Prototyping with Precision: Équipe cycliste Groupama-FDJ United Refines Wheel Designs
Ahead of the 2026 season, Équipe cycliste Groupama-FDJ United ran a simulation study in partnership with high-end cycling component manufacturer Miche to develop and improve the aerodynamic performance of their wheel rim and hub designs. These components play a critical role in minimizing drag, directly impacting speed and efficiency. The team, closely collaborating with Victor Simonin, R&D Engineer and CFD expert at Équipe cycliste Groupama-FDJ United, targeted improvements across a range of side-to-side — or yaw — angles to account for the varying wind directions during real-world cycling scenarios. Using detailed CFD simulations created with Ansys Discovery structural simulation software, and Ansys Fluent fluid simulation software, they optimized the airflow interaction between the tire and rim while addressing the overall aerodynamics of the wheel. By evaluating multiple prototypes, they identified the optimal configuration that not only decreased drag but also maintained consistent performance under different conditions. Their new wheel configuration gets its inaugural ride in the 8-stage Paris-Nice race from March 8-15, 2026.
