Das Filante SLR ID2 ist die konsequente Weiterentwicklung der aerodynamischen Rennräder aus dem Hause Wilier.
In Zusammenarbeit mit dem Groupama-FDJ Cycling Team entwickelt, ist jedes Detail auf Sie abgestimmt und zeigt, wie wir Geschwindigkeit definieren.
Leicht, reaktionsschnell und extrem aerodynamisch setzt das Filante SLR ID2 neue Standards in puncto Performance und richtet jedes Detail im Design konsequent auf Sie aus. Aerodynamik ist kein Selbstzweck – sie sorgt dafür, dass der Fahrer unter allen Bedingungen maximale Effizienz, Komfort und Kontrolle erlebt.
Geschwindigkeit, Innovation und italienische Tradition vereinen sich in einem Rennrad, das Ihr Fahrerlebnis auf das nächste Level hebt – das schnellste Bike der WorldTour.
Integrierte Innovation: das Aerokit-System
Das Unterrohr – traditionell eine der komplexesten Zonen in der Planung – wurde gezielt so gestaltet, dass es den Luftwiderstand minimiert und die Wasserflaschen optimal in den Luftstrom integriert.
Das Aerokit-System wurde genau zu diesem Zweck im Wilier Innovation Lab entwickelt – in Zusammenarbeit mit Elite Cycling, einem weltweit führenden Hersteller von Trinksystemen für den Radsport. Das Ergebnis dieser Zusammenarbeit ist ein System, das Funktionalität und Performance vereint: 1100 ml Gesamtvolumen – optimal verteilt und mit minimalem Einfluss auf die Aerodynamik.
Technisch gesehen funktioniert das Aerokit wie ein Spoiler: Es lenkt den Luftstrom gezielt und minimiert Turbulenzen rund um den Rahmen. Im Vergleich zu herkömmlichen Lösungen reduziert das Aerokit den Luftwiderstand um über zwei Drittel.
Das Aerokit ist vollständig kompatibel mit Standard-Rundflaschen: von 550 ml am Unterrohr bis zu 750 ml am Sattelrohr.
Eine neue Aero-Benchmark auf dem Markt
Strenge Tests im Windkanal von Silverstone haben ein ehrgeiziges Projekt weit über alle Erwartungen hinaus vorangebracht.
Das Ergebnis war außergewöhnlich: 13,6 % weniger Luftwiderstand – deutlich mehr als die zuvor prognostizierten 12 % der CFD-Simulationen. Im perfekten Zusammenspiel von Fahrer und Rad – eine Verbindung, die bei Wilier seit jeher im Mittelpunkt steht – konnten wir eine Verbesserung des Luftwiderstands um 4,5 % erzielen.
Der Vergleich mit dem Filante SLR ID1 zeigt echt spürbare und wichtige Vorteile: Bei gleicher Geschwindigkeit von 40 km/h spart man ganze 14,15 Watt an Leistung. Noch beeindruckender ist der Leistungsgewinn auf Strecke: Bei konstanten 290 W über 70 km spart man 1 Minute und 45 Sekunden – ein Vorsprung, der im Wettkampf den Unterschied macht.
Der entscheidende Test: Direkter Vergleich mit den fünf Top-Konkurrenten der WorldTour – mit einem durchschnittlichen Luftwiderstandskoeffizienten von unter 2,42 %.
Im modernen Radsport entscheiden diese Bruchteile von Sekunden über den Sieg – ein klarer, greifbarer Vorteil im Rennen.
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.
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.
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.
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.
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.
Geometries and fitting
Direct collaboration with the Groupama - FDJ 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 garme
