The Cx Zero EVO is the bike for endurance. A professional level racing frame, proven in the Spring Classics in Europe, the CX Zero Evo strikes a perfect balance between performance and comfort. The most versatile Colnago model, the CX Zero Evo has been developed to meet the demands of cycling in the greatest range of conditions. “Classic” geometry for fit combines a taller head tube and slightly shorter top tube. This allows a more relaxed position of the shoulders and arms and a more open angle between the torso and thigh for more efficient pedaling during even the longest days in the saddle. The tube shapes of the rear triangle are designed to offer maximum vertical compliance while allowing clearance for up to 25mm tires. The seatpost is a smaller 27.2mm diameter. All of these features promise more rider comfort and less fatigue. Your last mile will be as enjoyable as your first on the CX Zero Evo, on the most epic rides and on the most challenging roads. Eight sizes available: 42s , 45s , 48s , 50s , 52s , 54s , 56s and 58s , all sloping.
