MAXIMUM AERO ADVANTAGE
Bianchi engineers have created their most aerodynamic road frame to date. Through CFD software, extensive wind tunnel testing at the F1 facility in France, and Flow Visualization, the XR4 can be piloted at 50k/hr and require 20 watts less power from the rider to hold that speed versus the outgoing Oltre XR2 platform. Since the XR2, every tube on the XR4 has been redesigned from the ground up with major focus on the first 40cm of the bike. None is more obvious than the use of the Vision Metron 5d handlebar, the bold fork profile, head tube shaping, and top tube/ down tube design.
Excellent stability at high speeds makes Bianchi's XR4 ideal when tackling different types of surfaces during fast accelerations, mountain descents, and super high-speed corners. Bianchi’s Countervail construction in the XR4 reduces muscle fatigue; allowing the rider stability, maximum power, and control for holding an aero position during long periods of time. A direct mount braking systems provides powerful braking performance for halting the XR4 during high speed mountain descents.
BIANCHI CV INTEGRATED VIBRATION CANCELLING SYSTEM
Bianchi collaborated with Materials Sciences Corporations to develop our innovative and exclusive use of MSC's patented Countervail® integrated vibration cancelling system for cycling. Countervail® is a patented viscoelastic carbon material with a unique fiber architecture that cancels up to 80% of vibrations while increasing the stiffness and strength of our carbon frames and forks.
Countervail is embedded within the layup of Bianchi CV high-performance models: Specialissima, Oltre XR4, Infinito CV, Methanol CV, and Aquila CV. Each application of CV is engineered to optimally perform within that frame’s specific use and riding environment.
PROVEN IN NASA AEROSPACE OPERATIONS
Traditional passive damping in frames using superficial rubber inserts and isolators are marginally effective compared to the integrated carbon Countervail® system developed by Bianchi for cycling and proven in the extreme conditions of NASA aerospace operations.
"The Davos Rides powered by Bianchi" project consists of two premium performance bike tours in cooperation with world-renowned operator Thomson Bike Tours. The two DavosRides by Bianchi are set to take place in summer 2017: August 2nd - 7th and August 30th - September 4th
