Specialissima Pro / Ultegra Di2 12Sp

The Bianchi Specialissima Pro Ultegra Di2 12sp is the "Goldilocks" of the high-performance road world—an elite-level all-rounder that refuses to compromise between weight, stiffness, and comfort. While many climbing bikes focus solely on the scales, the Specialissima Pro was re-engineered using computational fluid dynamics (CFD) to ensure it slices through the wind as efficiently as a dedicated aero bike.

The defining characteristic of the "Pro" frameset is the inclusion of Countervail (CV) technology. By embedding this viscoelastic material within the high-modulus carbon layers, Bianchi has created a frame that cancels up to 80% of road vibrations. This results in a smoother ride that reduces muscle fatigue, allowing you to descend with more confidence and arrive at the base of the next climb feeling fresher.

Key Technologies

• Countervail (CV) Technology: This is the only model in the latest Specialissima lineup to feature CV. It’s designed specifically for riders who want the performance of a WorldTour frame but need the vibration damping for long, real-world road surfaces.

• Integrated Carbon Cockpit: The one-piece handlebar and stem setup is incredibly stiff for out-of-the-saddle sprinting and hides all hydraulic hoses from the wind, providing a significant aerodynamic advantage at high speeds.

• Aero-Optimized Climbing Geometry: The head tube and fork blades borrow their profile from aero-racing designs to minimize drag, while the steep seat tube angle keeps you in an ideal position for high-cadence climbing.

• Palladium 33 Carbon Wheels: A 33mm rim depth offers the perfect balance—deep enough to provide an aero advantage on the valley floors, but shallow and light enough to keep the bike's total weight near the UCI limit.
