New SRAM Eagle Transmission - 2023

I have not personally messed with it, but my understanding is that you can use an adapter to a regular RD hanger on a MTB, but it’s technically out of spec for Shimano on road/gravel frames. Not sure if that means it simply won’t work or just not optimal, but there is much discussion on this point in the gravel world. If people want transmission, they will be drawn to bikes that support UDH, but the bike companies don’t want to design a frame that can’t support both shimano and SRAM (and both 1x and 2x). for bikes that were already 1x only, those will be the most likely to go UDH. There is talk of having 2 frame options, but that creates a lot of complexity that they’d rather avoid.
