Frameset Purchase: This is a frameset purchase, not a complete bike. Included components are the frame, fork, headset, seatpost, and finishing kit. Drivetrain, wheels, brakes, cockpit, and all other components are sold separately. Product photos show a complete build for illustrative purposes.

The Colnago G4-X is a purpose-built gravel race frameset that balances the competing demands of competitive off-road riding: handling precision, frame stiffness, downhill stability, and the lightness to climb without compromise. This is the frameset for riders who know how they want to ride and want to build around a frame that earns its place on a gravel start line.

Need to Know

KEY FEATURES

Monocoque Carbon Frame: A single-piece carbon construction that provides excellent stiffness, responsiveness, and consistency across all frame sizes - built for riders who compete or push hard on mixed terrain.
Carbon Disc-Specific Fork: Designed specifically for flat-mount disc brakes with a round-section crown, optimised for the steering precision and compliance that technical gravel demands.
45mm Tire Clearance: Room for serious gravel rubber up to 45mm nominal width, opening up the full spectrum of terrain from fast gravel roads to rough backcountry tracks.
T47 Bottom Bracket Shell: A threaded T47 interface provides a reliable, creak-free foundation compatible with a wide range of modern gravel groupsets.
Four Bottle Cage and Bag Mounting Points: Built-in mounts for cages and frame bags mean the G4-X is ready for long days and bikepacking setups without aftermarket adapters.
Flexible Cockpit Compatibility: The G4-X works with either a traditional stem and handlebar setup or the Colnago CC.01 Wide integrated one-piece cockpit, giving you full control over your fit and front-end feel.

PERFECT FOR

Riders who want to build a bespoke gravel race machine around a proven Italian carbon platform, with the flexibility to spec their own groupset, wheels, and cockpit.

Why we like the Colnago G4-X Frameset

Build It Your Way

The G4-X is compatible with a wide range of modern gravel groupsets and wheel standards, giving you the freedom to build exactly the bike you want. Whether you're pairing it with a flagship electronic groupset and carbon race wheels or speccing it with a reliable mechanical drivetrain and durable alloy wheels, the frame supports your vision without compromise.

45mm Clearance, No Excuses

Genuine 45mm tire clearance means the G4-X can run the volume of rubber that modern gravel racing demands. Whether you're on a course that transitions from fast gravel to technical singletrack, or building a frame that doubles as an adventure bike, the clearance is there to support it.

Four Mounting Points is Quietly Significant

Most gravel frames offer two cage mounts. The G4-X has four, giving you the flexibility to run two cages, add a frame bag, or set up for multi-day riding without compromise. For riders who cover remote terrain or enter events with long unsupported sections, that extra mount has real practical value.

Colnago is an Italian bicycle manufacturer founded in 1954 by Ernesto Colnago in Cambiago, near Milan. What began as a small workshop driven by an obsessive passion for cycling quickly grew into one of the most revered names in the sport. For over 70 years, Colnago has stood at the intersection of Italian artistry and engineering excellence, producing road bikes that represent the pinnacle of two-wheeled craftsmanship. From the iconic lugged steel frames of the Master era to the hand-laid carbon of the modern C68 and C72, every Colnago bicycle reflects the brand's unwavering commitment to quality. Recognized by the distinctive Asso di Fiori (Ace of Clubs) logo, Colnago bikes have graced the peloton's greatest stages and the most demanding roads in the world, and continue to define what it means to ride Italian.
