STAY AERO FOR LONGER = GO FASTER
Your body contributes about 80% of aerodynamic drag on the bike, so staying in your most aero position as long as possible is vital for fast times. With our new Bianchi Oltre XR4, enhanced with revolutionary Countervail® vibration cancelling technology that increases control, reduces fatigue and frame turbulence that affect performance, you will be able to hold your most aero position at high speed for longer to maximize your aerodynamic advantage.
Developed for NASA by the Materials Sciences Corporation, Countervail® is a composite-material system that combines viscoelastic carbon material within a unique fiber preform to cancel road vibrations and reduce turbulences in the frame that can affect its performance. Countervail® enhances the rider’s peak power output by maximizing the vibrational dissipation in the surrounding polymers. Countervail® is exclusive to Bianchi CV frames and forks for unparalleled cancellation of vibration, ensuring the frame’s optimum performance at peak power output and high speed, and eliminating road buzz to reduce rider fatigue.
Aggressive race geometry, lightweight, highly aerodynamic and with Countervail®’s unique vibration-cancelling technology, the Oltre XR4 keeps you in position to race faster. Oltre XR4 has been developed and tested in cooperation with Bianchi-supplied World Tour Team LottoNL-Jumbo, and has already collected remarkable successes on the World stage with Dylan Groenewegen and Sep Vanmarcke. Oltre XR4 is also currently used by the Dutch team at the Tour de France.
Oltre XR4 was designed to be at the absolute cutting edge of aerodynamics thanks to advanced CFD and Flow Visualization – technologies borrowed straight from aerospace and F1 car design. When combined with advanced analysis, the resulting data enabled us to achieve a significant aerodynamic saving of 20 watts over our already hugely efficient XR2 frameset.
In a wind-tunnel, Bianchi’s technicians flew fluorescent paint over the frame and fork’s surface at race speed and interpreted their trace patterns and intensity to reveal the aerodynamic performance of every aspect.
