Yes, on flat and rolling terrain. At 40 km/h, an aero bike saves approximately 15–25 watts compared to a lightweight bike with round tubes. This advantage diminishes on steep climbs (above 6–8% gradient) where the 200–400 gram weight penalty becomes more significant. For most riders on mixed terrain, the aero advantage on flats outweighs the climbing penalty, making aero bikes faster overall on typical road courses.
