Hey guys, I have a vintage (vintage to me at least) Bridgestone RB2 Syngergy. I will post pictures for anybody who wants to give some advice to help me fix it up, I'd say a 54cm frame, front derailleur, rear derailleur and shifters are all Shimano 400EX, Brake levers are Shimano 300EX. The crank is a Sugino DAC; 53 x 40. Any help will be gladly appreciated.
