Compression Damping
The compression damping is adjusted by turning a screw
on the bottom of each fork leg. Next to the screw are the
letters “H” meaning
Hard (slower compression) and “S”
meaning Soft (faster compression). The adjuster has 12
stages of adjustment.
•
Turn the adjuster screw (A) clockwise for slower
compression.
•
To speed up compression, turn the adjuster screw
counter-clockwise.
Start with a middle setting and fine tune the compression
from there. Proper compression allows the tire to track the
ground over consecutive bumps. Compression that is set
too slow will pack-up (feel harsh over consecutive bumps)
while compression that is set too fast will cause the fork to
bottom out harshly. If the fork is bottoming out, turn the
adjuster one click at a time until the bottom-out stops.
Adjust each fork leg evenly. Replace the rubber dust cover
after the adjustment.
Note: Adjusters should never be forced completely “Soft”
or “Hard”; always leave one click of adjustment in either
direction.
