Description
The Colnago G4-X with Shimano GRX RX717 Di2 is a gravel bike for riders who want to keep up the pace on unpaved roads, with electronic shifting. This build runs on aluminium wheels by Fulcrum, is ice blue and comes in size 45, for a rider height of 155 to 167 cm. The frame of the G4-X is monocoque carbon and made to be ridden hard on gravel: light on climbs, stable on loose ground and composed on descents. There is room for tyres up to 42 mm and there are four mounting points for bottle cages or small bags. GRX RX717 Di2 shifts electronically across 1x12 gears, with no front derailleur. Handlebar and stem are separate parts, so length and width are easy to change later. This bike is factory-new and unridden. Colnago gives a two-year manufacturer’s warranty on the frame, plus a third year if you register the bike with Colnago within ten days of purchase. A Colnago bottle cage is included, pedals are not.
