2 INSTALLATION

WARNING: Installation of NERO suspension forks requires specific knowl-

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

to correctly install the NERO 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 NERO 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 hydraulic 

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 compressed. 

-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 exces-

sive 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.
