If getting lighter wheels is the only way to easily lighten your bike by a pound or so then the battle of rotational weight and just weight is meaningless anyhow.
So what's the point? I tried to listen but the audio quality was poor and evidently neither interviewer or interviewee could talk in full sentences.
But did they ever talk about to bikes of the same overall weight and one with lighter rims? Seems to me that the bike with lighter rims will accelerate faster. And about the only time that is needed is in a sprint. So if they didn't look at the models for just a 200 meter sprint, then they were making a big deal about nothing.
