I think the BB is a Sakae 36mmx24tpi but later I am gone check that.


If that is so it looks like it might be an Italian frame after all, as mdvineng says. Probably a Piazza!

Yes your frame which looks very similar to mine has different fork ends and it seems different threading of the bottom bracket.

nunojoao- Do you know whether the bottom bracket threads on this frame are French (35mm x 1mm) thread?
Or Italian thread (36mm x 24tpi)? Or Swiss thread?

From Sheldon Brown:
"Some French bicycles, notably many Motobécane models, used Swiss thread bottom brackets.
These have the same thread and diameter as French, but use a left thread for the fixed cup."




The thread might be inscribed on the BB cups, if you still have them.


I think the BB is a Sakae 36mmx24tpi but later I am gone check that.


After I remove all the rust I saw that the BB is 35 mm x 1 mm.
For that reason it’s a french thread.

In that case, the question that occurs to me, is:
Would Piazza be making frames with French thread (and Nervor steerer, and RGF BB shell) for the French market, at a time when Campag. 'short' dropouts had been around for long enough to be copied by others? (say 1978 earliest?)

That is a good question. I am gone to research on the web and see what I get

35 x 1 could also be Swiss, which would have a left-hand-threaded drive-side cup on bottom bracket. I mention this because I recently saw an eBay auction (from Poland) for a Mondia frame that had Piazza dropouts.
