On a bike with a freewheel though, you could probably manage short bursts of a super-fast cadence to just *barely* maintain enough speed to stay in the draft... -Trevor |

That's what gearing is for. There is a difference between the force you put down on your pedals and the force of the air pushing against you. You've confused the two. One you would use gearing to overcome, the other.. other than getting more aerodynamic, I'm not sure if there are any other ways to overcome wind resistance. |

Of course, the drag force is "two thirds" of the power, so it's important for sure, but it's not really what we fight against when we pedal. Our effort pedalling is the power required, but the force we're pushing down the pedals with depends mostly on gearing, and is limited at the lower end by the cadence we're comfortable with. |
