The S-Works Venge ViAS Disc w/ eTap is more than just a bike. Nearly every single piece of it was redesigned from the ground up. Every facet was examined, and the result is a bike with supreme braking and a 45-second advantage, compared to the Tarmac, over 40km. It's also Rider-First Engineered™ to ensure that every frame size experiences uniform performance, plus front-end stiffness was increased by 30% over the Tarmac. As one of the first elements to hit the wind, Specialized realised that most stem & bar offerings cause too much aerodynamic drag. To achieve the best solution, while also interfacing with the frame, they found a negative 17-degree stem was the best option. Most riders aren't flexible enough to ride in such an aggressive position, though, so they designed the Aerofly bars with a positive rise that replicates your most efficient position. This resulted in a bike that has next-to-no visible cables.
