Old Peugeot, modern gear

Hi All, this is my first post so be gentle please.

I have what I think is an 87 Peugeot 12 vitesses frame on which there is absolutely no gear. I've spent a long time on the various threads and I think its 87 because of the number stamped on the frame (Y711).

My question is simple. Will it take a modern groupset? Everything I've read seems to indicate Peugeot changed from French to English threads etc in early 1980. So am I in luck? Will the almost new gear I've got fit ok? I've already expanded the rear of the frame to 130mm.

It should work if the bb shell is indeed English.

Even if the shell is metric thread (French or Swiss), you could make it work with a Phil cartridge and proper mounting rings, or a threadless cartridge. It's mostly a matter of how much money and effort you're willing to spend to make it happen.

My 1986 Peugeot PGN 10 has Swiss threading. It would take a good bike shop to determine it.

This is my Premiére - it's a 1986 bike. Bottom bracket and headset are British threaded, and I've expanded the rear dropouts to 130mm.

It's fitted with a Chorus chainset, Tiagra 9 speed brifters, and 105 derailleurs now - a purist's nightmare but a very nice bike to ride

Both 1985 PGN10's I've owned over the years both had British threading. At one time, my first PGN10 has modern components, such as Microshfft Arsis groupset, Shimano 105 crankset, and a decent wheelset after cold setting the rear.
