Notes from MyBikeThing The Italian thread version is the one you need for Colnago, De Rosa, Pinarello, and other classic Italian frames. Chorus BBs run three sealed cartridge bearings (two drive-side, one non-drive) and are built to Campagnolo’s exacting standards. This is the correct spec for Chorus and Record 9/10-speed double cranks.
Workshop Wisdom Italian thread drive-side cups are right-hand thread — unlike English/BSA which is left-hand on the drive side. This means the Italian cup can back itself out under pedaling load. Use a light thread-locking compound on the drive cup at installation. Don’t skip this step.
