The Colnago CX1 Evo 2011 Road Bike Frameset is the same immensely popular carbon monocoque frame that has won stages at the Giro D'Italia and the Paris-Nice but with a brand new look for the upcoming season. While it retains all its mechanical features, it introduces internal cable routing for the rear brake. Colnago's pro teams have been blown away by the CX-1 Evo's quality and ride performance, combining the rigidity needed for maximum power transfer when sprinting or climbing with rock-steady handling. At the heart of this winning combination is the CX-1 Evo's monocoque front triangle, which is moulded in one piece, in the alfa carbon blend, combined with computer designed polygonal cross section tubes entirely designed with the aid of CAD and finite element analyses. Available in eight sizes to ensure an exact fit, the CX-1 guarantees a thrill every time you ride.
There is no one perfect material for a bicycle frame. All have advantages and disadvantages. A very strong material might be very light, but fatigue too quickly for the repeated stresses of cycling. Or it might be simply too expensive for some riders' budget. At Colnago they use a range of materials to balance these factors. The immense strength and versatility of carbon fibre has made it the most popular material for top-quality road racing bicycles. Colnago use Toraya carbon fibre in a variety of grades and types according to the specific requirements of the frame or component. Their one-piece monocoque frames us pre-preg carbon cloth, laser-aligned in a mould and heated under pressure to form a seamless, strong, light unit.
