Nieuwsgierig als ik ben ben ik meteen gaan googlen, en toen vond ik volgende uitspraak op De Varna site:
"
- Reduction in aerodynamic drag. The wheels of a cycle are an important place to reduce aerodynamic drag, as the top of any rolling wheel is moving into the wind at twice the speed of the rider/cycle (aerodynamic drag increases exponentially with speed). Smaller wheels present less frontal and surface area to the wind, and are proven to to have less aerodynamic drag than larger wheels. Even at slow speeds, the reduction of aerodynamic drag when using a 20 inch wheel is much greater than any increase in rolling resistance (which increases linearly with speed) over use of a larger wheel.
