Bianchi Oltre XR4 CV Frameset
The wait is over the Bianchi’s greatest allround racing frame has the most comfortable carbon technology added Countervail Cv for short, used on the Specialissima and of course the Infinito CV. The statistics read for themselves 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 Bianchi’s carbon frames and forks.

Bianchi Oltre XR4 CV Frameset is designed with advanced CFD (Computational Fluid Dynamics) simulation software to predict the impact of aerodynamic drag.In the wind tunnel test, a special fluorescent paint (borrowed from 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. Bianchi claim a 20 watt power gain compared to Oltre XR2.

BIANCHI CV
BIANCHI CV is Bianchi's INTEGRATED VIBRATION CANCELLING SYSTEM for cycling, with innovative and exclusive use of Materials Sciences Corporation's patented Countervail® material.

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.

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 tested in NASA aerospace operations.

STAY AERO FOR LONGER
Countervail® cancels road vibrations and reduces turbulence in the frame that affect its performance. it enhances peak power output by maximizing the vibrational dissipation in the surrounding polymers.

Advantage: hold your extreme aero position at high speeds for longer and maximize your aerodynamic advantage

MAXIMUM CONTROL AT HIGH SPEED
Countervail® provides unparalleled vibration cancelling properties, ensuring the frame’s optimum performance at high speed. Countervail® eliminates road buzz to maximize ride control, and reduces muscular fatigue.
