Manufactures Description
A balanced gravel racing bike, to perform at its best in every context. The G4-X is the result of optimizing all those factors that are important when you have to compete or go hard on dirt roads: handling, lightness, downhill rideability, stability, frame responsiveness, and, like all Colnago bikes, surprisingly wonderful to ride.
