Not sure what brand of 1970's 10 speed I have
I have a 10 speed bike from the 70's era, 1977-ish that has been professionally repainted but I cannot determine what brand it is. There are a few details that I can give that might give some clues. First, the serial number is S2110C461, which is on the underside of the bike frame. It also has the end shifters, which are SunTour, as are the brakes. The handlebar shaft says Arai, and there are plaques that say SunTour going down the frame as well as a holder for a tire pump. The derailers seem to be Shimano. The original color was a beautiful medium red. That's about as much as I can tell you. If someone has any ideas I would really appreciate your input. Thanks!
