I used to have a Stages Rival PM (GXP) so ran sram chainsets on several bikes which were otherwise campag. Many thousands of miles clocked up. Never skipped a beat. As long as the chainrings and chain were the same number of speeds, ie 10 or 11, as the rest of the group then you're all good.
This is a 10 speed chainset with 11 speed Chorus. Never been a problem for me. The inside dimensions of 10 & 11 speed chains are the same so up front it rarely matters.
Yeah TBH I've run 10 Speed sram rings on 11 speed campag too without issue but thought I might have just got lucky there hence suggesting to keep it all matching. Just in case.
