AUTOSAG AIR SHOCK SETUP
Levo FSR bicycles are equipped with AUTOSAG, a unique new feature designed to simplify and speed up the
adjustment of air pressure. The AUTOSAG feature automatically determines the correct amount of sag, and
eliminates the need to refer to an air chart to determine the correct pressure based on rider weight. However, the
shock still requires compression and rebound adjustment based on type of terrain and rider weight. Once the air
pressure is set, please refer to the compresson settings (
).
Air pressures, rebound and compression settings are suggested starting point recommendations
only. They should be adjusted according to the rider’s needs for each type of terrain to achieve
optimal performance. Shock air pressure can be set up manually to rider preference instead of
using AUTOSAG if desired.
SETTING AUTOSAG

1.
Position the shock compression lever or knob (blue) to the full
open or off position
1
. Remove the positive air valve cap (black)
and the AUTOSAG valve cap (red).
2.
Attach a high-pressure shock pump to the positive air valve
2
,
then inflate to 300 PSI.
3.
Make sure you are wearing all gear that would normally be worn
on a ride (shoes, helmet, hydration pack if used, etc.). Mount the
bicycle, prop up against a wall, and sit in the saddle in a normal
riding position. Do not set sag while riding.
4.
Press the AUTOSAG valve
3
. Air will release as the suspension
settles into its pre-adjusted sag point. Make sure all the air is out
and release the valve.
5.
Cycle the shock a few times
4
, then dismount the bicycle.
6.
Do not depress the AUTOSAG valve again, otherwise the proper
sag setting will be lost, and will require this procedure to be
repeated from step #2.
7.
Put the positive air and AUTOSAG valve caps back on.
Do not exceed 350psi before activating the AUTOSAG valve (this is a starting pressure only). After
the AUTOSAG is activated, Fox recommends a maximum working pressure of 300psi when riding.
If the pre-sag air pressure is too low, the AUTOSAG button may let air out of the negative chamber,
which would result in incorrect sag.
Sag is measured as the distance between the o-ring and the shock body’s seal, after the rider’s
weight has been applied to the bicycle, with no bounce. When AUTOSAG is correctly set, sag
should measure approximately 20-30% of stroke, depending on riding/terrain experience. If
the rider is approaching 300lbs, AUTOSAG may not function, and sag may exceed the bicycle’s
prescribed amount.
ADJUSTING COMPRESSION
Fox DPS shocks are equipped with a 3-position lever for on-the-fly adjustments of the shock performance under
significant changes in terrain, and is intended to be adjusted throughout the ride.
OPEN:
Optimized for the perfect balance of control and plushness for steep, aggressive descents.
•
Factory Series shocks are equipped with the “OPEN MODE ADJUST” feature, with 3 additional fine tuning adjustments.
•
“Open mode adjust” is useful to control shock performance during rider weight shifts, G-outs, and slow inputs.
•
Lift the adjuster, rotate it to the 1, 2, or 3 position, and press it in to lock the position. Fox recommends making these
adjustments with the 3-position lever in the Medium or Firm mode.
•
Setting 1 will have a more plush feel and setting 3 will have a firmer feel.
MEDIUM:
Moderate for an optimal blend of pedaling efficiency and bicycle control on variable terrain.
FIRM:
The firmest setting for maximum pedaling efficiency.
