3. Compression Damping - The compression
damping is adjusted by turning a screw on the
bottom of each fork leg. There is a rubber dust
cover protecting the screw and a jam nut (C)
securing the screw (D). The adjuster has 12
stages of adjustment. Turn the adjuster clockwise
for slower compression. To speed up
compression, turn the adjuster counter-clockwise.
Start with a middle setting and fine tune the
compression from there. Proper compression will
allow 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 bottoming-out stops. Adjust each fork
leg evenly. Replace the rubber dust cover after the
adjustment.

Note: Adjusters should never be forced completely
“Fast” or “Slow”; always leave one click of adjustment
in either direction.
