I've looked all through my manual, but no where can I find the following: a) Proper free sag (race sag is 90-100mm according to the book). Where the actual adjusters are for the rear shock. c) What high speed compression dampening affects. I've figured out by doing a search in this forum that the low speed compression dampening is the screw inside of the bolt, and that the bolt is the high speed compression dampening. I haven't been able to find out where the rebound dampening is though. And I haven't the fogiest idea what types of terrain affect low speed or high speed compression. Can someone shed some light on this for me? Thanks, M.
