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. The G4-X can fit tires with a maximum nominal width of 45mm. For longer adventures it may be necessary to add bags and bottle cages. This is why the G4-X is equipped with four mounting points for bottlecages or small bags. There is a new seatpost lock, designed to withstand more tightening torque and guarantee stability and safety during intense off-road riding. The perfect harmony of the elements, a balanced gravel bike. Colnago G4-X is a bike that demands to be pedaled fast, without sacrificing handling and riding pleasure.
