Or does XDR fit in a narrower dropout spacing than other typical road hubs with disc brakes?
Though maybe a moot point since you've got a hub ordered.
XDR is SRAM 12-speed Road with a XDR freehub. XD is Mountain. Shimano 12-speed is Microspline, I believe. I don't think Shimano really sells aftermarket high-end hubs maybe outside of Shimano setups for Shimano group sets. I wanted totally silent so went with Onyx.
