Heh, heh... I just got home with it. I haven't measured yet but depending on how you measure it just might be a 57.

The bike is in beautiful shape considering... birthdate is 0730, so it's an '80, right? Needs a rear tube and the hoods are all cracked & wonky. Anyone have a line on a cheap pair of hoods? They're Dia-Compe drilled levers.

I'm anxious to get cracking on it tomorrow.
