I’ve got the above pair of forks and am struggling with air pressure.

I’ve used the FOX chart to setup the air pressure to my weight (14 st 5lb) and they just bottom out, Ive got to put much more in than what the chart states.

The oil levels are accurate and there are no leaks (oil or air). What does this suggest? Do springs deteriorate with time? Am I missing something simple?

Thanks in advance,

Dave.
