Bianchi Oltre XR4 CV Dura-Ace Di2 Road Bike 2020
Bianchi’s Oltre XR4 CV Dura-Ace Di2 Road Bike is a top performance road race machine with the componentry to match. Engineered for an aerodynamic advantage, it also features unique Countervail technology, claimed to cancel out 80% of the buzz from the roads for reduced fatigue and improved control. Designed for wider tyres, you can further this benefit even more, for an incredibly smooth and comfortable ride.
Shimano’s Dura-Ace Di2 electronic components are the brand's top-end option, and shifting is fast and precise at just a light touch of the lever. Mid-compact gearing is often chosen by serious racers that require big enough gears for sprinting and descending without losing required climbing ratios. Direct mount brakes offer modulated stopping that’s powerful and reliable in all conditions. The Fulcrum Racing Zero C17 wheels are a quality alloy set that balance low weight, durability and performance perfectly. A combined Vision Metron 5D bar and stem keep the aesthetics clean and reduce drag at the front end.
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 focused in their fastest, most efficient aerodynamic position for longer
- The Vision Metron 5D bar and stem gives the Oltre XR4 the cleaner, more aero front end for added speed and efficiency
- Fulcrum Racing Zero C17 alloy wheelset and Vittoria Corsa 25c tyres
- Shimano Dura-Ace Di2 drivetrain with direct mount brakes
