No shit?
I've been scouring the internets for wheelsets, hubs, adapters, etc..etc. Shimanos will work? Much easier to locate here in the US.
I was told to use a Campy Chorus crankset. Also chain needs to be for the Chorus 12 speed.
Well, that’s what the dealer and Campagnolo will tell you. But no. It all works just fine. Campy cranksets aren’t the lightest (for a carbon crank) but they definitely are the prettiest, though. And their chains are honestly just really really good and last forever. I got a Chorus 12s chain with 10k km on it and it doesn’t really show much sign of wear. So I can really recommend them.
With 10sp and less, you needed Campy specific cassettes or a pull ratio converter like the stuff from Jtek to make it work. But with more and more gears, there’s just no room to make a significant enough difference in gear spacing. So 11sp and 12sp is cross compatible. I even ran an 11sp Chorus groupset with both an 11sp Campy cassette and with Shimano cassettes on another wheelset. Absolutely no difference whatsoever.
