Description
Combining Italian flair with a top spec, the Bianchi Oltre XR4 Dura-Ace Di2 Disc Road Bike looks as good as it feels to ride. The carbon frame and fork have been created using Computational Fluid Dynamics to ensure every detail is aerodynamically optimised, and include Bianchi's patented Countervail technology to absorb much of the harshness of the roads, reducing fatigue and allowing you to ride comfortably for longer. This carbon composite material also strengthens and stiffens the frame.
A perfect pairing for a frameset of this calibre, Shimano's top electronic components - Dura-Ace Di2 - shift fast with precision from just a light touch of the lever, and hydraulic disc brakes work effectively in all weather conditions for confidence at speed. The Vision 55 SC wheels are lightweight and versatile, with a 55mm depth and full carbon rim construction. Up front, the Vision Metron 5D integrated bar and stem look sleek and minimise drag, along with the aero seatpost.
Please note: Build as per technical specifications. Images for representation of colourway only.
