Bianchi Oltre XR4 CV Ultegra Di2 Disc Road Bike 2020
Incredibly fast and aerodynamic, the Bianchi Oltre XR4 CV Ultegra Di2 Disc Road Bike is engineered for drag reduction. Countervail technology absorbs 80% of vibrations, consequently reducing fatigue in the body so you can work harder for longer. The Vision Metron 5D ACR aero handlebar and stem system look slick and ensure the air flows more efficiently over the front end.
Complemented perfectly by Shimano's Ultegra Di2 components, weight is kept low, shifting is smooth and precise, and hydraulic braking powerful, with no drop in performance when the roads are wet. The bike rolls on Fulcrum Racing 418 wheels that are durable, stiff and strong.
- Bianchi’s leading aero design meets upgraded disc braking performance to deliver a superior aero road experience
- The Oltre XR4 Disc 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 Metron 5D ACR bar and stem gives the Oltre XR4 the cleaner, more aero front end for added speed and efficiency
- Fulcrum Racing 418 disc brake wheelset
- Shimano BR-R8010, hydraulic disc brakes, flat mount calipers / Shimano SM-RT800 Center Lock, 160mm diameter rotors
- Shimano Ultegra Di2 drivetrain
Please note: Bike is supplied with the Fulcrum Racing 418 disc brake wheelset indicated in spec.
