I'm building up a French bike (from 71 or 72). It currently has one cup (and is missing the left side. I forget which is fixed cup on a french). I can go out and buy a Sugino french threaded cup set and then use a typical spindle and bearing set up (cup-and-cone style)right? Because the only difference is threading, so that's the only thing I need to address. And the only threaded parts are the cups, right?
