Colnago G3X Shimano GRX 820 2 x 12V

From cyclocross to gravel. Fast on any terrain.

The Colnago racing soul triumphs on dirt roads. The G3-X is the gravel bike for tackling any type of terrain in any season, designed for riding on dirt and muddy terrain, comfortable even over long distances The G3-X is made with a carbon monocoque frame and is designed to be fitted with disc brakes; the chain stays are wide enough to fit tyres up to a maximum of 40 millimetres.

Features

• The G3-X is equipped with two protective plastic mudguards: one under the bottom bracket and one above the right chain stay to protect the chain from blows
• For longer adventures it may be necessary to add bags and bottle cages. This is why the G3-X is equipped with two rivets on the top tube and two under the down tube
• The grommet, usually a bolt-on plastic component, is now moulded to make it even lighter and offer the best shifting performance
