–
Smaller differences in the rider's weight can be compensated for by the fork air
pressure.
–
However, if the fork frequently bottoms out (hard end stop on compression), the
fork air pressure must be increased, within the specified values, to avoid damage to
the fork and frame.
–
If the fork feels unusually hard after extended periods of operation, the fork legs
need to be bled.
