My buddy wanted to get me into mountain biking and lent me an old bike he had from the 90's. After about 8 rides I'm completely hooked but the front shock is pretty much dead. I was hoping someone here could help me identify it so i can see if its rebuildable. thanks

It's an old SID. Air shock, so you'll very likely need new o-rings/seals inside, and if it's that old, may need bushings as well.

Doable, but you're into some work and money to find some of the stuff. Plus, those forks are wet noodle flexy as well from the start.

IMO you'd do better off to just ride it and save up for a new fork or bike all together.

Are such parts available for old forks? When I had a Manitou Pro that needed something new after sitting around for 5 years (it would make a clunk sound on the return stroke), three shops told me they couldn't get the parts needed to repair it. Since it rode just fine and only showed its problem when jumping off something, I just kept riding it.

+1 . It's an old Sid with 28mm stanchions, as opposed to the now-standard 32mm and 36mm standard stanchion diameters.

Hope you know that it's an air fork. If you haven't already, you should air it up. If it's first generation SID, then you will need a special adaptor to screw on the end of of your shock pump. It's a Problem Solver's QBP part if you need to order one from an LBS.

A SID with a 36mm stanchion, that would be interesting...

Fwiw https://www.hippiesuspension.com/hippietechsuspension/ might be on option if you want to pay someone to service it, don't think they sell their parts, though.

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.
