Specialized's Venge ViAS Pro Disc UDi2 was designed for one purpose and one purpose only: to be the fastest bike on the planet. Boasting awesome ride characteristics tuned by Specialized pro riders, its FACT 11r carbon frame was tuned and tweaked in the wind tunnel for maximum aerodynamics. Its blade-like tapered fork meshes seamlessly with the massive aero down tube while hiding the front brake. The down tube works with the rear wheel cutout and asymmetrical, airfoil-shaped seatstays to minimize drag. Shimano Ultegra Di2 shifting offers 11-speeds of electronic wonderment. Shifts are as precise as it gets, dropping chains becomes a rarity, and the trim adjust up front ensures that chain rub is a thing of the past—no matter how extreme your cross-chaining gets. Roval carbon wheels slice through the wind and fly up climbs, while Shimano hydraulic-disc brakes provide powerful, consistent speed control on the way back down. Specialized even created their own aerodynamic handlebar and stem combo to further enhance this bike's aerodynamic efficiency.
