I’ve gotten well over 2k miles without noticing any issues with the jockey wheels. I forgot to mention my brother did the same thing with his AXS and at the same time. No issues at all with shifting Between he two of us. Maybe when my cassette wears out, I’ll try Sram cassette.Great to know. But some of the comments state that the narrow wide of the jockey wheels in the derailer don’t play nice with the shimano 12 speed chain?
