Probably worth noting the following:
KMC chain etc, Shimano / SRAM cassette used with a Campag system will void warranty (just as it would working the other way around).
What Zinn et al forget is that there are actually spacing differences between Campag and Shimano / SRAM 11s cassettes - or maybe they just don’t know. 11-ups are slightly different 1st three sprocket spacing to 12-up, different again to 13-up where this is not the case with Shimano or SRAM so by definition, Shimano and SRAM will not shift as intended on a Campag system.
KMC chains are a hybrid width, flexibility and plate profile to try and be all things to Shimano, SRAM, Campag and now random 1x thick-thin chainring makers, so expect degraded front shift performance and noise.
All of this stuff depends entirely on your definition of “work” but in our workshops and out on the road (we look after several prestigious sportifs and Gran Fondos) I see plenty of systems that the riders regard as satisfactory, until they are set up properly, at which point the riders usually comment that their bike has never been so quiet / smooth / slick shifting etc …
On a smart trainer I know shifting considerations are perhaps not so important but swapping chains around may also affect you on the road and it’s irritating to see innaccurate info with (in this case) regard to chain & cassette compatibility published for all to see, when the impact on wider rider experience and on the brand reputaions of the manufacturers can be detrimental.
