COLNAGO G4X GRX 822 RAPID RED 500 BIKE

A well-balanced gravel racing bike, built to perform at its best on any terrain.
The G4-X is the result of optimizing all the elements that matter when racing or riding fast on dirt roads: handling, lightness, downhill control, stability, frame responsiveness and, as with all Colnago bikes, an incredibly enjoyable ride. The G4-X can accommodate tires up to 45 mm wide. For longer adventures, extra storage might be needed, so the G4-X features four mounting points for water bottles or small bags. A new seatpost clamp has been designed to withstand greater torque and ensure a secure fit during intense off-road racing. The perfect harmony of elements — a balanced gravel bike. The Colnago G4-X is made to be ridden fast without sacrificing handling or ride enjoyment.

The Colnago G4-X Shimano GRX 822 1x is a bike designed to deliver outstanding performance on dirt roads and in gravel races. With a carbon frame, Shimano GRX 1x drivetrain, and high-quality components, this bike offers reactivity, comfort, and stability, making it your ideal companion for gravel adventures.

Its versatility, combined with meticulous engineering, lets you tackle any kind of terrain — from white roads to technical descents — with confidence, making every training session or race an unforgettable experience.
