"The Aerodynamics of Drafting: Comparing Aero vs. Non-Aero Cyclists"
A recent discussion on the Performance Process podcast with Alex Dowsett raised the question of whether it's easier to draft behind an aerodynamically optimized cyclist or one with less aerodynamic efficiency. Surprising results from CFD simulations by Nablaflow's CEO Luca Oggiano revealed that it is marginally easier to draft behind a more aerodynamic rider, contrary to the common assumption that a less aerodynamic rider would provide a better draft. The simulations showed that a following rider experiences less drag behind an aerodynamically optimized lead rider, saving more watts compared to drafting behind a less aerodynamic lead rider. The study also found that the aerodynamics of the drafting rider can affect the lead rider's required effort, with different configurations leading to varying watt savings. The findings highlight the complex nature of aerodynamics in cycling and suggest that maintaining a closer distance to the rider in front remains the most effective way to maximize drafting benefits.
