The Bianchi Oltre Pro Ultegra Di2 12sp is a high-performance aero machine that sits just below the flagship RC (Reparto Corse) model. It is the "thinking rider's" aero bike, utilizing the same revolutionary aerodynamic platform as the top-tier build but incorporating Countervail (CV) technology—a viscoelastic carbon material that cancels 80% of road vibrations. This makes the Oltre Pro significantly more comfortable for long-distance racing and high-speed solo efforts compared to standard stiff aero frames.
The 57cm frame (XJ) is built for the "System-of-Systems" philosophy, where every component—the frame, the integrated cockpit, and even the rider—is treated as a single aerodynamic unit. This model features the Air Deflectors on the head tube, which are designed to channel air into low-pressure zones behind the rider's legs.

Key Technologies
Air Deflectors: Patented winglets mounted to the sides of the head tube that divert air flow to create a low-pressure channel around the rider's moving legs, reducing overall drag.
Countervail (CV) Technology: Exclusive to the "Pro" model, this carbon layup prevents muscle fatigue by neutralizing high-frequency road buzz without sacrificing the frame’s lateral stiffness.
Vortex Generators: Strategic ridges on the frame and integrated handlebar that "trip" the air into a controlled turbulent boundary layer, allowing air to stick to the frame longer and reduce wake.
Reparto Corse RC50 Wheels: These 50mm deep carbon wheels are designed in-house specifically for this frame, offering a perfect balance of crosswind stability and pure straight-line speed.
