I have disc brakes.

If I want a second wheel set so I can easily switch between road and gravel tires in 2 minutes rather than 20....is it simple to get a second set of wheels where the disc rotors line up to the calipers?

As in, will the rotor always be X distance from the center of the wheel hub? Or do I need wheels with the exact same hub to make sure both rotors are in the exact same place?

(See what happens when it rains for 5 straight days? I can't burn off my energy riding my bike so I burn it off coming up with creative ways to spend more money on the bike)
