The biggest gear allowed is for example 52-14, but as there are still no shimano 12 speed cassettes with the smallest cog being 14, could I use a campy cassette instead (they offer such a size) or would it not work. I could probably use a smaller chainring, but it would have to be really small for the rollout to be inside the regulation with the smallest cog on the cassete being 11 and I don’t think the front deralieur would work with such a small chainring (I think it would have to be a 41).

Hope someone can answer my question and thank you in advance.
