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

Developed hand-in-hand with the Groupama - FDJ United 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.

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.

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 United 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.

The seatpost that combines efficiency and light weight
With the experience gained in the development of the Supersonica SLR, we already had the right formula in our labs: a balance between aesthetics, light weight, and comfort.

The new seatpost for the Filante SLR ID2 originates from this recipe, featuring a slender and sharp profile that optimises aerodynamic penetration without compromising stiffness and while guaranteeing good vertical vibration absorption.

It is available as standard with 0 offset or – upon request – with 15 mm setback.

Rear triangle: aesthetic continuity, technical evolution
We chose to preserve the family feel of the previous Filante, maintaining wide rear stays that join the seat tube with a broken line, which gives the frame a determined character when viewed from behind.

To a superficial eye, they might look similar to the ID1 version, but in actual fact, they have been redesigned in every detail. Analyses of the dynamic interactions between the stays and leg movement during pedalling guided us towards a counter-intuitive solution: inclining the stays inward by 2.5°.

The rear triangle has been slightly lengthened: a choice that allows for better integration of the new transmission groupsets with the UDH dropout, increases tyre clearance (up to 34 mm), and improves the overall stability of the bicycle.

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.

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.

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.

Geometries and fitting
Direct collaboration with the Groupama - FDJ United Cycling Team led us to refine every minute detail in terms of frame geometries. The goal: to have a virtually bespoke fitting system.

Thanks to the AccuFit system, every size maintains the same geometric consistency and fitting precision, delivering a balanced, natural, and high-performance riding experience, whatever your height or pedalling style.

The Filante SLR ID2 is conceived like a tailored suit for you: with 6 frame sizes, 7 handlebar spacer combinations, 5 stem sizes, and 2 seatpost versions, 420 fitting configurations are possible, each differing from the next by a mere 2 millimetres. This precision allows for a customised saddle position, like a high-end tailoring garment.
