It's on Craigs and the details from the seller are>> it's a men's bike, I am 5'10" and ride it, the picture shows everything and the tires need air. He wants $100.
If it is actually an early to mid 70's 531 framed Super Course in good shape I am guessing that is a good price for a keeper if it fits. Frame looks really big. If that is a Brooks saddle on it that's a plus.
I can go see it in the morning and it's close by.
