Thanks for the info, SK. My rear shock seems to be operating fine; I'm really light at 105 lbs so don't put a lot of impact on it, and the LBS that inspected it last year said it was fine, so I'll probably hold off on any more expense right now, because I just won an auction for a 2005 Fox F80X fork on ebay tonight that I'm excited about. I can't wait to have lockout, and it looks to be in great condition and certainly much newer technology than my old Rockshox, for not much more $ than rebuilding my fork. I needed an 80 mm fork for my frame geometry, and those are kinda hard to find these days, so hopefully I got a decent deal -- based on the comps I found from completed auctions and others for sale online brand new, I think I did ok (see auction link).

Thanks again,
Emily
