Colnago G4-X Shimano GRX 822 Rapid Red900 ICBL Gravel Bike

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.

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.

G4-X Features

Tyres up to 45 mm (nominal)
The G4-X can fit tyres with a maximum nominal width of 45 mm.

Handlebars solutions
The Colnago G4-X is available with either the stem + handlebar 2-piece combination or with the integrated CC.01 Wide cockpit.

Additional bottle holder
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.

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

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