ok, so compression is how fast or slow spring compresses when u hit a bump. rebound is how fast or slow the spring returns to original shape after a bump. preload is the "X" factor , the variable...my wt.
i must be too lite cuz when i adjust the preload i dont notice much difference at all. i set everything to low and i jump on the bike with all my wt and str. and i can probably drop it about,.... wait,does the entire silver part of the fork disappear when it bottoms out. i forget what the silver part is called. there's a name for it, the shiny smooth silver part the goes up and down. does steerer sound rt??? hmm ill have to measure it. 100mm is about 4inches i think.
thanx for the replies and help everyone. man, good thing i dont have a FS , just front fork is hard enough for now, lol.
