Bianchi Oltre XR4 Ultegra Di2 Disc Road Bike 2019
Aerodynamic design meets improved braking performance in the Bianchi Oltre XR4 Ultegra Di2 Road Bike. Engineered using Computational Fluid Dynamics (CFD), every aspect of this outstanding bike has been optimised and refined to reduce drag, and the Metron 5D ACR aero handlebar and stem system provide a more efficient front end. Tested in collaboration with professional riders, you can be sure this bike is made to perform at the highest level. One of the highlights is Countervail® technology, absorbing 80% of vibrations for a significantly smoother ride. The frameset has been built up with Shimano's Ultegra Di2 drivetrain, for instant, smooth shifts at just the light touch of a button.
- 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 the vibration resulting in increased control and reduced muscle fatigue. The result with the Oltre XR4 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-R8070, hydraulic disc brakes, flat mount calipers / Shimano SM-RT800 Center lock, 160mm diameter rotors
- Shimano Ultegra Di2 drivetrain
