The G4-X is the new Colnago designed for gravel racing. This model replaces the G3-X, drawing from Colnago’s extensive experience in off-road riding through cyclocross and from the V-Series road bikes — the carbon monocoque frames engineered for the UAE Emirates and UAE ADQ WorldTour teams.

The G4-X is deeply rooted in Colnago’s off-road legacy. In cyclocross, the brand has achieved unmatched dominance, securing countless victories. Among the most notable are Sven Nys’ six Cyclocross World Championships and Wout Van Aert’s two World Championship titles earned aboard Colnago bikes.

The design philosophy of the G4-X comes directly from the V4Rs — the bike used in the WorldTour by UAE Emirates and UAE ADQ. Both models share the same performance-driven engineering approach. The V4Rs was created as the perfect balance of everything a professional rider requires. The same principle guided the G4-X: achieving the ideal equilibrium of performance factors essential for winning on gravel terrain.

Perfect Balance of Elements
A great bicycle cannot be defined by a single number — aerodynamics, stiffness, weight… The riding experience is shaped by the balance of many factors. This harmony is what Colnago prioritized in the development of its fastest gravel racing bike.

The G4-X optimizes all key characteristics for competing and pushing hard on dirt roads:

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

The nominal tire clearance has been increased from 40 mm (G3-X) to 45 mm. The G4-X can be equipped with a traditional two-piece stem and handlebar, or with Colnago’s Integrated CC.01 Carbon Cockpit in the Wide version (standard). The road version of the CC.01 is also compatible.
Thanks to the classic 1 1/8” fork steerer tube, the G4-X maintains wide compatibility with third-party cockpit setups.

Mounting Points
The G4-X includes four riveted mounting points: two standard bottle cage mounts inside the main triangle, one under the down tube, and one on the top tube.

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

Great Sunscreen at a Great Price!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Love this sunscreen. I live in FL and like to walk most mornings, and need a good sunblock. This Amazon Basics is far better than my previous, far more expensive brand. It's a great price for great quality. I've been using it on my body & face, it's non-greasy, absorbs well, and really seems to offer very good sun protection. And I really appreciate the next day shipping on my past two orders, Amazon. Thanks for the great product & great service!

Works when working outside and heavy activities
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I use it as an Amazon delivery driver, and it works in the heat and sweat is no issue it does last for 2 hours. Reapplying it is extremely easy, no burns or sun damage to my skin. I can tell you it works cause I’m recovering from skin cancer and it works no problems or anything.

Just ok - too thick to apply evenly
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Just ok - very thick, so difficult to apply evenly. I use this for outdoor cycling and it works, but it's so thick that it tends to clump instead of smoothly covering the skin.

Excellent mineral sunscreen for sensitive skin.
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
I’ve been using the Blue Lizard Sensitive Mineral Sunscreen, and it’s become a staple in my routine. As someone with sensitive skin, I really appreciate that it’s fragrance-free and uses zinc oxide, providing great protection without causing any irritation or breakouts. It goes on smoothly, isn't overly greasy, and the water resistance holds up well for outdoor activities. The smart cap technology is a nice touch, too. Highly recommended if you’re looking for effective, non-irritating sun protection.
