Colnago G4-X | Shimano GRX820 2x: The New Standard in Gravel Racing

The Colnago G4-X is more than just a gravel bike; it is the pinnacle of Colnago’s competitive off-road evolution. Replacing the successful G3-X, the G4-X integrates the legendary cyclocross heritage—proven by World Champions like Wout Van Aert and Sven Nys—with the high-performance carbon monocoque engineering of the V4Rs series used by UAE Team Emirates.

The Perfect Balance of Performance

In the world of gravel racing, victory isn't determined by a single metric. The G4-X was developed under the philosophy of "Perfect Balance." Colnago’s engineers have meticulously harmonized weight, stiffness, and handling to create a bike that feels as responsive on technical dirt climbs as it does stable on high-speed gravel descents.

Key Features
