Adjusting Rebound
The rebound adjuster knob 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 slows down rebound; turning the knob counter-clockwise speeds up rebound. As a starting point,
turn the rebound adjuster knob all the way clockwise (full in) until it stops, then turn counter-clockwise (out) 12 clicks.

Climb. Trail. Descend.
The blue CTD lever lets you to switch between the Climb, Trail, and Descend ride modes. Each mode is most suitable for each specific type of terrain, providing best performance and riding enjoyment with
your fork. With some experience, you can experiment with using Trail mode when descending, or Descend mode for flat or undulating trails.
NOTE:
With full CTD suspension, front to rear suspension balance is best achieved by running the fork in the same ride mode as the rear shock (Climb with Climb, Trail with Trail, Descend with
Descend).
Climb Mode
Rotate the CTD lever fully clockwise to set the fork in Climb mode, which is most useful for climbing and sprinting. In Climb mode, the fork will "blow off" in the event that a big hit is encountered. This
setting was formerly known as “lockout.”
Climb Tune Factory Settings
There are two pre-set Climb Tune mode settings offered for Factory and Performance model forks:
medium
and
firm
.
Refer to the Climb Tune decal located on the crown next to the CTD lever, to determine which factory pre-set climb tune your fork has:
Medium factory settings will be found on longer travel forks (130 mm travel and above for 26
forks, and 120 mm travel and above, for 29 forks)
Firm factory settings will be found on shorter travel XC-type forks
Climb Tune factory settings can only be altered through complete disassembly and re-bleeding of the CTD damper system. Contact your local dealer or FOX at 1-800-FOX-SHOX for more information.
Additional service information can be viewed at
NOTE:
The fork may cycle a couple of times after you engage Climb mode. Once complete Climb mode is achieved, the fork may continue to move 3 - 5 mm. This is normal, and does not affect
performance.
Trail Mode
Rotate the lever to the middle setting of the blue CTD lever to engage Trail mode. Trail mode offers significantly less compression damping than climb mode, which is good for a light pedaling platform when
pumping undulating terrain, and for preventing excessive travel in technical riding situations (such as low-speed drops).
Descend Mode
Rotate the lever fully counter-clockwise to set the fork in Descend mode, which is similar to Trail mode but with significantly less low-speed compression damping, for the softest ride when descending.
Adjusting Trail Mode
(FIT CTD Trail Adjust Only)
Factory FIT CTD Trail Adjust model forks feature a three-position Trail Adjust control that regulates low-speed compression damping only while you are in Trail mode.
NOTE:
While it is possible to readjust FIT CTD Trail Adjust when you are in either Climb or Descend mode, Trail Adjust changes will only be felt in Trail mode.
For a firmer low-speed compression setting in Trail mode, turn the black Trail Adjust dial clockwise. For a lighter setting, turn the Trail Adjust dial counter-clockwise.
TIP:
This setting is designed to work in conjunction with the rear shock, keeping in mind that front to rear suspension balance works best when the fork is in the same ride mode as the rear
shock.
