Wilier Filante SLR ID2: The Ultimate Evolution of WorldTour Aerodynamics The Wilier Filante SLR ID2 represents the pinnacle of aerodynamic racing bikes developed by Wilier Triestina. Engineered in close, direct collaboration with the riders and performance staff of the Groupama – FDJ Cycling Team, every section of this frameset places the rider at the absolute center of the design. Speed, raw innovation, and Italian craftsmanship merge into a chassis engineered to deliver maximum efficiency, handling confidence, and stability under the most demanding race conditions.

Proven Wind-Tunnel Supremacy: Measurable Real-World Gains Rigorous aerodynamic testing inside the Silverstone wind tunnel pushed this project past engineering expectations. The results show a striking 13.6% reduction in aerodynamic drag compared to previous designs. When looking at the complete bike-and-rider system, total aerodynamic resistance is improved by 4.5%. For a cyclist riding at 40 km/h, the Filante SLR ID2 saves an impressive 14.15 watts. Over a 70 km course completed at a steady 290W, this translates directly to a time saving of 1 minute and 45 seconds. Head-to-head benchmarking against the top five WorldTour bikes reveals an average aero coefficient improvement of 2.42%.

Integrated Innovation: Aerokit System and F-Bar ID2 Cockpit The down tube area has been meticulously sculpted to minimize wind resistance caused by water bottles. The specialized Aerokit System developed with Elite acts like an aerodynamic spoiler, stabilizing airflow around the frame and reducing cage drag by over two-thirds compared to standard layouts while providing a 1100 ml fluid capacity. Up front, the F-Bar ID2 integrated carbon cockpit features Optimized Ergonomic Flare (O.E.F.), introducing a 3 cm orthogonal flare between the hoods and the drops. This layout preserves perfect lever ergonomics while encouraging a natural, fast, and comfortable riding posture. Additionally, the handlebar clamping hardware is completely concealed from the wind, protecting it from sweat and grime while remaining fully UCI compliant. You can optimize your interface by looking through our Road Handlebars and Accessories.

Advanced Technical Features & Frame Integration:

• High-Efficiency Aero Fork: Features external NACA airfoils paired with a flat internal profile to smooth airflow around the spinning wheel. A thin aerodynamic fin on the left leg shields the disc brake caliper, utilizing technology originally developed for the Supersonica SLR.

• Low Center of Gravity: The Shimano Di2 battery has been strategically relocated to the bottom bracket area. This lowers the bike's overall center of mass, enhancing high-speed stability and offering cleaner access.

• Increased Tyre Clearance: The fully updated rear triangle provides increased clearance for tyres up to 34 mm, drastically improving vibration damping and cornering traction on modern road surfaces.

• UDH Dropouts & 1x Options: Stays are angled inward by 2.5° for improved heel clearance, paired with a universal UDH derailleur hanger and a removable front mech hanger that allows for sleek 1x setups with up to a 56T chainring.

Premium Materials, AccuFit System, and Artistic Finishes Constructed using an elite blend of Toray premium carbon fibers (T800, T1100, and M46JB), the Filante SLR ID2 achieves a benchmark frame weight of just 870 grams, allowing a complete Shimano Dura-Ace Di2 build to weigh in at approximately 7.1 kg. Precision fitting is guaranteed by the advanced AccuFit framework: with six frame sizes, seven spacer options, five stem lengths, and two seatpost offsets, riders can dial in 420 unique positional combinations—each differing by a mere 2 mm—for a true custom fit.

This high-performance platform is finished with exquisite Italian paint schemes designed to highlight its sleek aero lines: choose between the luminous Pure White, metallic Solar Bronze, shifting Aurora Blue (premium paint), subtle Lunar Grey, or deep Eclipse Black.
