I agree on the whole changing of the chain diameter being a negative thing so my primary tri bike and road bikes both are Sram AXS with Shimano compatible cranks and cassettes. I’m also anti 10 tooth on the cassette too and don’t like the Sram cassette ratios. Put one of these bad boys on and both bikes run sweet having the best of all worlds…
