Description
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.
Please note: Bike is supplied with the Fulcrum Racing 418 disc brake wheelset indicated in spec, not the Fulcrum Racing Quattro wheelset pictured.
