KEY FEATURES

Why we like the Wilier Filante SLR ID2 Ultegra Di2
Scientifically Proven Speed
The Filante SLR ID2 saves a substantial 14.15 Watts at 40 km/h compared to its predecessor. This translates to a real-world gain of 1 minute and 45 seconds over a 70 km route, providing a decisive advantage in breakaway scenarios or solo efforts.
Ergonomic Control
The new F-Bar ID2 cockpit uses an orthogonal flare that keeps brake hoods in a natural orientation while widening the drops. This allows you to maintain a tucked, aerodynamic position for longer periods without sacrificing comfort or lever accessibility.
Maintenance-First Engineering
Unlike many aero bikes that hide batteries in difficult locations, Wilier positioned the Di2 battery in the bottom bracket box. This allows for quick inspections or replacements without the need to remove the seatpost or disturb your precise saddle height.
