Clutch – Clutch Preload Adjustment

Adjusting the preload on the clutch spring will shorten the
overall spring length, increasing the amount of force needed to
activate the clutch initially. Doing so will keep the clutch curves
the same but change the initial power required to activate it.
Adjusting the clutch preload can be done in three (3) simple

1. Turning clockwise, loosen the uppermost thumbnut, which
locks the lowermost thumbnut in place. It is the one
closest to the pedal itself

2. Adjust preload on the spring by turning the bottom
thumbnut (in contact with the spring):

a. Counterclockwise to tighten the preload, making the
clutch require more force to engage.

b. Clockwise to reduce the preload, making the clutch
require less force to engage.

3. Turn the uppermost thumbnut counterclockwise to
retighten it, locking the bottom thumbscrew in its position.

4. Recalibrate your clutch in RaceHub®.

Attention: Remember to adjust the pedal stop, to make sure the pedal arm rests on the pedal stop and not
the spring.
