Colnago G4X gravel bike Shimano GRX 820 2x12-speed Rapid Red R900 ICBL

Designed for discerning cyclists, the Colnago G4-X is a gravel bike built to perform on all terrains. Drawing on the brand’s experience in cyclocross and the V-Series (used by Team UAE), it superbly combines stability, responsiveness, lightness and terrain control.

Its monocoque carbon frame offers excellent stiffness whilst remaining agile, whilst the geometry ensures comfort for a sporty ride. The Shimano GRX 820 2x12-speed groupset offers smooth and reliable electronic shifting, suited to the demands of gravel riding.

The build is completed by high-performance Fulcrum Rapid Red 900 DB wheels, delivering a dynamic and precise ride on technical trails. With generous mudguard clearance of up to 45 mm, the G4-X is perfectly equipped for the most demanding off-road adventures.
