This costs a bit more than your $10 Shimano cartridge, but it's French thread.

They also ship pretty fast. I ordered that exact BB Thursday and it came in today (Monday). I'd prefer something rebuildable, but I want to ride more than I want to buy a donor bike that's I'd have to shoehorn into my apartment. It screwed right in and seems nice. It doesn't work with a normal spanner style wrench though. If you buy that you will need Park Tool's BBT-22 or equivalent.

The real deal is what we've just told you - it's not a PX-10, it's a UO-8. Some people love UO-8s, some don't. $50 is a great price. Some like the way UO-8s ride just as they are. It's a very good quality bike for a late '60s/early '70s entry-level French bike, hundreds of thousands were sold back then, competing with Schwinn Varsity and several Raleigh models. Not a bad bike by any means IMO, but not anywhere near as good as a PX-10.

Replica? it's a REAL UO-8.

holy cow .

Becuase, alas, it often does.

The French cups in both the UO8 and PX10 are thin walled. The most common spindles you find require a thick walled cup. Unless you have some old Nervar/Stronglight spindles (and cranks) it's best to just replace the BB cups to Japanese, as it greatly widens your crank options.

I will note on my PX conversion I have thin walled Zeus cups and a Stronglight spindle; but on my UO8 conversion I have a Sugino crank and BB. You can do it either way, but the Japanese cups, spindle and cranks are just far more common. I will also note some 70s Japanese cranks and spindles play well with their French counterparts; for a list, see a period edition of Sutherland's.
