I got an old lugged Trek today. I measure it at 51cm center to center, but I think it is a 52 Trek measurement. 54 toptube. Requires clamp almost everything. Reynolds 531 tubing, decal is torn. Paint has multiple chips. Light silver blue. I have some of the clamps for the cable routing and the original (?) what I would call entry level alloy parts from the late 70s. Frame/fork/hs/bb shipped for $65 if you can use it. Parts availble, cheap, if you want them too. Wheels are Nisi rimmed, hi-flange clinchers. Email me direct for more details.
