Description
An all-round performer that's incredibly fast, incredibly aerodynamic, all the while remaining comfortable; introducing the Bianchi Oltre XR4 SRAM RED eTap AXS Disc Road Bike. A key technology is Countervail, a carbon composite that cancels out vibrations. This material was developed by Bianchi in a collaboration with the Materials Sciences Corporation and reduces road buzz by 80% while improving strength and stiffness so power output is maximised.
Complementing the quality of the frameset is the SRAM RED eTap AXS groupset. Electronic and wireless, the components offer unmatched precision, reliability and shifting speed, along with powerful hydraulic disc braking, effective in all conditions. The Vision Metron 55 wheels were developed for aerodynamics without compromising on stability.
Please note: Build as per technical specifications. Images for representation of colourway only.
