Hello, I'm wondering if someone can help with a little question I have regarding bicycle wheel size and the work associated with keeping it moving. I'm trying to understand how changing the wheel size (effective circumfrance) from 26" to 29" may impact the ammont of effort required by a bicycle racer while on an incline. Assuming the wheel weight is constant and disregarding exterior forces other than gravity how might one go about comparing the two? What I mean is does the simple physics of size play a role in work? I assume it does because a large protion of a bicycle wheel's weight is in the rim and tire, which is near the outer edge of the wheel and should affect rotational inertia, right?
