gravel bike mtb frame Colnago G4-X SRAM Force XPLR 1x13 | Vision SC45

gravel bike mtb frame Colnago G4-X SRAM Force XPLR 1x13 | Vision SC45The G4 X is the new Colnago designed for gravel racing. This model replaces the G3 X, using the best of what the Cambiago based brand has learned from its extensive off road experience in cyclocross and, in road racing, with the V Series bicycles the carbon monocoque machines made for the UAE Emirates and UAE ADQ WorldTour Teams. The G4 X is the culmination of Colnagos off road heritage, which in cyclocross has dominated and won everything possible.

The G4-X is the new Colnago designed for gravel racing. This model replaces the G3-X, using the best of what the Cambiago-based brand has learned from its extensive off-road experience in cyclocross and, in road racing, with the V-Series bicycles — the carbon monocoque machines made for the UAE Emirates and UAE ADQ WorldTour Teams.

The G4-X is the culmination of Colnago’s off-road heritage, which in cyclocross has dominated and won everything possible. 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 riding Colnago frames.

The concept of the G4-X is directly derived from the V4Rs, the bicycle used by the UAE Emirates and UAE ADQ teams in the WorldTour. The two models share the same design philosophy and aesthetic identity. The V4Rs was created as the perfect balance of everything a professional rider needs — and the same is true for the G4-X: the optimal harmony of all characteristics required to win on dirt roads.

Perfect Balance of Elements
It's easy to define a bicycle by a single number — the most aerodynamic, the stiffest, the lightest… Yet, in the end, no single number defines the riding experience.

The G4-X is the result of optimizing all the essential factors that matter when racing or pushing hard on gravel:

• Handling
• Lightness
• Robustness
• Aerodynamics
• Stability
• Frame responsiveness
• Tire clearance

The nominal tire clearance has increased from 40 mm (previous G3-X) to 45 mm. The G4-X is available with a standard two-piece stem + handlebar setup or with Colnago’s Integrated CC.01 Carbon Cockpit (Wide version as standard), while the road version is also compatible.
Since the fork steerer tube is a traditional 1 1/8”, the frame remains widely compatible with third-party solutions.

Integrated Handlebar Solution — CC.01 Wide
The Colnago CC.01 Wide offers greater flare than its road counterpart — 3 cm per side instead of 1 cm. Like the standard version, it is a carbon monocoque, delivering considerable weight savings and improved stiffness.

It features a 72.5 mm reach, 120 mm drop, and an 82° stem-to-bar angle.

Mounting Points
The G4-X features four riveted mounting points: two in the traditional bottle cage positions inside the front triangle, one under the down tube, and one on the top tube.

The frame supports any electronic groupset, whether single or double chainring, and is compatible with UDH — the universal derailleur hanger standard developed by SRAM.
