Vélo gravel Colnago G4X Shimano GRX 820 2x12v Fulcrum Lite ER PIGR

Designed for gravel cyclists seeking performance and versatility, the Colnago G4X combines the Italian brand’s racing heritage with a modern design capable of adapting to all terrains. Inspired by the cyclocross bikes developed by Colnago and the experience gained at the very highest level, it offers an excellent balance between responsiveness, handling precision and comfort over long distances.

Its monocoque carbon frame stands out for its lightness and stiffness, whilst maintaining a stable and efficient geometry for fast riding on both roads and technical trails. Paired with the GRX 822 2x12-speed Shimano drivetrain, it ensures fast and reliable gear changes in all conditions.

This build is fitted with Fulcrum Lite ER wheels, renowned for their versatility and reliable performance across varied terrain. They offer good responsiveness and excellent stability, allowing you to make the most of the G4X’s capabilities, particularly with tyres up to 45 mm wide to enhance grip and comfort on the most demanding routes.
