Bianchi Specialissima Pro Ultegra Di2 12sp Powermeter

The Bianchi Specialissima PRO Ultegra Di2 is a high-performance carbon racing bike, designed to offer an ideal balance between lightness, stiffness, aerodynamics, and control.

It is a true all-rounder racing bike: fast on climbs, precise on descents, responsive to changes in pace, and stable at high speeds. It is aimed at sporty and advanced cyclists looking for a bike with a competitive character, yet comfortable and balanced enough to tackle granfondos and long days in the saddle.

HM carbon frame with Countervail® technology

The Specialissima PRO frame is made of high-modulus carbon fiber and integrates the Bianchi Countervail®, developed to reduce vibrations transmitted from the asphalt.

This technology helps limit muscle fatigue, improve control on rough surfaces, and maintain greater precision on fast descents. At the same time, the frame retains high torsional stiffness, essential for effectively transferring power during accelerations, surges, and high-intensity climbs.

The geometry maintains a racing setup, but offers balanced and predictable handling even over longer distances.

Full integration and aerodynamic lines

The fully internal cable routing, combined with the Acros ICR headset, improves aesthetic cleanliness and reduces exposed cabling.

The front-end integration also helps optimize aerodynamic efficiency, creating a continuous line between frame, fork, and cockpit.

The high-modulus full carbon fork, also equipped with Countervail® technology, ensures directional precision, cornering stability, and greater control on fast or uneven sections.

Shimano Ultegra Di2 12-speed drivetrain

The Shimano Ultegra Di2 electronic drivetrain offers fast, precise, and reliable shifting in all conditions.

The 52/36T chainset and 11-30 cassette prioritize speed, pedaling fluidity, and gear continuity, making it particularly suitable for mixed routes, competitions, and fast granfondos.

The 4iiii Precision 3 power meter integrated into the crankset allows you to monitor your power output and manage training, races, and effort distribution with greater precision.

Shimano Ultegra disc brakes

The Shimano Ultegra hydraulic braking system guarantees power, modulation, and consistency even on long descents or in changing weather conditions.

The Shimano RT-CL800 rotors with Ice Technologies technology promote heat dissipation and maintain stable braking even during the most intense use.

Velomann Plutonium carbon wheels

The Velomann Plutonium carbon wheels, with a 50 mm profile, increase aerodynamic efficiency and lateral stiffness, offering fast and precise behavior at high speeds.

The Pirelli P Zero Race SL TLR 28 mm tires combine low rolling resistance, grip, and comfort, with the option to set up the wheels tubeless.

Reparto Corse integrated cockpit

The Bianchi Reparto Corse integrated carbon cockpit completes the setup with high front-end stiffness, full cable integration, and a clean, efficient riding position.

The cockpit dimensions vary according to the frame size, to ensure a proportionate configuration consistent with the bike's geometry.

Carbon saddle and seatpost

The fully carbon aero seatpost helps keep the weight down and maintain a harmonious line with the frame.

The Velomann Mitora 139 Lite saddle, featuring a central cutout and carbon rails, offers a good balance of support, lightness, and comfort on long rides.
