Fork Suspension Settings
Adjusting Spring Preload
Preload: The distance the spring is
compressed from its free length with the
suspension fully extended. It affects the
suspension sag.
1. On the top of both fork tubes, turn the hex
adjuster
A
equally to the desired setting. Be
careful to not loosen the screw caps
B
.
2. Zeroing: Turn the screw as far as possible in
a counterclockwise direction.
3. Turn the screw counterclockwise to desired
setting.
Initial Spring Preload Guideline:
6 clicks (3 mm)
Turning clockwise increases the preload;
turning counterclockwise decreases the
preload.
Adjusting Compression Damping
Compression damping: It controls the rate of
suspension compression.
1. On the top of the left fork tube, turn the brass
screw
C
to the desired setting.
2. Zeroing: Turn the screw as far as possible in
a clockwise direction.
3. Turn the screw as many clicks as necessary
counterclockwise to the desired setting.
Initial Compression Damping Guideline:
17 clicks
Turning clockwise increases the compression
damping; turning counterclockwise decreases
the compression damping.
Adjusting Rebound Damping
Rebound damping: It controls the rate of
suspension extension after compression,
known as rebound.
1. On the top of the right fork tubes, turn the brass
screw
D
to the desired setting.
2. Zeroing: Turn the screw as far as possible in
a clockwise direction.
3. Turn the screw as many clicks as necessary
counterclockwise to the desired setting.
Initial Rebound Damping Guideline:
10 clicks
Turning clockwise increases the rebound
damping; turning counterclockwise decreases
the rebound damping.
