2 INSTALLATION

WARNING: Installation of THIRTYFIVE suspension forks requires specific knowl-

edge, equipment and expertise. General mechanical skills are not sufficient to 

correctly install the THIRTYFIVE suspension forks. 

Formula strongly recommends that a qualified service center authorized by FORMULA 

install the fork on your bicycle. Improperly installed forks can cause damage to the 

THIRTYFIVE suspension and serious injury or death. 

- Formula does not authorize the end user to install the fork on the bike. 

WARNING: Failure to follow these guide-

lines may result in serious injury or death. 

2.1  Installing the hose clamp

- Secure the disc brake hose to the fork with clamp (

8

).

- Loosen the screw (

9

) and move the clamp over the hose 

(

8

).

- Insert the hose inside the hose clamp (

8

).

- Tighten to 2/3 Nm.

3 USE

GENERAL SAFETY NOTE: Do not keep the 

fork fully at the end of the race for a period  

 

exceeding 10 days.

 

If that happens you can verify that the hy 

 

draulic system is not working properly.

3.1  Suspension Adjustments

- Use the rebound adjuster (

10

) to adjust how quickly the 

fork returns to its extended position after being com-

pressed. 

- Correctly setting the rebound speed allows the bicycle 

to properly track the terrain. 

-  Rebound that is set too fast will cause the fork to feel springy and uncontrolled and exhibit 

excessive return speed

-  Rebound that is set too slow will not allow the fork to extend quickly enough to prepare for the 

next bump.

- Turning the adjuster (

10

) clockwise (toward the + sign) adds hydraulic damping and slows the 

rebound speed. 

- Turning the adjuster (

10

) counter-clockwise (toward the - sign) removes hydraulic damping and 

speeds up the fork rebound speed.
