Bianchi Oltre XR4 CV Dura-Ace Road Bike 2020 (Fulcrum Racing Zero C17)
Aerodynamic, stiff, and fast, the Bianchi Oltre XR4 CV Dura-Ace Road Bike (Fulcrum Racing Zero C17) will help you push yourself to the next level. Key to its performance is the Countervail technology, a carbon composite material in the frame and fork that cancels out 80% of vibrations, smoothing out the roads and reducing fatigue, allowing you to work harder for longer, keeping your muscles fresh. The frameset has been created using Computational Fluid Dynamics, optimising aerodynamics in every detail. The Vision Metron integrated stem and bar play a part in this too, keeping things clean up front.
Shimano's flagship Dura-Ace groupset offers the best of mechanical shifting and the compact gearing will help you spin up the hills without limiting speed when it comes to sprinting and fast descents. The shifting is precise and reliable and the direct mount braking modulated and powerful for control and confidence at speed.
Highlights
- Computational Fluid Dynamics (CFD), to refine and optimise every aspect of the Oltre XR4 frameset, to ensure the new XR4 is a masterpiece of aerodynamic design
- Bianchi’s leading aero design with direct mount brakes delivers a superior aero road experience
- The Oltre XR4 frame and fork are designed to accommodate wider tyres. The extra clearance enhances comfort and grip
- Countervail®, exclusive to Bianchi CV models – cancels 80% of vibrations resulting in increased control and reduced muscle fatigue. The result is a smooth ride and a racer who can stay focussed in their fastest, most efficient aerodynamic position for longer
- Fulcrum Racing Zero C17 wheelset
- Shimano Dura-Ace mechanical drivetrain
