from what i've heard yes, next year. all i've heard is that it will allow mix and match, but not exactly sure what that will entail. i didn't specifically hear it is 12s, that is just my guess, kinda doubt it will be 13s. no udh required.
I guess it will be SRAM AXS like if they ever want to compete in the MTB and gravel segment. They put all their chips in powering e-bikes I guess and that market is really competitive RN
Is there a plan for shimano 12 speed 1x Di2? #buyer
