Bianchi Specialisma RC Dura Ace Road Bike
The Bianchi Specialissima is a mountain conquering marvel that seamlessly combines aerodynamic prowess with world-class stiffness-to-weight ratio. Crafted with precision engineering by the racing division, Reparto Corse, this bike redefines performance on steep gradients, shifting the threshold to a mere 6.2%. Every part of the Specialissima was optimized, offering an efficient system that brings rider and machine together.
Compared to the previous generation, the new Specialissima saves riders 8.7 seconds on a 10 km climb at 6% grade when exerting 200 watts. On flat terrains, it shaves off 31.19 seconds at the same wattage. For elite climbers maintaining 30 km/h on a 6% gradient, the Specialissima reduces effort by 3.6 watts.
Weighing in at just 6.6 kg (+/- 5% variation), this bike achieves its aerodynamic advantages without sacrificing weight. A strategic redistribution of materials from the rear to the front, with super-fine seat stays and thinner chain stays, enhances its aerodynamic front-end. Even the paint scheme on the RC models is designed to be lightweight, tipping the scales 40 g lighter than other colorways. Expert painters at Bianchi used blended gradient transitions, accentuated by iridescent paints and matte finishes, creating a sense of airiness. The result is a modern interpretation of Bianchi's signature CK16, featuring hues of purple and gray, combined with a contemporary take on celeste, the brand's soul.
The Bianchi Specialissima is your key to conquering the mountains with unparalleled efficiency and style.
