–
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 oper-
ation, the fork legs need to be bled.
