Checking the basic setting of the fork
Info
For various reasons, no exact riding sag can be determined for the fork.

–
As with the shock absorber, smaller differences in the rider's
weight can be compensated by the spring preload.
–
However, if the fork frequently bottoms out (hard end stop on
compression), harder springs must be fitted to avoid damage
to the fork and frame.
–
If the fork feels unusually hard after extended periods of oper-
ation, the fork legs need to be bled.
