**PLEASE REFER TO BUILD SPEC BELOW, IMAGE FOR REFERENCE**
A balanced gravel racing bike, to perform at its best in every context.
The G4-X is the result of optimizing all those factors that are important when you have to compete or go hard on dirt roads: handling, lightness, downhill rideability, stability, frame responsiveness, and, like all Colnago bikes, surprisingly wonderful to ride.
Please note that the specifications supplied by the manufacturer may be impacted by component stock availability at the factory assembly stage.
