I am trying to find out info on the GT brand road bikes. I have been unable to find a thread about GT on this forum, or maybe just missed it. If anyone has info on these bikes, I would appreciate direction to a thread or just your input on them. I am looking at a GT road bike with down tube shifters. Haven't seen it in person yet so no info on date of manufacture. I suppose mid 80's? Any recommendations on GT bikes in terms of quality and value of that vintage would be greatly appreciated.
