Spring Tuning on Vanilla Forx
Read the Vanilla Spring Tuning Guide chart below to see if you need to change your spring rate. Vanilla Forx are tuned by
changing only the left side coil spring. The coil spring has a painted color code stripe on one end of the spring.
Refer to the chart to select the optimum spring.

Vanilla Spring Tuning Guide
General Set-Up Instructions
Fork Terminology
Travel: The total amount the fork compresses.
Sag: The amount the fork compresses with the rider sitting on the bike in a normal riding position.
Compression Damping: This controls the rate at which the fork compresses
Rebound Damping: This controls the rate at which the fork extends.
Preload: The initial force place on a spring.
Spring Rate: The amount of force required to compress a spring one inch.
FLOAT: This is FOX air spring technology and is an acronym for FOX Load Optimum Air Technology.
Vanilla: This is FOX coil spring technology.
TALAS: Travel Adjust Linear Air Spring.
Vanilla Forx
Setting Sag on Vanilla Forx
To get the best performance from your FOX Vanilla fork, it is necessary to set and adjust sag. Sag is how much the
fork compresses or “sags” when the rider sits on the bicycle. Generally, this is 15-25% of the total travel.
Measuring and adjusting sag
1. Install a zip tie on the upper tube and push it down until it contacts the fork seal. Carefully sit on the bike and
assume a normal riding position. The fork should compress slightly. Being careful not to further compress the fork,
dismount the bicycle. Measure the distance between the seal and the zip tie.
This distance is the sag.
2. Compare your sag measurement to the table:
If your sag is lower than on the table, turn the preload knob
counter-clockwise one (1) full turn. Measure sag again and repeat
adjustment if necessary.
If your sag is higher than on the table, turn the preload knob clockwise
one (1) full turn. Measure sag again and repeat adjustment if necessary.
If correct sag cannot be achieved by adjusting the preload knob, see the Spring
Tuning Guide below.
