gearing with say 39/24 and a 165 crank 700c wheel. Thats around 31 pounds of go force for every 100 pounds applied to the pedals. So for every 100 pounds applied while spinning the tire needs 31 pounds of traction plus some traction left for cornering. And you can't apply even 1,000 pounds(one leg) to the pedal while spinning, physics and biomechanics won't allow it. in fact at a set weight, speed, gear and grade climb, everyone exerts the same pedal force.

Slow twitch, fast twitch, or nervous twitch?
