Help ID Vintage Road Bike
Okay, so I actually know the name, but I don't know much about it. It is a Concord Joplin bike made in Japan, I picked it up for next to nothing. It appears to be somewhat typical 70s bike boom era. I dont get the impression that it was expensive because it has a Shimano Eagle Derailer. Other features are Dia-Compe center pull brakes, lugged frame, chrome tipped forks, shimano hubs. It is filthy, but in nice shape, almost zero scratches. Is this bike worth fixing, what might I be able to sell this for. Any info helps. Thanks!
