The Bianchi Impulso Reparto Corse GRX825 Di2 2026 is a purebred gravel race machine developed for riders chasing maximum speed, efficiency, and control across modern gravel terrain. Built around Bianchi’s high-modulus HM-HS carbon platform and refined through Reparto Corse racing development, the Impulso RC delivers an aggressive yet stable ride designed specifically for high-speed gravel competition and endurance performance.

Unlike adventure-focused gravel bikes, the Impulso RC is engineered with racing at its core. The progressive geometry combines a longer reach, short stem, and stable wheelbase to deliver exceptional confidence on technical descents while maintaining sharp responsiveness during accelerations and high-speed sections. Integrated cable routing and the Reparto Corse AeroFlare cockpit enhance aerodynamics while keeping the front end clean and race-ready.

Equipped with Shimano’s latest GRX825 Di2 2x12-speed electronic groupset, the Impulso RC provides fast, precise shifting with outstanding drivetrain reliability in all conditions. The 48/31T crankset paired with an 11–36T cassette gives an excellent balance between top-end speed and climbing capability, making it equally suited to gravel racing, mixed-surface riding, and long-distance events.

One of the standout features is the Reparto Corse RC43 carbon wheelset. With a 43mm aero profile and wide 25mm internal width, these wheels are designed to maximise speed, stability, and tyre support for modern gravel racing. Combined with Pirelli Cinturato Gravel RC tyres, the bike delivers excellent traction, lower rolling resistance, and impressive comfort on rough terrain.

At approximately 8.1kg (+/-5%), the Impulso RC sits among the most performance-focused gravel bikes in the category, offering elite-level speed with unmistakable Italian styling and race pedigree.
