Switching to road tires/wheels on my gravel bike

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

However, if you want to avoid “gotchas”, match the hubs between the two. That way brake rotors will be identically spaced, as will the cassette.

Nothing like dropping in a spare wheelset and finding out the rotors are about 1-2mm different spacing, and now graze your brake pads.
As an alternative, you can just add shims to the rotors on the wheelset that is mis-aligned.

Yup, but you can only shim out, so you shim whichever rotor is further in to the position of the rotor that's further out.

Darn it! If only there was a way to change the gear ratios on a bike while riding...
