5.2 Initial suspension bottoming adjustment

The SAG corresponds to the forks sinking due to the rider's
weight.
How to measure SAG
In order to measure the SAG, you only need to carry out the
following steps.
• On the leg portion of the fork, measure the distance
between the lower crown and the dust seal (see A in
Picture 8). Note this value as "H1".
• While sitting on the bike, repeat the measurement (see B
in Picture 8). Note this value as "H2".
How to fi nd the best SAG
The best SAG for Cross-country forks is 15–20%, and for
Freeride forks is 25–30% .
In order to calculate the best SAG for your own fork, you will
need to make the following calculation:
T = total travel
S = suggested sinking percentage.
The best SAG is obtained by varying the spring preload
(spring fork legs) or by varying positive air pressure (air fork
legs).
For the fork legs with SFA or ETA cartridges, the adjustment
of the initial sag is carried out by varying the SFA/ETA
chamber pressure.
• SFA see par. 5.3.1.1.
• ATA see par. 5.3.8.1.
