BIANCHI OLTRE XR4 CV DURA ACE Di2 12v

The OLTRE XR4 CV is a pure aero road bike, born for high-level competition. It combines extreme aerodynamic profiles, exceptionally high torsional stiffness, and Countervail® anti-vibration technology, delivering maximum speed with superior control over long distances and on rough asphalt surfaces.

The carbon frame with CV (Countervail) technology integrates a viscoelastic material that reduces vibrations from the road surface. The result is less muscle fatigue, greater stability on descents, and more precision when pushing hard on the pedals, without losing the responsiveness typical of a racing bike.

The aero shapes of the frame and fork work to reduce air resistance at high speeds, making this bike perfect for fast races, flat terrain, breakaways, and rolling sections where maintaining a high pace for a long time matters.

The build with Shimano Dura-Ace Di2 12-speed represents the pinnacle of electronic technology: instantaneous, precise, and perfectly aligned shifting even under load. The hydraulic disc brakes ensure benchmark power and modulation in all conditions.

The high-profile Vision SC 55 wheels complete the aerodynamic character, offering great rolling smoothness and stability at high speeds, while the integrated Vision Metron 5D ACR carbon cockpit maximizes front-end stiffness, aerodynamic cleanliness, and steering precision.

It is the ideal choice for those who want an aero carbon racing bike with anti-vibration technology, capable of combining pure speed, control, and evolved comfort.
