Integrated innovation: the Aerokit system
The down tube, always one of the most complex areas from a design point of view, has been developed with a precise goal: to have minimum aerodynamic resistance and reduce the exposure of the water bottles to the air as much as possible. 
 
The Aerokit system was designed precisely with this intent by our Innovation Lab together with Elite Cycling, a global point of reference in the design and production of hydration systems for cycling. From this collaboration was born a kit that combines functionality and performance: 1100 ml of total capacity, optimally distributed and with minimum aerodynamic impact.
 
From a technical point of view, the Aerokit works like a real wing, capable of keeping the air more stable and less disturbed around the frame. Compared to traditional systems, aerodynamic resistance is reduced by more than two-thirds.
 
The Aerokit is also compatible with traditional round water bottles: from 550ml on the down tube and up to 750ml on the seat tube.

A new aero benchmark on the market
Rigorous tests in the Silverstone wind tunnel have brought an ambitious project beyond all expectations.
 
The verdict was extraordinary: 13.6% reduction in drag, exceeding the 12% estimated by CFD simulations. In the complete bike plus rider system - always central for Wilier - we recorded a 4.5% improvement in aerodynamic resistance. 
 
The comparison with Filante SLR ID1 highlights tangible and significant advantages: maintaining the same speed of 40 km/h, you save 14.15 watts of power. Even more impressive is the data on distance: delivering the same power of 290 W over a 70 km course, you gain 1 minute and 45 seconds, a margin that makes the difference in a competitive environment.
 
The decisive test came in the direct comparison with the five top-of-the-range models from the World Tour competition: an average aerodynamic resistance coefficient 2.42% better. 
 
At the speeds of modern cycling, this difference means seconds gained and concrete 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 work of the engineers and athletes of the Groupama – FDJ Cycling Team.
 
Every detail is designed to offer you maximum efficiency and control in every riding condition. The O.E.F. (Optimized Ergonomic Flare) design introduces an orthogonal flare of 3 cm between the low grip and the high grip (available in 35/38 cm, 37/40cm and 39/42cm) which, unlike other handlebars with different widths, keeps the ergonomics of the controls unchanged, guaranteeing you a natural, comfortable and compact position, to further improve aerodynamic performance.
 
For the first time on a Wilier product, the handlebar mounting hardware is completely hidden, to the benefit of aesthetics, protection from dirt and sweat and aerodynamic performance — all in full compliance with the latest UCI regulations.

Fork: in the details the real aerodynamic efficiency
For the design of the fork we analyzed numerous NACA profiles, aerodynamic shapes derived from aeronautics and mathematically defined to guarantee maximum efficiency in the airflow. Each profile was tested in combination with the wheel and tire using CFD simulations, considering different wind angles of attack to reproduce real conditions of use.
 
The result is a fork with outer NACA profile tubes and a flat inner profile.
 
The fork steerer cone is even more pronounced compared to Filante SLR, and guarantees greater torsional rigidity combined with superior stress resistance.
 
The left tube integrates a thin aerodynamic fin that touches the disc and wraps around the brake caliper: a partial fairing already successfully tested on Supersonica SLR, now further refined.
 
Finally, the thru-axle locking bushing was completely incorporated into the right tube: an absolutely unprecedented solution for Wilier products, which combines aesthetic elegance, clean lines and a tangible benefit in terms of aerodynamics.

The seatpost that combines efficiency and lightness
With the experience gained in the development of the Supersonica SLR, we already had the right formula in our laboratories: balance between aesthetics, lightness and comfort. 
 
The new Filante SLR ID2 seatpost is born from this recipe, with a thin and sharp profile, which optimizes aerodynamic penetration without compromising rigidity and guaranteeing good vibration absorption on the vertical plane.
 
Available as standard at 0 offset or - on request - with 15 mm of setback.

Weight and materials: the essence of speed is in balance

For an aero frame, the starting point is always the search for balance between aerodynamics, rigidity and responsiveness. It is not about chasing extreme lightness, but about achieving maximum efficiency at high speeds, guaranteeing a precise and stable response in every riding condition, while still allowing for builds just above the UCI weight limits.

 

To achieve this goal, the choice of materials is decisive. Even for Filante SLR ID2 we adopted extremely high-quality composites, the result of the collaboration with Toray, a world leader in carbon fiber production.

 

For the monocoque lamination, three types of fibers are used – T800, T1100 and M46JB – selected and mixed together to best combine responsiveness, rigidity and lightness, for an overall weight, in the Dura Ace Di2 specification, of 7.1 Kg.
