If you can swing it, I'd use a 700C wheelset for that purpose...nothing wrong with 2 wheelsets set up with the appropriate tires ;-)
Yes, of course that is an option. And probably the best way to go if multiple wheelsets are an option.
But I was just wondering, should I just get just 1 wheelset for now, what might be available if I try to get away with just a 650B set ... for both road and for gravel.
My only concern with running a 650B wheelset with "smaller" tires (i.e. something in the 28-30mm range, measured) is the possible effects it could have on steering geometry. If the bike geometry is designed around 700C wheels with tires that size, then with 650B, it's going to have drastically reduced trail and might be a bit "skittish" on the road.
After all, the diameter of a 650B rim is actually closer to a 26" MTB rim than it is to a 700C rim (despite
the "27.5" common nomenclature for that size wheel) ;-)
