Well, I presented it as a hypothesis which I can’t prove. In the old bicycling science pages there was an account of a finite element model that supports it, but that isn’t enough, either. As far as a psychological deception, I have one example of the bikes Heine card were good at planing, and I do not experience nirvana, as my Post explained.
But I have had an experience similar to that of Phamilton while riding my 1980Masi, and to a lesser degree on my ELOS Mondonico.
