Bianchi Oltre XR4 Rival eTap AXS Airbeat Disc Road Bike 2022
Race-proven on the premier stages of cycling, the Bianchi Oltre XR4 Rival eTap AXS Airbeat Disc Road Bike combines state of the art carbon technology with classic Italian flair, delivering on its premium, superbike status. Engineered through the use of fluid dynamics software, every millimetre of the Oltre’s surface is optimised to provide the utmost aerodynamic advantage.
Designed to eliminate road vibration, the Countervail technology found within this frame combines carbon fibre with a viscoelastic compound, which sees reduced rider fatigue and enhanced levels of control. Found only on Bianchi’s highest-end models, this class-leading technology allows the user to ride harder and faster than ever before, all without the penalties associated with stiff, race-focused carbon layups.
Fully wireless, the SRAM Rival eTap drivetrain is a mechanic's dream. Requiring no internal routing and being exceptionally simple to set up, this futuristic drivetrain elevates your shifting, delivering crisp, precise gear changes across its wide-range, 12-speed block. Wrapped around the aero-optimised Fulcrum Airbeat 550 disc wheels, this model is equipped with fast-rolling Pirelli P Zero Race tyres.
