Are they really? You're saying that a sub 1500g wheelset has only a marginal advantage over a 2000g wheelset in those respects?

And for the sake of argument, if those advantages (which I have personally found to be substantive) are excluded, what else is there? Subjective 'feel'?

Why would anyone ride lighter wheels then? The psychological satisfaction?

My curiosity is sincerely piqued. Have I been thinking about wheels all wrong?
