got a pair of marz 55 ETAs a couple of weeks ago, damn good price, anyway ive only had one outing on them and im still messing about with em to set them up right.

what i cant get my head around is the TST adjuster, on top of the red TST adjuster is a gold micro adjuster which is obviously the compression damping, but i cant fathom what the red sliding TST adjuster does, anyone shed some light on the subject?

also is there an air pre-load chamber on these forks? the instuctions written in 500 different tongues are rather poo...
