Just bought a grail of a bike from a friend on Friday. Full Shimano 600 with original barcon shifters.

Bridgestone’s RB-1 is a highly sought after bike. Grant Petersen of Rivendell cycles designed bikes for Bridgestone in the 80’s. The RB-1s and XO’s are some of the nicest frames to come out of the Bridgestone name before Bridgestone Japan canceled the domestic branch.

I think I may put some mustache bars on it and keep the 28c tires.

Edit: I threw an extra Cinelli 1a stem on it with some Cinelli Priest bars… just need some bar tape now!
