I have a chance to pick this up in a trade, Don't know a whole lot about light weight bicycles, try to avoid them most the time but this one seems really clean. Any ideas on age?
"Vista was a brand started by a group of bicycle dealers in the 1960's. The early bikes were made by Columbia. Later, Vista's were made in Japan."
I think you have an Japan made bike, because the American made frames were all probably the standard non lugged style. The Vistas I've seen are Columbia frames, same dropouts and everything.
