I guess more and more people bought into that hype. The aero claim that Flo and Zipp have is around the toroidal shape of the rims, not just simply from the fact that the rims are wide.
The typical benefit of a wider profile is a ride that is more like a tubular setups, but the thing i noticed most was better handling, since the 23mm tire shape has less of a bulb-like profile when it sits on a 23mm brake track.
