seatpost: 26,2 mm, but it seems there is wrong size mounted, it does not fit well, the bolt must be pretty tightened to hold, I suppose the right diameter must be at least 0,2 - 0,4 mm bigger, I'm sorry about that, can't measure it any more accurate
Somehow, 26.4/1" doesn't jive with Nervex Pro or the entire build of this bike - a 1" post usually equals gaspipe. 26.6, however, would make more sense - it would be
metric 531 Professional, popular with the French builders.

I'm still not convinced it's French, or if it is, that it hasn't been damaged. Have a shop pull the crankset and BB out. I'm still worried that someone might have shoved and cross-threaded an English cartridge BB into the right side. Mind you, Velo Orange was the first of anyone to produce an exclusively French-threaded, cartridge BB earlier last year, with exception to Phil Wood and his ring-adjustable BB's. I doubt the latter, but if it is so, you'd be best off getting the proper left cup:
