Wilier Filante SL | World-Tour Aerodynamics & Precision Shifting

The Wilier Filante SL is engineered for speed, inheriting the race-proven aerodynamic profiles of the top-tier SLR model used by professional teams. Constructed with NHU-MOD Carbon Monocoque and reinforced with high-impact strength resins, the Filante SL delivers an exceptional stiffness-to-weight ratio. This build is equipped with the industry-leading Shimano Ultegra Di2 R8170 12-speed wireless groupset, offering elite electronic performance and the practical adjustability of the Wilier Barra S and Stemma S cockpit system.

Performance & Aero Highlights
