Installing Your Fork

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 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 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 center blue aircap in the middle of the TALAS travel adjusting topcap on top of the left fork leg (shown below), to expose the Schrader valve.

    Note:  Hold the TALAS lever steady with one hand while unscrewing the aircap with the other. This will facilitate removal of the aircap and also protect the TALAS lever from being forced past its stops.

  2. Attach a FOX Racing Shox High Pressure Pump to the Schrader valve.
  3. Using the Air Spring Settings table below, pump your fork to the appropriate setting using the FOX High Pressure Pump, then remove the pump.  
  4. Install a zip tie with light friction on the upper tube and push it down until it contacts the fork seal.
  5. Carefully sit on the bike and assume a normal riding position. The fork should compress slightly.
  6. 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.
  7. 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.
  8. Screw the blue aircap back on, and go ride.

    Note:  Sag and spring rate will self adjust to the proper setting and rate as TALAS is adjusted to shorter travel positions.

    Sag Troubleshooting



    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 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.

Setting Description

Tuning Tips

Setup Tips


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.


(Factory setting)

Average 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.

Changing Travel

32 mm TALAS forks feature three externally adjustable travel choices per maximum fork travel specification. These travel settings are easily selected using the TALAS travel adjusting topcap on top of the left fork leg, as shown below. Travel options and direction settings are printed directly on the topcap:

140 mm
  • 5.50” (140 mm)
  • 4.75" (120 mm)
  • 4.00” (100 mm)

150 mm
  • 5.90” (150 mm)
  • 5.12" (130 mm)
  • 4.33” (110 mm)

Note:  When changing travel, the TALAS system automatically adjusts to provide you with the appropriate linear air spring rate for each travel setting. There is no need to change the air pressure in the TALAS air chamber after adjusting travel.

For safety reasons, it is recommended that travel adjustment be done while off the bike. If necessary, travel can be adjusted on-the-fly (be careful when using this "extreme" travel adjusting method), which can be handy right before a grueling climb or steep descent.
