Bottom Bracket sizing help - Medici Pro Strada
I just got this 70s Medici frame on ebay and started collecting components to mount on it. First up, bottom bracket and crankarms.

I found an english thread Campagnolo Daytona BB, thinking it would be a standard size. Lo and behold it's about a mm or two too small in diameter. I've not been able to find much info online about the different BB sizing. Can anyone provide any insight? Greatly appreciated.
Here's the side of the BB:

Yep, it's Italian.... Italian measures 36mm which is right about 1.5mm larger than english....

well since that frame is no good since it does not have a universal fit BB shell. I'll take it off your hands LOL

Italian and English are not interchangeable. Medici used Italian bottom brackets on most (if not all) frames even into the late 80's.
