The all-new S-Works Venge ViAS Di2 was developed with one objective in mindâto be the fastest bike in the world. The design for this bike started with building our own Win Tunnel, and with more than 1000 hours of testing, prototyping, and refining, we can say with confidence that we nailed our objective. The high level of performance starts with a Rider-First Engineeredâ¢ frame and fork that feature a new level of aerodynamics. This is coupled with the added benefit of the Roval CLX 64 wheelsetâthe fastest wheels we've ever made. Along with the zero-drag brakes and Aerofly ViAS cockpit, the S-Works Venge ViAS Di2 is, quite simply, the fastest bike in the world. Use the Venge ViAS sizing tool to replicate your current bike fit.
