs.

  8. Pump up the fork to the desired pressure and cycle it several times to check for proper operation.

  9. Re-install the blue air cap.

  10. You’re done. Go ride.
