FRONT SUSPENSION TRAVEL & SAG GUIDE
To determine bike's front suspension travel adjustments and recommended
settings, please refer to the fork manufacturer's technical manual.
A suspension fork is effective at both absorbing bump forces and helping the tire to
track the ground for improved traction and braking control.
When in active mode, a fork will rely on sag to keep the front tire in better contact
with the ground during braking. The chart should be used as a general guideline.
AIR SPRUNG FORKS
As a general guide, pump the main chamber (main spring) to a psi equal to 70% of
your body weight. Ride off a curb or similar object. If there is little or no movement
from the fork, decrease psi in 10-psi increments until desired movement is
achieved. If the fork bottoms out, increase the psi in 10-psi increments until desired
movement is achieved.
To check rebound, turn the rebound damping knob (if applicable) counter
clockwise until it stops. With full body weight, push down on the fork forcefully with
the front brake on and watch (and feel) how the fork rebounds. Turn the rebound
damping knob clockwise until the fork rebounds slightly slower than with no
damping (the heavier the rider, the more damping will be required).
SPRING AND ELASTOMER SPRUNG FORKS
Springs on these types of forks are set at the factory. Most have a simple adjuster
that allows the rider to make the fork firmer or softer depending on rider weight.
The heavier the rider, the firmer the spring setting should be.

*Manitou Forks with SPV may not sag upon initial rider weight. To check sag on an
SPV fork, inflate the main spring cartridge to 70% of rider's weight, and the SPV
cartridge to 30% of rider's weight (check the manufacturer's technical info for
details).
