The Wilier Filante SLR ID2 represents the second-generation evolution of Wilier’s flagship aero race platform, developed in close collaboration with the Groupama–FDJ WorldTour Team.
Rather than chasing wind-tunnel numbers alone, the ID2 focuses on real-world performance by optimizing the entire bike-and-rider system. Frame profiles, rider positioning, and integrated components work together to significantly reduce aerodynamic drag while improving stiffness, stability, and long-distance efficiency.
At a constant output of 290 watts, the Filante SLR ID2 saves 1 minute and 45 seconds over 70 km compared to the previous generation—performance gains that translate directly into competitive advantage on the road.
