my weight is 50kg and using 04 sid race
my fork have about 5-8mm of sap
i use about 60+mm of travel on certain bump.
and when i hit another bump that i thought is much harder than the previous one, the travel i use is only low 70mm.
until now, i have never bottom out no matter how hard is the bump.
i feel that the fork cant be compressed anymore (i thought it have bottom out)
but it have not bottom out yet.(more than 70mm but less than 75mm)
so, is it impossible to use up the 80mm?

what are your air pressures? (positive and negative)

A riding buddy of mine is around 60-65Kg, has an '01 SID Race and I think he's running around 100psi pos/110psi neg, so try a bit less than that.

Also, if you have the compression dialled on, they will not be very plush either.

yes it's designed that way - it's an XC race fork, designed to be light and not plush.

But, my friend's is working pretty well on the rough trails we ride, after dialling in his air pressures and damping.

If you want to check a fork to make sure it can use full travel, reduce the positive pressure until you can compress it fully, then add air until sag and ride is what you want. If it won't compress even with low air pressure, then it may need service or repair.
