The benchmark in the aero bike segment The natural evolution of our high-end aerodynamic bike used by professionals. Filante SLR is an extremely lightweight aerodynamic bicycle with a significantly improved stiffness-to-weight ratio. The bike is used by the athletes of the Groupama - FDJ Cycling Team. Filante SLR was designed to maximise aerodynamic performance in real environmental conditions. The design was based on data recorded in the wind tunnel (where the wind is very clean for homogeneous empirical results) while also taking the real world into account. In this way, we not only evaluate typical wind tunnel data (yaw angles from -20° to + 20°), but also consider environmental turbulence that impacts the bike for many different reasons. That’s why we redesigned the profiles, starting with the standard NACA airfoils/ KAMM tail that no longer have sharp edges on the back. The softened angles improve performance even when the airflow is disturbed. The inside of the front fork has been widened by 7 mm, making it 13.6% wider than the Cento10PRO. In doing so, we moved the fork blades away from the wheel, reducing turbulence and improving aerodynamics.
