ALL COLNAGO BIKES ARE BUILT TO ORDER – PLEASE CONTACT US TO DISCUSS YOUR BUILD AND CHECK THE LATEST LEAD TIMES BEFORE PLACING AN ORDER. IMAGES ARE FOR ILLUSTRATION PURPOSES ONLY.
The Colnago G4-X is built for riders who demand uncompromising performance on gravel, cyclocross, and everything in between. Handmade with Colnago’s advanced carbon construction, the G4-X blends race-level stiffness with confident handling and refined ride comfort, delivering a platform that feels precise, planted, and ready for the fast line.
The updated frame optimises tyre clearance, stiffness-to-weight, and vibration diffusion, giving the G4-X the capability to excel across technical terrain, high-speed gravel, and race-intensity efforts. A balanced geometry promotes confident cornering, sharp response, and long-haul efficiency, while the integrated cockpit and internal cable routing keep the entire bike clean and aerodynamic.
Paired with Shimano’s latest GRX Di2 12-speed, the G4-X gains ultra-reliable shifting performance designed specifically for the demands of fast gravel. Wide gear range, powerful braking, and the precision of fully electronic shifting make it a drivetrain that thrives under pressure.
Whether you're taking on the biggest UK gravel events, racing CX, or building a high-performance all-terrain machine, the G4-X stands out as Colnago's purest expression of off-road racing DNA.
