A balanced serious racing bike, to give the best of itself on every terrain.
The G4-X is the result of optimization of all those factors that are important when you have to compete or go strong on dirt roads: handling, lightness, driving down, stability, frame responsiveness and, like all Colnago bikes, surprisingly wonderful to drive.
