Commenting on that article... rigid is not always better. Usually you want frames rigid in torsion, but some flex in longitudinal bending for a decent ride. But also, the head guy at Bicycle Quarterly has opined that he prefers a frame matched to the rider weight and style, not completely rigid, but having just the right spring to it in pedaling. I have not experienced what he is talking about, but he's a hard-core biker, and samples among the best bikes on the market, so I don't discount what he says.
