The Colnago G4-X Frameset is engineered for riders seeking elite gravel performance rooted in Colnago’s racing heritage. Built from high-grade carbon fiber and shaped for stability and precision on fast, technical terrain, the G4-X blends race-ready responsiveness with the durability demanded by modern gravel riding.

The frame’s carbon layup balances stiffness and compliance, giving the bike efficient power transfer while smoothing vibrations over rough surfaces. Its geometry is tuned for aggressive riding—quick in tight sections, controlled on descents and balanced during long efforts. Ample tire clearance allows riders to run wider gravel tires for added comfort and traction across varied terrain.

The G4-X incorporates clean internal routing, a tapered head tube and reliable flat-mount disc-brake compatibility for consistent stopping power. The frameset is built to accommodate a wide range of drivetrain setups, making it a versatile foundation for competitive gravel racing or high-performance adventure builds.
