The Wilier Filante SLR represents the pinnacle of Wilier Triestina’s aerodynamic road bike development. Designed as the natural evolution of the Filante platform, the SLR version delivers a class-leading stiffness-to-weight ratio, exceptional aerodynamic efficiency, and race-level responsiveness.
Developed using extensive wind-tunnel testing and real-world turbulence analysis, the Filante SLR refines traditional aero profiles with softened trailing edges to maintain performance even in disturbed airflow. The result is a bike that excels not only in controlled lab conditions, but in fast, chaotic racing environments.
With a frame weight of just 870 g, integrated cabling, and Shimano Ultegra Di2 electronic shifting, the Filante SLR is engineered for riders who demand uncompromising performance at the highest level.
