All French, Right?

Looking for confirmation here. I've got wheels from a parted out PX-10 which I'll be using on the PX-10 I'm building: Normandy Luxe Competition hubs (gold foil labels), rear has a groove between the threads and the flange. The freewheel is a 14-21 Cyclo Competition with no indication of the threading as far as I can tell. ISTR reading recently that the groove indicated French threading, but was hoping for something more definitive than my sometimes faulty memory, like actual printing. Thx...

Try the Cyclo freewheel on an English threaded hub. Or try an English threaded freewheel on the Normandy hubs. It should be apparent if it's French or not. Just make sure you have freewheel remover for the type freewheel you are testing. A French freewheel will start to thread on an English hub but then gets really tight. English freewheel will be really sloppy on french threads.

Or thread a known, English thread bottom bracket lockring onto the hub. If it threads on smoothly, but without slop, the hub is English thread.

Thanks for the responses. Several options. I'll get it figured out this weekend.

My original 1972 PX-10 Mavic rear wheel with the Normandy hubs accept a standard ISO freewheel no problem. I just tried it and it goes on like butter and it has a grove. To quote Sheldon Brown's website "virtually all French bicycles sold in the U.S. had standard British/I.S.O. freewheel threads"

Thanks, confirmed that when I got home as well. I have a drawer full of bb lock rings. I found one which fit on a Tange Seiki cartridge bottom bracket. It fit on The hub just fine. So ISO it is. Now I just need to find a 14-28 freewheel to replace the narrow range Cyclo.

I have a new old stock Regina Oro 14-28. But I doubt you'd like the price.
PM me if interested.

Memory is finicky that way. The groove indicates British thread.

@jcb3 and @smontanaro So you found that the freewheel threads for both of your PX's are English threaded? I pray that is the case with my upcoming PX build. The original freewheel is just not suited for the hills around here.

I think of all the French bikes Gitane was the one that fervently spec'd french threading on its parts. The early 70's TDF's had french threaded Campy Tipo hubs. The bikes equipped with Sugino cranks also had french pedal threads.

The Stronglight crank and Lyotard pedals are French threaded. I could swap the Stronglight crank for British threaded one, but decided to leave it as-is, to force me not to cheat and put clipless pedals on it.

No doubt. Nothing else is new on this build. It would look so out of place...
