that slowtwitch article ignores the fact that the rim weight also contributes to the total mass being accelerated (though it will be a small percentage of the total system mass) and assumes that wheel/rim shape can make an appreciable dent in the amount of power required to overcome air resistance. It could be argued that 99% (or whatever it is, certainly a large percentage) of the air resistance is due to the frontal area of the rider, and if so we're back to saying wheel weight and wheel "aero-ness" are both not very significant...
hahaha
