STAY AERO FOR LONGER ON THE NEXT GENERATION AERO RACE MACHINE, THE BIANCHI OLTRE XR4 WITH INNOVATIVE COUNTERVAIL® CARBON VIBRATION-CANCELLING TECHNOLOGY.
Your body contributes about 80% of aerodynamic drag so staying aero for longer means fast times. The Oltre XR4’s revolutionary Countervail® vibration cancelling technology increases control, reduces fatigue and frame turbulence that affect performance, so you will be able to hold your most aero position at high speed for longer to maximize your aerodynamic advantage. 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. Developed for NASA by the Materials Sciences Corporation, Countervail® is a composite-material system that combines viscoelastic carbon material within DXQLTXH¿EHUSUHIRUPWRFDQFHOURDGYLEUDWLRQVDQGUHGXFHWXUEXOHQFHVLQ the frame that affect its performance. Countervail®, exclusive to Bianchi CV frames and forks, enhances rider peak power output by maximizing the vibrational dissipation in the surrounding polymers. Aggressive race geometry, lightweight, highly aerodynamic and with Countervail®’s unique vibration-cancelling technology, the Oltre XR4 keeps you in position to race faster.
COUNTERVAIL® CARBON MATERIAL IS INTEGRATED INTO THE ENTIRE FRAME AND FORK.
