Speed made to endure Those who will take on any road, go any distance, and ride in any weather need a bike as strong and dependable as they are. With a high-performance carbon frame and telepathic handling, the RVR will satisfy the most discriminating endurance riders. There are no gimmicks, just efficiency, simplicity, and comfort. Ride as long as you wish. The RVR will never hold you back. Aerodynamic Design To make one of the most aerodynamic endurance bikes ever designed, the carbon frame was shaped through extensive CFD work and testing in the A2 wind tunnel by an engineering team that has developed record-breaking aero designs. Endurance Geometry Fine-tuned geometry puts riders in a more upright and relaxed position. This keeps you feeling fast and comfy during your longest rides and on imperfect road surfaces, letting you step on the gas harder and dig deeper late into every ride. Increased Comfort Suffer less during all-day adventures with a carbon frame lay-up engineered for increased vertical compliance that absorbs vibration and dampens impacts without sacrificing pedaling efficiency. Add extra squish with clearance for wider tires.
