I recently acquired a Ron Cooper track bike, very spiffy looking! Any info on this would be appreciated. It is yellow, 56c-t seat tube, full 531 tubeset, Campy pista gruppo. I would guestimate late 70s-early 80s? I could find no serial number. Looks to be almost unused. No drillings for brakes. This is my first fixed gear, although I wish it was set up for a front brake so I could ride it on the road!
