Description
Colnago V4 Ultegra Di2 Road Bike
The Colnago V4 Ultegra Di2 Road Bike is a true all-rounder, designed for riders who value performance, style and versatility. With its clean, refined aesthetic and lively ride character, it delivers a balance of speed, responsiveness and comfort that makes every ride enjoyable.
The monocoque carbon frame is stiff, solid and reactive, benefitting from the same carbon layup research and aerodynamic development used in the creation of the flagship V4Rs. Paired with a Shimano Ultegra Di2 electronic groupset, the V4 offers smooth, precise shifting and a premium riding experience suited to everything from fast group rides to long solo efforts.
