Bianchi Infinito Pro Ultegra Di2 4IIII PWM

The Bianchi Infinito Pro with Shimano Ultegra Di2 is a high-end endurance road bike designed for those who desire the utmost in comfort over long distances, precise handling, and modern performance. It is a platform developed to tackle gran fondos, long road rides, and challenging routes with an efficient riding position, smooth pedaling, and top-tier technical specifications.

The Bianchi Infinito Pro frame is engineered to combine sporting performance and prolonged comfort, featuring a modern structure compatible with internal cable routing, current standards, and tires up to 40 mm. This great versatility makes the bike particularly suitable for advanced endurance cycling, where smoothness, stability, and vibration absorption truly make a difference. The dedicated fork and Acros headset for integrated cables contribute to a clean aesthetic and precise, modern, and tidy handling.

The Shimano Ultegra Di2 12-speed groupset ensures fast, precise, and reliable electronic shifting in every situation. The 50/34T crankset paired with the 11-34T cassette offers a balanced gear range, ideal for tackling both fast sections and longer climbs with the right progression. Further enhancing the setup is the 4iiii Precision 3 single-side power meter integrated into the crankset, a particularly interesting solution for those who wish to monitor and optimize training with power measurement.

The Shimano Ultegra hydraulic disc braking system with 160 mm RT-CL800 Ice Tech rotors ensures power, modulation, and consistent performance even on the most demanding descents. Control remains high in every condition, increasing safety and confidence even on the longest and most technical rides.

The Bianchi Reparto Corse RC 49R carbon wheels are one of the strong points of this model. With a 49 mm profile, tubeless-ready construction, and a Ratchet system, they offer a very interesting mix of aerodynamics, stiffness, and rolling efficiency. Paired with 35 mm Pirelli P Zero Race TLR tires, they guarantee a modern and high-performance setup, capable of delivering comfort, grip, and speed even on imperfect asphalt.

Completing the picture is the integrated Bianchi Reparto Corse carbon cockpit, which gives the bike a clean look, good cable integration, and a sporty yet sustainable position. The Bianchi Infinito carbon seatpost with Countervail technology and aero-flex section, on the other hand, helps to increase vertical comfort, reducing vibrations and improving pedaling quality over long distances.

The Bianchi Infinito Pro Ultegra Di2 is therefore the ideal choice for the cyclist seeking a premium, technologically advanced endurance bike, ready to efficiently tackle training sessions, gran fondos, and long days in the saddle, with the perfect balance between comfort, performance, and technical refinement.
