The frame provides the core aero advantage, but wheels are the second-largest source of aerodynamic drag on a bike. Deep-section wheels (50–60 mm front, 60–80 mm rear) complement the aero frame and can save an additional 5–10 watts at 40 km/h compared to shallow alloy wheels. Many complete aero bikes come with appropriate wheels, but if yours has shallow wheels, upgrading to deep-section wheels is one of the most cost-effective speed improvements available.
