Well my experience is different. I find an Italian or English FW will en gage a French hub. It will be loose, anywhere from obviously loose to ju st a little loose depending on the particular FW and hub. A French FW wi ll, in may experience alway start on an English or Italian hub, and will us ually go maybe three turns before it really starts to tighten up. It wou ld usually be possible to run a French FW all the way onto an Italian hub u sing an FW tool and a wrench if one were foolish enough to do so.

Whoops! My mistake; Campy only marked English threading; French and Italian are unmarked but readily distinguished by the 1mm difference in diameter (35mm=French, 36mm=Italian). An Italian freewheel will not engage a French thread hub at all, and a French freewheel is to small to even start on an Italian thread hub.
