In case you've been living under a rock, the age of the aero road bike is upon us, which makes Wilier's timing perfect in introducing the Cento1 Air Dura Ace Ultegra 11 Complete Road Bike. As the next evolution of the Cento1 SR, you already know that this is a thoroughbred that loves to go fast. And while the aerodynamics are impressive, it's the smooth, controlled ride that's had the Cento1 Air turning so many heads this year. The Cento1 Air benefits from the experience gained in developing what Wilier calls the Twin Foil. The aggressive profiling extends from the leading edges of the fork blades, all the way back to the dropouts. And while most aero road bikes suffer in ride quality due to the design constraints of low drag tube shapes, this type of compromise was viewed as unacceptable during the development of the Cento1 Air. To combat the poor handling exhibited by most of its competitors, the Cento1 Air was built with a massive tapered head tube and steerer tube, which yields surgically precise steering, even on high speed descents. The heavily profiled down tube should yield under power, but with the oversized bottom bracket shell, your watts won't be wasted in frame deflection. Developed in cooperation with FSA, the BB386EVO is a competitor dwarfing 86. 5mm wide and has a diameter of 46mm. Wilier estimates that the new bottom bracket increases rigidity by 30%, while reducing power dispersion to almost zero. Additionally, this shell's width provides Wilier with the ability to widen the seat and down tube diameters by around 20mm. This drastically increases rigidity, while also promoting an efficient power transfer to the rear triangle. But, this also permits Wilier to decrease the tube's wall thickness, further shedding grams. You'll also find that the BB386 EVO was developed to use press fit bottom bracket cups, eliminating the need for alloy inserts in the shell. Of course, this also shaves a good deal of unnecessary weight. Altogether, Wilier cred...
