Proper set up and tuning can vary from shock to shock. Please consult the FOX
manual included with your bike for complete information about set up, tuning and
To achieve the best performance from your FOX Performance Float X rear shock
you first need to adjust the air pressure to get the correct sag setting for you. Sag
is the amount your suspension compresses under your weight (in riding gear).
Sag should be set to 30% of total shock travel, which is 15mm for the Float X on
the Primer Expert. You can find this by measuring the distance between the sag
indicator O-ring and the rubber air sleeve seal (see opposite). We recommend
watching the sag setup video at
for detailed information on how to
set your sag correctly.
Use your own body weight in lbs as a starting point (if you weigh 180lbs, put
180lbs of pressure in the shock). When setting sag always turn the compression
adjuster fully counterclockwise and set the 2-position lever to the Open mode.
With the air pump attached to the shock valve, slowly cycle your shock through
25% of its travel 10 times as you reach your desired pressure. This will equalize
the positive and negative air chambers and will change the pressure on the
pump gauge. Do not exceed maximum air pressure of 350 psi. Add or remove air
pressure until you reach your desired sag measurement.

The 2-position lever is
useful to make on-the-fly

performance under significant
changes in terrain, and is
intended to be adjusted
throughout the ride. Use the
Open mode during rough
descending, and the Trail
mode for undulating terrain
and climbing.
