So we all know how much wheelsets weigh. Manufacturers prominently advertise weights. (even if they exaggerate) If you're looking for a set of climbing wheels, it's easy to find how some given wheelsets compare in weight.

What about aero drag? This data seems much harder to come by. The marketing hype would have us believe that rim shape can make a significant difference on overall drag. But where are the numbers? How does anyone pick wheels for a TT bike? Is there an an Aeroweenies counterpart to the Weightweenies website?
