Hi
jimijames. I have been putting together a 1978? Competition and was trying to convince myself that I could ride it even though I prefer a 60cm seat tube. It is a 58cm ST. Turns out though, the top tube is 56cm which I definitely would be scrunched up on. Anyway have a look at this photo and PM me if you are interested. No rust but definitely has patina (scratches and wear marks). I am in Ontario.
