The pursuit of maximum performance and continuous technical evolution drives the soul of those who design, engineer, and build bicycles. If you add to this that pinch of competition that comes from being part of a WorldTour team, then the sense of challenge amplifies. At Wilier Triestina, this is exactly what happened when it came to making the Filante SLR ID2 Firelight Red which will be provided to the team's athletes Groupama-FDJ.
Let's start with the most prominent aspect: the color. Compared to past seasons, white gives way to a bright red, hence the name Firelight Red, which represents the exact moment when the heat of the fire meets the oxygen and releases its maximum energy.


United
The Filante SLR will still be the bike that Romain Gregoire and his teammates will also use it in the 2026 season, with its debut scheduled for the Tour Down Under in Australia. Con la nuova Filante SLR ID2 However, Wilier wanted to unite even more with the French WorldTour team, creating a frame and a livery capable of uniting and creating a clear and well-rooted visual identity between athletes and bicycle.
An important contribution came from the Groupama-FDJ athletes, who were actively involved in the creation of the Filante SLR ID2. Their experience and technical sensitivity has allowed them to create an even higher-performance and faster bicycle., a means with which to challenge the best cyclists in the world.


New standards
The pursuit of performance and maximum technical efficiency when developing and designing a bicycle must not be an end in itself, but rather be geared towards use by the rider. Efficiency, but also comfort and control become fundamental factors, so as to have a safe and stable ride at all times and in all phases of the race.
There's no shortage of new features and technical updates, especially in the frame construction. One of the most delicate areas from a design perspective, the down tube, It was developed with the aim of having the least possible aerodynamic resistance. Furthermore, Wilier has also focused a lot on reducing the exposure of the water bottles to air as much as possible. The system is called Aerokit and was created in collaboration with Elite Cycling in order to provide a functional and performance-oriented kit.
From a technical point of view, the Aerokit works like a real spoiler, capable of keeping the air more stable and less disturbed around the chassis. Compared to traditional systems, aerodynamic resistance is reduced by more than two thirds.




Benefits in numbers
In modern cycling, performance translates into numbers and data. The new Wilier Filante SLR ID2 features a different frame shape but still weighs the same: 860 grams in size M. However, the changes come when it comes to analyzing performance and translating it into technical data. Rigidity has increased by 7,49 percent compared to the previous model.
In terms of aerodynamic drag, the numbers show an extremely high advantage, which for the Filante SLR ID2 stands at 13,1 percent. If we add the athlete to this, the aerodynamic advantage remains in the order of 5,22 percent compared to the Filante SLR ID1.
If you look at the watts, the energy saving needed to maintain a speed of 40 kilometers per hour is 4,91 percent. Last significant data: to travel 70 kilometers at 290 watts the time taken by the Filante SLR ID2 is 1 hour, 43 seconds and 15 hundredths. With a saving of 1 minute and 45 seconds.
