Eric - I checked both tires' pressure, thinking maybe the problem was linked to them, but nada. I've had these tires at these pressures for a couple of thousand miles now, and know their feel pretty well; this was definitely something different. If it helps at all, I lowered the handlebars about a half inch the night before. I can't see where that would have an effect on the handling, but bike balance can be a touchy thing, and I suppose it's possible that the slight change in center of gravity or handling might have made a difference.
