Shimano RX825 Di2 2×12

Engineered for performance on mixed terrain, the Colnago G4X 2x Carbon Gravel Bike pairs Italian racing heritage with modern gravel-ready tech. With a carbon frame designed for control and comfort across gravel, dirt and tarmac, this complete bike features Shimano’s latest RX825 Di2 2×12 electronic gravel groupset for precise shifting and reliable braking wherever the ride leads.

Built around the purpose-designed Colnago G4-X carbon fork and frame, the G4X offers optimal stiffness, low weight and confident handling on demanding off-road adventures.
