Step 1

Make sure that your fork is ready to ride

1. 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.

Step 1

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

1. Unscrew the blue air cap on top of the left fork leg to expose the Schrader valve.
   
2. Attach a FOX High Pressure Pump to the Schrader valve.
3. Pump your fork to the appropriate starting point 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, temporarily install a zip tie to an upper tube. Slide the o-ring (or zip tie) down against the scraper lip of the fork dust wiper.
   
5. Rotate the CTD lever to the Descend mode (the riders 1 o'clock position).
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 blue air cap on clockwise until snug.

Step 1

Rebound controls how fast the fork extends after compressing

The red rebound adjuster is located at the bottom of the right fork leg. Rebound controls the rate of speed at which the fork extends after compressing. Turning the knob clockwise (in) slows down rebound; turning the knob counter-clockwise (out) speeds up rebound. Rebound damping should only be set after first setting your air pressure by measuring sag.

1. Make sure your CTD fork is in Descend mode (fully counter-clockwise).
2. Starting with the rebound adjuster fully open (counter-clockwise) push on the fork to compress it and feel its return speed.
3. Increase rebound damping by turning the red rebound knob in clockwise 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.

Step 1

Easy on-the-fly adjustments for unprecedented control and performance

The blue CTD lever lets you to switch between the Climb, Trail, and Descend modes. Each mode is optimized for each specific type of terrain, providing exceptional performance and riding enjoyment with your fork. CTD allows for complete rider control as one can experiment using different modes on various different types of terrain.

Climb Mode:

Rotate the blue CTD lever fully clockwise to set the fork in Climb mode. Climb mode is a very firm low-speed compression setting (not designed to be a solid lockout). This setting is most useful for climbing and sprinting.

Trail Mode:

Rotate the blue CTD lever to the middle setting to set the fork in Trail mode. Trail mode offers less compression damping than Climb mode. Use this setting when pedaling on undulating terrain, and for preventing excessive travel in technical riding situations (such as low-speed drops). Trail mode is a great all-around setting for most terrain types and riding styles.

Descend Mode:

Rotate the blue CTD lever fully counter-clockwise to set the fork to Descend mode. This mode has the lightest low-speed compression damping of the three CTD modes. Descend mode offers the most plush ride to ensure optimal traction over varied terrain.

Step 1

FIT CTD w/Trail Adjust models allow for added fine tuning

Factory CTD w/Trail Adjust model forks feature a three-position Trail Adjust control that regulates low-speed compression damping only in Trail mode. For firmer low-speed compression in Trail mode, turn the black Trail Adjust knob clockwise. For lighter low-speed compression, turn the Trail Adjust knob counter-clockwise.

Trail adjustments (soft, medium, firm) only function in Trail mode.

Step 1

You can adjust the travel of most 32mm FLOAT forks by 10mm increments. Most forks can have their travel shortenend, but only select few models can have their travel extended. 

As many 32mm FLOAT forks have been built with slightly different internal air spring systems, your fork may appear different than that shown. To make sure that you are prepared with the correct travel adjust parts specific to the fork that you are working on and that your fork model can be travel adjusted, FOX recommends that you first take note of your fork's serial number and 4-digit product code, then contact FOX US at 1.800.369.7469, email [email protected], or contact an Authorized International FOX Service Center at ridefox.com/GlobalDistributors »

Make sure to properly maintain your fork

Step 1

Maintaining your fork is key to good performance on the trail. This video guides you through the process of changing your bath oil, dust wipers, and air seals to reduce friction and prevent wear.

As many 32mm FLOAT forks have been built with slightly different internal air spring systems, your fork may appear different than that shown. To make sure that you are prepared with all of the replacement parts specific to the fork that you are working on, FOX recommends that you first take note of your fork's serial number and 4-digit product code, then contact FOX US at 1.800.369.7469, email [email protected], or contact an Authorized International FOX Service Center at ridefox.com/GlobalDistributors »
