Wilier Filante SLR ID2 - F28 Luna Grey Iridium Glossy

Be your fastest.
In the theatre of speed, there is only you.
The Filante SLR ID2 represents the ultimate evolution of Wilier’s aerodynamic racing
bikes.
Developed hand-in-hand with the Groupama - FDJ 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.
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-therange
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.
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.
