Wilier Filante SLR ID2 PM SRAM RED Power Meter Carbon Race Bike Blue 2026

Season:2026

Brand:Wilier

The fastest version of yourself

The Filante SLR ID2 represents the ultimate evolution of Wilier’s aerodynamic racing bikes.

Developed hand-in-hand with the Groupama - FDJ Cycling Team, every detail is engineered around you and tells the story of how we experience speed.

Lightweight, responsive, and extremely aerodynamic, the Filante SLR ID2 redefines performance standards by putting you at the centre of every design choice. Aerodynamics is not an end in itself, but serves the rider, delivering maximum efficiency, comfort, and control in every condition.

Speed, innovation, and Italian tradition come together in a bike designed to enhance your riding experience - the fastest in the WorldTour landscape.

Integrated innovation: the Aerokit system

The down tube, which has always been one of the most complex areas from a design perspective, was developed with a precise goal: to have the minimum aerodynamic drag and to reduce the exposure of the water bottles to the air as much as possible.

The Aerokit system was specifically designed with this intention by our Innovation Lab together with Elite Cycling, a global leader in the design and production of hydration systems for cycling. This partnership has resulted in a kit that combines functionality and performance: 1100 ml of total capacity, optimally distributed and with a minimal aerodynamic impact.

From a technical perspective, the Aerokit functions as a veritable spoiler, capable of keeping the air more stable and less turbulent around the frame. Compared to traditional systems, aerodynamic drag is reduced by over two-thirds.

The Aerokit is also compatible with traditional round water bottles: 550ml on the down tube and up to 750ml on the seat tube.

The Filante SLR ID2 frame is designed to meet the different needs of cyclists by allowing for the installation of traditional bottle cages.

F-Bar ID2: aerodynamic cockpit for superior control and comfort

The new F-Bar ID2 is an aerodynamic cockpit developed around the needs of the modern cyclist, thanks to the joint efforts of engineers and the athletes of the Groupama – FDJ Cycling Team.

Every detail is designed to offer you maximum efficiency and control in all riding conditions. The O.E.F. (Optimized Ergonomic Flare) design introduces an orthogonal flare of 3 cm between the high and low grip (available in 35/38 cm, 37/40 cm, and 39/42 cm), which, unlike other handlebars with differentiated widths, keeps the ergonomics of the controls unchanged, guaranteeing you a natural, comfortable, and tucked position to improve aerodynamic performance further.

For the first time on a Wilier product, the handlebar clamping hardware is completely hidden, benefiting aesthetics, protection from dirt and sweat, and aerodynamic performance - all while fully complying with the latest UCI regulations.

Fork: true aerodynamic efficiency is in the details

For the design of the fork, we analysed numerous NACA airfoils - aerodynamic shapes derived from aeronautics and mathematically defined to ensure maximum efficiency in the airflow. Every airfoil was tested in combination with the wheel and tyre through CFD simulations, considering different wind incidence angles to reproduce real-world usage conditions.

The result is a fork whose legs combine an external NACA airfoil with a flat inner profile.

The fork crown cone is even more pronounced than on the Filante SLR, guaranteeing greater torsional stiffness combined with superior stress resistance.

The left fork leg integrates a thin aerodynamic fin that skims the disc and envelops the brake caliper: a partial fairing already successfully experimented with on the Supersonica SLR, now further refined.

Finally, the thru axle clamping bushing has been completely encased into the right fork leg: a first for Wilier products, which combines aesthetic elegance, clean-cut silhouettes, and a tangible benefit in terms of aerodynamics.

Tyre clearance and front chainring

The Filante SLR ID2 has been designed to offer you the perfect balance between aerodynamics and versatility. A tyre clearance of up to 34 mm allows you to choose the perfect tyre to tackle a wide variety of surfaces with confidence, while simultaneously guaranteeing maximum aerodynamic efficiency.

Thanks to the removable derailleur support, the drivetrain can also be configured as a 1x setup, accommodating chainrings with up to 55 teeth. This solution enhances the clean-cut aesthetics, reduces weight, and boosts performance in the most ‘racing’ configurations.

Weight and materials: the essence of speed is in balance

For an aero frame, the starting point is always the pursuit of balance between aerodynamics, stiffness, and responsiveness. It is not about chasing extreme light weight, but about achieving maximum efficiency at high speeds, guaranteeing a precise and stable response in every riding condition, while still allowing for builds slightly above the UCI limits.

To achieve this goal, the choice of materials is crucial. For the Filante SLR ID2, we have also adopted the highest quality composites, the result of a collaboration with Toray, a world leader in carbon fibre production.

For the lamination of the monocoque, three types of fibres are used – T800, T1100, and M46JB – selected and mixed better to combine responsiveness, stiffness, and light weight, resulting in an overall weight, in the Dura-Ace Di2 specification, of 7.1 kg.
