Wilier Triestina launches New Filante SLR ID2
In the theatre of speed, there is only you.
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.
A new aero benchmark on the market
Rigorous testing in the Silverstone wind tunnel pushed an ambitious project beyond all expectations. The verdict was extraordinary: A 13.6% reduction in drag, exceeding the 12% estimated by CFD simulations. In the complete bike-rider system - always central to Wilier - we recorded a 4.5% improvement in aerodynamic resistance.


The comparison with the Filante SLR ID1 highlights tangible and significant advantages: maintaining the same speed of 40 km/h, a substantial 14.15 Watts of power is saved. Even more impressive are the data over distance: by applying the same power of 290 W over a 70 km route, a gain of 1 minute and 45 seconds is achieved, a margin that truly makes a difference in a competitive environment.


The decisive test came in direct comparison with the five competitor top-of-the-range World Tour bikes: an average aerodynamic resistance coefficient 2.42% better. At the speeds of modern cycling, this difference means seconds gained and concrete competitive advantages in the race.
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.
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.
The Colour of Speed
Once again, at Wilier Triestina, colour is not just about looks: it is identity and emotion. Each shade stems from research capable of transforming light into matter and matter into sensation. The surfaces narrate movement and reflect the passion that animates every one of our bicycles: colour becomes the language of speed.
We have chosen colours capable of enhancing the silhouettes of the Filante SLR ID2. In the sunlight, every shade reveals its strength, expressing the essence of speed: an energy that flows over the shapes and transforms performance into emotion.
On the upper part of the frame, the colour makes way for exposed carbon, allowing the heart of the frame to emerge in its essence, amplifying the perception of dynamism and tracing a visual dialogue between the seatpost and handlebar: a gesture of absolute formal coherence.
The Filante SLR ID2 will be available at launch in the following colours:
PURE WHITE
An absolute white, pure and brilliant like snow in the sun. This colour reflects every ray of light, transforming the surface into a living mirror that appears to move with you. Bright, clean, dazzling: it is the sensation of riding inside the light itself, with a purity that knows no shadows.
SOLAR BRONZE
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.
AURORA BLUE
A regal blue that embraces red and gold in a single surface that captures the light of dawn. It is a colour that lives and breathes with the light: now it shows the majesty of midnight blue, now the ardour of morning red, now the golden splendour of the rising sun. Every reflection changes like dawn streaking across the sky, powerful and harmonious. Aurora Blue is part of the Wilier Premium Paint programme.
LUNAR GREY
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.
ECLIPSE BLACK
Deep and glossy, like polished obsidian. Eclipse Black holds onto the light and releases it in subtle reflections, much like an eclipse that both shows and conceals at the same time. It is a colour that transmits absolute elegance, silent power, and a touch of mystery, amplifying everything around it.
