Colnago V4Rs Ultegra Di2 Road Bike
The Colnago V4Rs Ultegra Di2 Road Bike, an evolution of its predecessor, the V3Rs, boasts improved aerodynamics and a slight reduction in weight. Extensively tested across different configurations, including wind tunnel assessments and real-world trials, it strikes an impeccable balance between ride comfort and stiffness. Noteworthy adjustments include a slight decrease in stiffness at the head tube, enhancing stability, while maintaining consistent stiffness at the bottom bracket, ensuring solid handling.
