Bianchi Oltre XR4 CV SRAM RED eTap AXS Road Bike 2020
Bianchi’s Oltre XR4 CV RED eTap AXS Road Bike has been engineered for performance. It’s stiff, aerodynamic and fast, yet there’s no compromise on comfort thanks to Countervail technology. Absorbing 80% of vibrations, fatigue is reduced and control improved.
SRAM’s electronic and wireless RED eTap AXS 12-speed groupset performs flawlessly with precise, reliable and fast shifting across the wide range of gears. The SRAM brakes have a direct mount design and offer modulation and power in all conditions. Fulcrum Racing Zero C17 wheels fitted with Vittoria Corsa graphene 25c tyres provide you with efficient power transfer, smoother faster rolling and excellent protection against punctures.
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
- 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
