I'm considering building up a bike with a Campagnolo 12 speed mechanical groupset with a Shimano cassette.

I've been using Campagnolo 11 speed with a KMC chain and non-campy cassettes without any problems for a long time. I would prefer to use non-campy cassettes again for the 12s setup, as Shimano 11 speed hubs are compatible with 12 speed cassettes, meaning I wouldn't have to replace them.

Does anyone have any experience running 12 speed Campagnolo with Shimano 12 speed cassettes?

  • I tried comparing cassette spacing between the Shimano 12-speed road cassettes and Campy 12-speed cassettes. I assumed (!) that Shimano and SRAM cassettes are interchangeable, and based on this website obike.dk/teknisk_info there is a difference between the SRAM and Campagnolo cassettes. But then I watched this video youtube.com/watch?v=ha3lalBRCHI where the conclusion is that even the SRAM-Shimano compatibility is questionable. This is a non-answer but what I've seen so far implies compatibility woes across all 3 manufacturers' lines.

  • @jayded-bee thanks for that video link. I'm not surprised the Sram cassette didn't work well with Di2, because of the 10T cog and electronic system. This isn't an issue for mechanical Campy/Shimano though, so I'm more hopeful it might work. But still good to know! Jun 27 at 16:16
  • Curious if you got an answer to this? I’m considering the same thing. I’m assuming it would work since 11 speed shimano cassette and chain will work with 11 speed Campagnolo. I am assuming that because the space is the same. Aug 1 at 1:38

1 Answer 1


The new shimano 12 speed system compatibilty rule is:

  1. 12 speed cassete can be used on 11 speed hub
  2. 12 speed freehub only accept 12 speed cassette, incompatible with 11 speed cassettes.

So you can put the 12 speed cassette on your 11 speed hub (freehub).

    This answer does not address the question - the question is not about compatibility between Shimano cassettes and Shimano hubs, it is about compatibility between Shimano cassettes and Campagnolo derailleurs. Jun 27 at 10:27
