Bianchi Oltre XR4 Disc Ultegra Di2 (2021)

Share

 

The Oltre has always been Bianchi's most aerodynamic and stiffest road bike, but the Oltre XR4 takes both of these properties to new levels, all thanks to Countervail - dedicated tuning of Countervail within the carbon lay-up of every tube provides maximised aero advantage and control at high speeds.

The Oltre XR4 was designed to be at the absolute cutting edge of aerodynamics thanks to advanced CFD and Flow Visualisation – technologies borrowed straight from aerospace and F1 car design. When combined with advanced analysis, the resulting data enabled Bianchi  to achieve a significant aerodynamic saving of 20 watts over their already hugely efficient XR2 frameset.

 

So this is a super stiff, aerodynamic bike that is actually quite a comfortable ride. XR4 is available as a complete bike in various specification and frame colour but also as a frameset which can be built to exact personal specs.
