"Wilier Triestina has always treated speed as something poetic - not just a measurement, but a feeling. With the new Filante SLR ID2, that idea gets a complete redesign. Developed alongside the Groupama-FDJ WorldTour Team, Wilier's latest flagship aero bike isn't just another incremental update. The Filante SLR ID2 sets a New Standard for Speed for Wilier. A complete rethink of what "aero efficiency" means when the rider is part of the equation."
"At a glance, the Filante SLR ID2 doesn't stray far from the Italian brand's signature aesthetic. That balanced mix of sculpture and science, but underneath the surface sits a ground-up aerodynamic overhaul. The results speak clearly: a 13.6% reduction in drag over the outgoing model, verified at the Silverstone Sports Engineering Hub wind tunnel. That's beyond the brand's own CFD predictions and translates to 14.15 watts saved at 40 km/h."
"Every design choice - from tube shapes to bottle integration - was made with the rider in mind. The goal wasn't just raw aerodynamics, but the balance of efficiency, comfort, and control across real-world conditions. The fork, for example, uses NACA-derived airfoil profiles paired with a flat inner leg surface to stabilize airflow and reduce turbulence near the wheel and brake caliper. A subtle aero fin hides the front disc mount. This is a feature first tested on Wilier's Supersonica SLR TT bike."
Wilier Triestina's Filante SLR ID2 redefines aerodynamic performance through a ground-up redesign developed with the Groupama-FDJ WorldTeam. Wind-tunnel testing at Silverstone verified a 13.6% drag reduction versus the previous model, equating to 14.15 watts saved at 40 km/h and roughly 1 minute 45 seconds over 70 km at 290 watts. Design choices target rider-influenced aero efficiency while balancing comfort and control. The fork uses NACA-derived airfoil profiles with a flat inner leg and a subtle aero fin to stabilize flow and conceal the front disc mount. Rear seatstay angles and increased 34 mm tyre clearance optimize wake management and real-world compliance.
