Sorry for the dumb question.... I'm upgrading my 05 Pinarello Marvel from Centaur to Chorus. Is the bottom bracket English or Italian thread? Everyone I've talked to says English, but since it's an Italian bike I question it.
Thanks in advance!

When you look at outside edge of the driveside BB cup (more easily done with the crank removed) you will be able to read the thead size engraved/stamped on the surface ... it will either be 36x24 (Italian) or 1.37x24 (English).
BTW. If the cups are Italian, both cup have right hand threads; and, if the cups are English, then the driveside cup has a left hand thread.
