I must know what size BB to order for this bike. It is a 1984 nishiki international. The BB shell is 70mm wide. I measured with the cups and everything removed and I am positive this is the measurement. The right side (fixed cup) unscrewed clockwise, and the left side unscrewed normal (counter clockwise). It seems that every 70mm BB is itailian thread, but all the local bike shops tell me that I am crazy and that it has to be either 68 or 73mm. I want to order one soon as I prefer commuting on my bike, but it is out of commission right now.
