IMPORTANT NOTE ABOUT FORKS
ON ALL OUR BIKES
For the best possible performance, be sure you
are using the proper offset fork.

FORK SET-UP INFORMATION
Read this first for a general understanding of fork
set-up or skip straight to the air pressure charts
(page 31)
if you just want to go ride.
POSITIVE PRESSURE
This is the main air spring that supports your weight.
Adjust the air pressure so that you come close to
using all the travel on a typical ride. Usually you can
mimic your maximum impacts by grabbing the front
brake and pushing down
HARD on the bars. If you are
getting 80–90% of the fork’s travel doing this, your
positive air spring is in the right range. Actual riding
will often push the fork a little further than this test.
LOW SPEED COMPRESSION DAMPING
Low speed compression damping is used to reduce
unwanted movement and over travel due to low speed
changes like out of the saddle pedaling and subtle
variations in the trail that can cause wallowing etc.
It also helps control frame geometry change during
braking and cornering. Adjust to your preference.
LOCKOUT
As the name implies this turns the fork rigid (or
close to it) for out of the saddle efforts or riding
on the road. Most forks have a “blowoff” so that
the fork will move if a large enough impact is felt.
The threshold or “blowoff” when the lockout lets
the fork start to move is often adjustable. It’s
called Gate in Rock Shox parlance and Blowoff
Threshold in Fox’s language. Usually the goal is to
have the lockout at the minimum setting needed
to stop the fork movement while pedaling out
of the saddle, but allowing it to still move fairly
easily when an impact is felt.
HIGH SPEED COMPRESSION DAMPING
If your fork has a high speed compression
damping control, this would usually be used
to slow things down during big hits to avoid
bottoming. It would usually be set at the lowest
level needed to avoid bottoming out.
REBOUND
Adjust the rebound so that the front end does not
bounce off the ground after a drop off or large
bump. If adjusted too slow, the fork may “pack
down” and feel sluggish. In order to conserve
momentum and remain compliant the suspension
needs to recover fairly quickly and push off the
back side of bumps and holes. If the rebound
is adjusted too slow, rolling energy is lost to
damping and vibration. If it is adjusted too fast
the bike will bounce after bumps and drops.
Adjust to your preference.
