I think the problem with heavy bikes isn't only the weight itself. It's the fact that heavy bikes typically have much cheaper components / manufacturing overall. Consider that adding 5 pounds to stationary components, like the frame, is adding < 5% to the amount of work being done by the rider, depending on the rider's weight. I took his comments on bike weight as him saying that it isn't really worth worrying about an extra pound or two.
