I think hills are well covered - if you have to move the same amount of mass up either way, it doesn't much matter where said mass is on the bike. Accelerating

I think hills are well covered - if you have to move the same amount of mass up either way, it doesn't much matter where said mass is on the bike. Accelerating, as the article mentions, is the one place that their theory holds. My question was why that's considered more important than holding speed (which heavier wheels makes easier) or the extra bearing friction.
