Pairing a Bianchi Oltre XR4 Disc frameset with top-end Shimano Dura-Ace Di2 components and Vision 55 wheels results in a race-ready road bike that's light, stiff and aerodynamic.

It remains extremely comfortable, offering excellent control and a smooth ride feel thanks to Countervail technology used in the frame and fork.

Bianchi Oltre XR4 Dura-Ace Di2 Disc Road Bike 2020

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.


  • Computational Fluid Dynamic (CFD), to refine and optimise every aspect of the Oltre XR4 frameset, to ensure the new XR4 Disc is a masterpiece of aerodynamic design
  • Bianchi’s leading aero disc design 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
  • The Vision Metron 5D bar and stem gives the Oltre XR4 the cleaner, more aero front end for added speed and efficiency
