So the hub has to be correct for your dropouts, but that does not mean you can’t use a hub that works with a disc, and still put rims on it with brake tracks for rim brakes.
in our example, our tandem has 135mm spacing, and has both mounts for rim and disc brakes. We have wheels built with 240 DT hubs, that can accommodate a disc, but are laced to rims with brake tracks for rim brakes.
So if you want to build a wheel for rim brakes, the issue for the hub is not whether it’s rim or disc; it’s whether it fits your dropouts.
And for many hubs today, including DT 240’s, they can fit different dropout spacing depending on what end caps you use.
So again, the issue is dropout spacing, not whether it’s rim or disc.
