That does make sense. But What got me was when we were going down a street slightly downhill and a guy was next to me. He would pedal couple times and get down faster than my constant pedaling. So my only deduction was that he has to have a better build of wheel. That would be the only thing, in my mind, that made sense. Besides this guy mentioned he did at least 5 to 9 miles a week before the ride and he was still up there. Of course gear rations is the obvious answer but I know have more stamina than that guy. =/ Maybe I should do an experiment and swap wheels with somebody and see how that feels.
