Speed, Efficiency, and Energy Use
Road bikes win air battles with narrow profiles and low, stable positions. Less frontal area means more speed for the same power. Mountain bikes keep you upright for control, which is fantastic on technical ground but turns your chest into a sail when headwinds roar.
Speed, Efficiency, and Energy Use
Knobby tires deform more and sap energy, while road slicks hum efficiently. Road cassettes keep cadence locked at high speeds; mountain gearing tackles brutal grades without stalling. Consider your average terrain and choose where you’d rather feel that burn—on climbs or on flats.
