It seems to me that modern Crescents within our general timeline would all have been metric (French) threaded. Perhaps an American made one from the very early days, before it became a Swedish firm, would take something different.

Of course, someone may have fitted a replacement fork with a ton of rake in an attempt to quell the epic toeclip overlap on those bikes. I believe Mike Kone characterized it as "...foot in the spokes" TCO in the guide residing on Sheldon's site.

They are still cool bikes even though they may have had even fewer (and duller files) on the factory floor than the Peugeot factory. I think I've only seen one example where the Nervex Series Professionel lugs had been cleaned up - listmember Chris Schultz owns it and it is a beauty.
