wow, yea ours are the same except yours is a triple. The frame is a 56 CM. and boy, it is sun faded compared to yours.
The guy i bought it from didn't take much care for it because that thing is filthy, and rusty. The crank is loose, and i believe it might be missing
a bearing because it wobbles.. hopefully the LBS can determine what is wrong. How does it ride? i bet smooth.
