thanks for the info guys. i found the manual for it, its a 1998 SID. figured out how to air it up and the manual said to use a football needle which i happened to have. brought it up to 60 psi like it said for my weight and its much better now. have a few mm of sag as opposed to the 25mm it had before and it seems to be holding. going out to Oleta tomorrow and hopefully it'll feel better and not bottom out everywhere.
