A balanced gravel racing bike, to perform at its best in every context.
The G4-X is the result of optimizing all those factors that are important when you have to compete or go hard on dirt roads: handling, lightness, downhill rideability, stability, frame responsiveness, and, like all Colnago bikes, surprisingly wonderful to ride.
The G4-X is the new Colnago designed for gravel racing. This model is intended to replace the G3-X, using the best of what the Cambiago-based brand has learned in its important and storied experience in off road on cyclocross and, in road racing, with the V-Series bicycles, the carbon monocoque bikes made for the UAE Emirates and UAE ADQ WorldTour Teams.
The G4-X is the product of Colnago's off-road experience, which in CX has dominated and won everything that could be won. Some of the brand's most notable victories include those of Sven Nys, winner of six CX World Championships, and Wout Van Aert, who won two off-road World Championships with Colnago.
The concept of the G4-X is derived directly from the V4Rs, the bicycle that the UAE Emirates team and the UAE ADQ team use in the WorldTour. The two models share the design spirit and the aesthetical look. V4Rs was designed to be the perfect point of balance of everything that a professional rider needs. The same is true for the G4-X: the optimal balance of those features requested to win races on the dirt roads
PERFECT BALANCE OF ELEMENTS
It is easy to tell a bicycle by one specific number: the most aero, the stiffest, the lightest... Yet in the end, it is not one number that makes the pedaling experience. The riding experience is the result of the perfect balance of many factors, and it is this balance that we focused on to design our fast gravel bike.
The G4-X is the result of optimizing all those factors that are important when you have to compete or go hard on dirt roads:
- Handling
- Lightness
- Robustness
- Aerodynamics
- Stability
- Frame responsiveness
TIRE CLEARANCE
The nominal tire clearance of the G4-X has increased from 40 to 45 mm compared with the previous model. The Colnago G4-X is available either with standard two-piece stem+handlebar combination or with Colnago's Integrated CC.01 Carbon Cockpit, Wide version as standard but the road one is compatible as well. Since it has a regular 1 1/8 inch fork steerer tube, spread compatibility with third-party solutions is guaranteed.
INTEGRATED HANDLEBAR SOLUTION - CC.01 WIDE
The Colnago CC.01 Wide has more flare than its road counterpart, the Colnago CC.01, with 3cm for each side instead of 1cm. Like the basic version, it is a carbon monocoque, which allows for both significant weight savings and increased bike stiffness. The reach is 72.50 mm and has a drop of 120 mm. The stem angle at the handlebar is 82 degrees.
MOUNTING POINTS
The G4-X features features four riveted mounting points, two on the standard bottle cages location on the main triangle, plus one facing down on the down tube and one on the top tube. The Colnago G4-X can mount any type of electronic, both single and double chainring. In addition, it is compatible with UDH, a new universal rear derailleur hanger designed by SRAM.
