asymmetric rear arms
The drive-side chainstay has been modified to better facilitate the forces applied to it by the actuation of the drivetrain, providing enhanced stability and ultra-efficient power transfer.
This special technology is applied on the rear arms. It dampens and dissipates vibrations over all kinds of road surfaces.
IC integrated cables
The brake and derailleur cables flow inside the frame. This allow the frame to be aerodynamic, protect and cover the cables
Wilier Triestina still insisted on a design that allowed for fine-tuning of rear wheel position and therefore of the cogset’s orientation in relation to the rear derailleur. This enables optimal wheel alignment, aerodynamic positioning and smooth shifting. Thanks to our innovative solution providing 6mm of adjustability, wheel base and distance from tire to the rear of our truncated seat tube airfoil are customizable. This enables both aerodynamic and bike handling optimizations, as well as making wheel changes fast and simple.
IF integrated fork
The handling of a Wilier bike is one of its most treasured attributes. We continually search for ways to further improve the solid feel at the front end, which has led to some of the most significant of the Cento1 SR’s enhancements. We found that a new way of positioning the down tube and top tube with respect to the head tube creates a virtual increase of the head tube’s height, which makes it 14% stiffer in terms of torsional rigidity. The top tube approaches the head tube at a downward angle while the down tube is angled upwards as it joins the head tube and the Integrated Fork. This junction is traditionally like the point of a triangle, but this new angle and positioning makes it more like a square, which is stiffer. The back of the fork’s brake hole is tucked into the down tube, keeping it clean and protected from the elements. The Integrated Fork design also creates an aerodynamic profile that reduces drag. Drawing from research implemented in development of our Twin Blade, the Cento1 SR’s fork legs are designed for optimal stability and aerodynamics. Like the proven Kamm truncated tail concept implemented in our time trial models, both the Cento1 SR’s integrated seatmast and fork legs benefit from this structural innovation, thereby attaining a perfect balance of lightweight, aerodynamics and steerability.
What we commonly refer to as “carbon” is actually a composite of fibers and epoxy resin. The resin’s function is to join and bond the fibers, as well as protect the overall structure from external forces. In order to avoid potential points of weakness that could result from micro-gaps in a composite layup, we’ve implemented an ultra low density nanoparticle Zinc Oxide (“ZnO”) resin. This results in a stronger composite with higher resistance to impact while enabling us to reduce the weight of our frames due to its superior structural integrity. What this means out on the road is improved durability and amazingly responsive handling - the hallmark of our frames.
