Gravel COLNAGO G3-X

The Ultimate Gravel Adventure

The Colnago G3-X is a high-performance gravel bike equipped with a complete Shimano GRX groupset. Built for speed, versatility, and adventure, it is the fastest gravel bike Colnago has ever designed.

Whether you’re exploring scenic backroads or pushing your limits on rugged trails, the G3-X is your most reliable companion. Endorsed by Nathan Haas, it combines Colnago’s racing heritage with the ultimate gravel functionality.

Like the Basso Palta and the Cinelli King Zydeco, the G3-X is a gravel bike that can go anywhere, while being slightly less road-oriented than the Wilier Rave.

Technical Highlights

Bottom Bracket

The G3-X uses Colnago’s proven ThreadFit82.5 system, essentially a PressFit with removable base sleeves. The bottom bracket lug has been refined for maximum performance. The integrated cable guide replaces the traditional bolt-on plastic part, reducing weight while offering the largest possible radius for smoother, precise shifting.

Seatpost

Inspired by the V3Rs seatpost, the semi-truncated aero shape improves aerodynamic performance while offering better vertical compliance than the previous 31.6 mm round seatpost. It delivers comfort and control on long gravel adventures.

Campagnolo Ekar

The gravel-focused Campagnolo Ekar groupset was born for the challenges of Italian gravel. Just as legendary climbs inspire performance, Ekar embodies adventure, freedom, and the spirit of gravel riding.

SRAM Rival eTap AXS

Modern riders can enjoy intuitive wireless shifting, innovative gearing, integrated power measurement, AXS connectivity, and refined hydraulic disc brakes. SRAM Rival eTap AXS combines simplicity with advanced performance.
