Colnago V4Rs Dura Ace Di2 Road Bike The Colnago V4Rs shares many similarities with its predecessor, the V3Rs, but it has undergone enhancements in aerodynamic performance and slight weight reduction. Through rigorous testing in various configurations, including wind tunnel trials and real-world scenarios, the V4Rs achieves an optimal blend of ride comfort and stiffness. Notably, stiffness has been marginally reduced in the head tube while remaining consistent in the bottom bracket area, resulting in improved stability and solidity. The updated carbon structure exhibits greater flexibility and resilience overall. Consistency in stack-reach ratios across sizes ensures consistent handling and a sporty feel across the frame spectrum. Engineered for racing, the aggressive yet comfortable geometry ensures performance even during prolonged rides. Featuring a CeramicSpeed SLT headset, the frameset mitigates contamination and corrosion risks. When paired with the separately available CC.01 bar, a fully integrated system is realized. Initially designed for the V4Rs and later introduced on the C68 model, Colnago asserts a 16% reduction in drag with this combination, without compromising stiffness compared to traditional round bars. Nonetheless, the frameset remains compatible with conventional handlebars if desired. Accommodating tires up to 32mm wide caters to riders seeking heightened comfort alongside performance, and the frameset exclusively supports electronic groupsets. A color-matched carbon aero seatpost adds a sleek finishing touch to the ensemble.
