you'll either have to turn every rotor to clear the hub when you need to replace rotors, or turn the hub and replace it.

or, turn the hub, and when the bearings go out, replace just the bearings. it is easy to swap the whole hub since that's how it was designed, and entire hubs are available for sale, but you can also get just the bearings and replace them, keeping your hub.

I'm going to try to do mine on the "cheap" and with the hub mounted, use an angle grinder to remove metal while turning the hub as the grinder makes contact. might take me an hour or so per hub, but it's "free"

unless I find someone who can turn the hubs down for cheap, like $40 each. then it might just be easier to have them do it.
