Wilier Triestina Filante SLR ID2 Eclipse Black

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.

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.

Firelight Red is born where air ignites: hot, vibrant, like the instant oxygen meets heat and light explodes.

It all starts with white - pure oxygen, the primal purity, the point where the reaction begins. Silver details enrich the livery: the spark before combustion. Then red blazes forth, incandescent and bold - a luminous signature racing through space and time.

In this chromatic reaction Admiral Blue emerges: a blue that doesn't cool but guides the flame, directing it toward its purest essence. It symbolises the bond with Groupama-FDJ Cycling Team, a visual identity uniting bike and rider in one seamless language.

Firelight Red is the official livery of Groupama-FDJ Cycling Team for the 2026 season.

Warm and enveloping, like golden sand shimmering at sunset. Solar Bronze captures the light and returns it in metallic reflections that change with every glance.

It is the colour of solar energy transformed into movement, a balance between ancient elegance and modern vitality.

A deep grey, inspired by the moon’s reflections on the water.

Like the tides that follow its call, this colour plays with light in a subtle but continuous way, shifting from the soft tones of purple to elegant silvery glints.

Striking the perfect balance between sobriety and movement.
