Bianchi Oltre XR4 CV Dura-Ace Road Bike 2020 (Fulcrum Racing 418)
Packed with innovation, the Bianchi Oltre XR4 CV Dura-Ace Road Bike (Fulcrum Racing 418) has been created to give you a performance advantage no matter the terrain or conditions. The frameset is aero optimised to reduce drag and with Countervail, you’ll be able to put in your all for longer, in complete comfort. This technology cancels 80% of vibrations coming up off the road, ultimately reducing fatigue that can slow you down, while also improving control.
A Shimano Dura-Ace mechanical groupset offers compact shifting, balancing high and low gears for climbing, descending and sprinting, while the direct mount brakes will stop you fast when required, providing good modulation. Fulcrum Racing 418 wheels balance stability, weight and aerodynamics, making an excellent all-rounder, and they're fitted with 25c Vittoria tyres. Reparto Corse finishing kit and a Selle Royal saddle round off the build nicely.
- 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
- Fulcrum Racing 418 wheelset
- Shimano Dura-Ace mechanical and FSA mix drivetrain
