2021 Bianchi Oltre XR4 Non Disc - Ultegra

YThe Oltre XR4 is a bike driven to perform. Its precision handling, combined with vibration-cancelling Bianchi CV system, provides incomparable control. Perfect power transfer means every watt you push through the pedals takes you closer to the win. If you want it bad enough, the Oltre XR4 is the tool to take you to the top.

CUTTING EDGE OF AERODYNAMICS
Oltre XR4 is designed with advanced CFD (Computational Fluid Dynamics) simulation software to predict the impact of aerodynamic drag and is wind tunnel tested

FLOW VISUALIZATION
A special fluorescent paint (borrowed form F1 Car design) is flown over the frame and fork’s surfaces at race speed. The interpretation of their trace patterns and intensity reveal the aerodynamic performance of every aspect

AERO HEADTUBE
Tapered headtube takes inspiration from Aquila CV aero profiles and is designed to integrate the aero handlebar and the headset.

Bianchi has developed two different top cup for Vision Metron5D handlebar and conventional stems

AERO SEATPOST
Aero seatpost with integrated look and adjustable head clamp offset 25mm or -10mm

ENGINEERED WITH BIANCHI CV SYSTEM
Oltre is engineered with the Bianchi CV System to cancel the road vibration. The result is in a smooth ride and a racer who can stay focused in his fastest, most efficient aerodynamic position for longer.

Bianchi CV system cancels 80% of road vibration thanks to the use of a unique composite material integrated in Bianchi’s high-performance carbon frames and forks. The Bianchi CV vibration cancelling system combines viscoelastic material together with a special carbon fiber architecture to dissipate vibration.

Advantages for the rider are more control, less muscle fatigue and more energy.

TESTED IN EVERY RACE SITUATIONS
Traditional passive damping in frames using superficial rubber inserts and isolators are marginally effective compared to the integrated vibration cancelling system developed by Bianchi for cycling and proven in the extreme conditions.
