French Campagnolo?

So I’m looking at a complete Campagnolo Nuovo groupset that came off a French bike, which I plan to fit on my Raleigh Team. Now I know there’s always problems with BB threading etc, but no amount of internerd searching gets me info on variations and interchangability of campy groupsets between countries.

My initial assumption is that groupset models would stay the same across the board, but I can’t be sure. Is anyone storing this secret knowlege from ages past? Or am I just an idiot who can’t use a search function?

And just in case it helps, the bike in question is a 70s Mercier of 531 tubing.


Yes, Campagnolo was made with Italian, English and French threadings/sizes.

Thankyou Spirito. I thought it seemed too easy :frowning:
