COLNAGO G4-X BIKE SHIMANO GRX 827 DI2 VISION SC45

A balanced gravel racing bike, to give its best on any terrain
The G4-X is the result of optimizing all those factors that are important when racing or going fast on gravel roads: handling, light weight, downhill ability, stability, frame responsiveness and, like all Colnago bikes, surprisingly wonderful to ride. The G4-X can fit tires up to 45 mm wide. For longer adventures you may need to add bags and bottle cages. For this reason, the G4-X is equipped with four mounting points for bottle cages or small bags. There is a new seatpost clamp, designed to withstand greater tightening torque and ensure a secure fit during the most intense off-road rides. The perfect harmony of the elements, a balanced gravel bike. The Colnago G4-X is a bike that demands to be pedaled fast, but without sacrificing handling and riding pleasure.
