WILIER FILANTE SLR MOON GREY FRAMESET

The new master in the art of aero
The natural evolution of our high-end aerodynamic bike used by professionals.

Filante SLR is an extremely lightweight aerodynamic bicycle with a significantly improved stiffness-to-weight ratio. We used the same materials and technology as in the construction of the Wilier 0 SLR.

The result is a top-of-the-range, aerodynamic frame that complements our pure ascent bike used by the Astana Qazaqstan Team.

AERODYNAMIC
Filante SLR was designed to maximise aerodynamic performance in real environmental conditions. The design was based on data recorded in the wind tunnel (where the wind is very clean for homogeneous empirical results) while also taking the real world into account. In this way, we not only evaluate typical wind tunnel data (yaw angles from -20° to + 20°), but also consider environmental turbulence that impacts the bike for many different reasons.

That’s why we redesigned the profiles, starting with the standard NACA airfoils/ KAMM tail that no longer have sharp edges on the back. The softened angles improve performance even when the airflow is disturbed.

The inside of the front fork has been widened by 7 mm, making it 13.6% wider than the Cento10PRO. In doing so, we moved the fork blades away from the wheel, reducing turbulence and improving aerodynamics.

Lightweight and Responsive
The new aerodynamically optimised profiles helped us eliminate extra weight in the frame’s construction. The shape has no sharp edges and, therefore requires less material and less resin in the corners. This improves the homogeneity of the inside, reducing the frame’s weight to a mere 870 grams. The assembled bike with top-of-the-range specifications weighs 6.8 kg.

The Filante monocoque handlebar is made of the same carbon we use for the Wilier 0 SLR. Thanks to the different types of carbon we used in combination with the Liquid-Crystal Polymer, the unique fibre positioning and the construction technology, we have reached an absolute level of lightness and stiffness.

The lower overall weight compared to the exceptional stiffness increases STW by 12.5%. This improvement is clearly felt with the steering precision and the feeling of safety at high speeds.

Handlebar and integrated cables
In addition to being lightweight, (350 grams for the 101x42 size) the new integrated carbon monocoque Filante Bar handlebar houses the brake and derailleur cables, directing them toward the inside of the frame. Its design is very simple, with sinuous and rounded lines for maximum grip ergonomics.
