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.
