Hey all,

I've got a Cannondale F900SX with what I understand is an older Lefty fork (2001 or 2002 I think).

As best as I can tell the fork no longer holds air. If I pump it up to a comfortable level (pretty high - I weight 200lbs) it gets very spongy after a few days and will compress significantly when I put weight on it. When I attach the pump it shows 30-50psi in the fork - far less than I had pumped it up to.

I've done a search about rebuilding Lefties but it seems that most of the post and how-tos are for new style forks, not my older one. I'd like to do it myself.

Any help is much appreciated!

Older Lefties were more tool intensive than the new ones. You need new air piston seals, and most likely a full go through wouldn't hurt. If you want to spend $100+ in tools, many that will only work with that fork, go for it, but I'd suggest finding a competent shop, and let them handle it. Not saying you can't do it, but time, money and hassle factors suggest an alternate course :cool:
