The fastest version of yourself
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.

Elegant Color and Very Well Made Vest
Size: 14, Color: Light Grey, Size: 14, Color: Light Grey
The vest is really nice and great quality, but it does run a little smaller than expected. I would suggest sizing up if you want a more comfortable fit. Other than that, it looks very sharp and well made.
