Bianchi Specialissima RC Dura-Ace Di2

The Bianchi Specialissima RC Dura-Ace Di2 is a World Tour-level road bike built for riders who want elite climbing efficiency, aerodynamic speed, and uncompromising race performance in one complete package. Developed for top-level competition, the Specialissima RC reflects the demands of modern road racing, where a bike must be just as effective on steep climbs as it is on fast flats and technical descents.

At the core of the bike is an ultra-light HM carbon frame engineered to achieve a complete bike weight of just 6.6 kg (14.55 lbs). Bianchi achieved this by strategically redistributing material from the rear of the bike to the front, refining the seat stays and chain stays while optimizing the head tube for improved aerodynamic efficiency. Even small details such as the paint, derailleur hanger, and seat clamp were reconsidered to reduce weight and maximize performance.

The result is a race bike with an exceptional stiffness-to-weight ratio and measurable gains in real-world speed. Compared with the previous generation, the Specialissima RC saves 8.7 seconds on a 10 km climb at 6% gradient at 200 watts, 31.19 seconds over 40 km on flat terrain, and reduces rider effort by 3.6 watts at 30 km/h on a 6% climb. It proves that lightweight no longer has to come at the expense of aerodynamics.

Bianchi’s Reparto Corse engineering division developed the Specialissima RC as a complete system. Reparto Corse carbon wheels, integrated cockpit, saddle, and aero seatpost work together to create a bike that is cleanly integrated, highly efficient, and tuned for race-day performance. This build is equipped with a Shimano Dura-Ace Di2 12-speed groupset and power meter for precise electronic shifting, elite braking performance, and accurate ride data.

Why Can’t Light Be Aero?

The next-generation Specialissima RC answers that question with confidence. It is designed to excel on mountain roads and steep gradients without giving away speed on the flats or stability on descents. For riders who want one of the best lightweight aero road bikes available, the Specialissima RC stands at the highest level of modern race bike design.
