nishiki frame..
im looking into picking up a '76 Nishiki international frame for what i think to be a decent price(dont really know what it's actually worth)..my basic intentions are to build it into a fixed or ss..the issue at hand is that i stand at a mean 5'6" maybe 145lbs and the frame is a 51.5cm and i fear that it might be small..what do you guys think?
