Spring Preload Adjustment
The spring preload is adjusted by turning the 19 mm
anodized hex nut (B) located on top of the fork spring.
Note: When adjusting preload, always start from the
minimum setting and adjust each fork leg evenly.
•
Turning the adjustment nut clockwise increases the
spring preload and reduces sag of the front
suspension.
•
Turning the adjustment nut counter-clockwise
decreases the spring preload and increases sag of the
front suspension.
Rebound Damping
The rebound damping is adjusted by turning the slotted
adjuster screw (A) on the top of both fork legs. Next to the
screw are the letters “H” meaning
Hard (slower rebound)
and “S” meaning Soft (faster rebound). The adjuster has 9
stages of adjustment. This determines how quick the fork
returns to its extended position after being compressed.
•
Turning the rebound adjuster screw clockwise slows
the rebound speed down making it better for larger,
rolling terrain or bumps.
•
Turning the rebound adjuster screw counter-clockwise
increases the rebound speed making it better for
smaller, rougher bumps. Adjust each fork leg evenly.
CAUTION: Adjusters should never be forced completely
“Soft” or “Hard”; always leave one click of adjustment in
either direction.
