The perfect balance of the elements.

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.

*Please note that the product images shown may feature a different component configuration from the actual build offered for sale. Refer to the listed specifications for accurate details.

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.

The G4-X can fit tires with a maximum nominal width of 45mm.

The Colnago G4-X is available with either a two-piece stem and handlebar setup or the integrated CC.01 Wide cockpit. Please note: the CC.01 is not included in the Shimano GRX 822 1x build but is available as a separate order.

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 bottle cages or small bags.


The G4-X will be mounted with the standard T47 bottom bracket

There is a new seatpost clamp, designed to withstand more tightening torque and guarantee stability and safety during intense off-road riding.
