The CX-1 represents the top of the line monocoque frames from Colnago, the front triangle is a monocoque structure where the seat and chain stays are lugged to the frame, this to improve the handling of the CX-1. Expect the ride of the CX-1 to be fast, aggressive especially on climbs and sprints you will feel the CX-1 performing with no loss of power transfer or handling.
The polygonal shape of the top and down tube of the CX-1 does increase the lateral stiffness so no loss of power is experienced. The lugged seat and chain stays are designed to give the rider maximum control and power transfer during a descent, sprint, climb and breaking.
