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.

Enhanced integration of the Shimano Di2 battery
With such a sleek design for the seatpost, the Shimano Di2 battery needed to be repositioned. Moving the battery to the bottom bracket box area gave us multiple, immediate, and tangible advantages:
Accessibility: the battery, enclosed in a resin casing and secured with two screws, can be checked or replaced in a matter of moments, without removing the seatpost or changing the saddle height.
Lower centre of gravity: the new position contributes to lowering the bike's centre of mass, in synergy with the lowered Aerokit. The result is a more stable, precise, and manageable bike when riding at high speeds.

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.

Tire clearance and front chainring
The Filante SLR ID2 has been designed to offer you the perfect balance between aerodynamics and versatility. A tire clearance of up to 34 mm allows you to choose the perfect tire 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.
The Filante SLR ID2 is available in the following 6 colours.
