This is an ’83 Trek 500 frameset that I am trying to mod into a 9 spd. The crank isn’t 9 spd, but it seems to shift fine up front on the stand. Once I have the bike running, if the FD shifting is rough, I’ll get some ramped and pinned inner rings. I’m getting ready to take the frame to the frame builder. Hopefully he will be able to swing the rear triangle back into straightness.
