These top quality loose bearing bottom brackets from Campagnolo’s Chorus range were the last of their kind. They were replaced by sealed all in one units which were nice and smooth but you had to throw them away and get a new one when it went. Campagnolo had been making super quality, user-serviceable BBs for over 40 years when these were built and it shows, they are a great example of what the company could achieve.
This version is British thread, with a 111 mm ISO axle for the curved arm Chorus cranks, it is also compatible with a couple of other Campagnolo cranks from the era.
