Campy 11 vs 12 bottom brackets

[duff_duffy]

I have an 11 speed Super Record crankset on a bike now…going to swap a 12 speed Super Record groupset onto bike (and SR12 crankset). Will the current bottom bracket for the 11 speed work for both cranks? Sorry, I’m being lazy today and don’t feel like researching…

Follow-on question: I just got a bargain unit of exactly that ProTech BB with sleeve etc... Problem is I can't work out if it is or isn't compat with Ultra-T 11S Chorus crankset. This place says it is:

But the cups inside have a clearly beveled interior - unlike the other UT BBs I have stashed. Looks like it shouldn't fit. The reason i wanted it was I'm planning an EPS conversion and am missing that wire-routing sleeve.

Any knowledge would be appreciated.

12s/11s/10s Ultra-Torque Cranks use UT BBs

12s Super Record Wireless, and Ekar/Ekar GT use ProTech
