From a common sense perspective, I respectfully disagree. I looked into this just a little and saw reference to the statement being true with one
huge caveat: the rider has to maintain constant speed. Physiologically this is impossible. We generate two distinct power strokes during one revolution of the crank, and with the force of gravity working against us we end up with rhythmic acceleration pulses up the hill. Therefore, the steeper the hill the more impact wheel weight has (speaking of weight at the rim/tire, the worse possible place.
Extreme example: how'd you like to climb a hill with sand-filled tires?
Hmm a little more research found this...
