I think the road bike can handle 28mm (but I haven't tried it yet) and the gravel bike can handle anything down to 28mm. Although it may sound odd to be considering racing the gravel bike, it would provide a smoother ride and, over the course of a 250+ mile racing weekend, it could take me to the end of the day with more energy left in the tank. It's really just a titanium road bike with a longer wheelbase and more tire clearance. Almost certainly, the road bike gets the call, though.
