I’m trying to find the ride groupset and shifters to go along with this campagnolo cassette, can anyone help me figure that out?

It’s beautifil. It looks like a shell.

Any Campagnolo group set from the same line and era would work but there are some minor compatibilities within that family… so you generally want a full Centaur group or a full Athena group (or Record/Chorus, or Potenza). What you can mixmatch there requires a much larger breakdown. There’s also pre-2015 Campagnol vs 2015+. The cassette spacing never changed, but the shifters and derailleurs typically need to match.

As others have said, you can get Shimano 11 or SRAM 11 to work acceptably well. When Shimano 11 first came on the market, there weren’t enough hubs available that fit a Shimano road 11 cassette so it was a common hack to use Mavic or Campagnolo wheels with a Campagnol freehub and cassette during that period… to mostly good results.

There are some caveats with that Shimano/Campagnolo mismatch and it doesn’t work for everyone. The two cassettes are NOT identical despite what any one tells you, but they are generally close enough to work. It works best with your scenario, a Campagnolo cassette with the largest sprocket tooth being in the 20s still.
