Fox Rhythm Fork Setup

This article is from the Fox website, but wanted to repost for future reference/archiving.

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

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

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 blue 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.

Rotate the 3-Position lever to the Open mode (the riders 1 o’clock position).

    • If you have a Remote fork, click the black release lever once to set the fork to Open mode.
    • If you have a Terralogic® fork, turn the blue Terralogic® threshold adjust knob fully counter-clockwise.
  1. 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.
  2. While in your riding position, slide the o-ring (or zip tie) down against the fork dust wiper.
  3. 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.
  4. Add or remove air pressure until your sag measurement is between 15-20% of your forks total travel.
  5. Repeat steps 2-8 and recheck sag measurement.
  6. When sag measurement is correct, screw the blue air cap on clockwise until snug.
