V4 Ultegra Di2
The Colnago V4 distills the racing DNA of the V4Rs into a more accessible all-rounder without sacrificing the precision or elegance the brand is known for. Built around a monocoque carbon frame that shares the same carbon layup research and aerodynamic studies as its race-bred sibling, it delivers a stiff, reactive ride that feels at home on climbs and rolling terrain alike. The fully integrated one-piece cockpit routes every cable internally for a clean, purposeful aesthetic that is unmistakably Colnago. The V4 brings electronic shifting performance to a price point that opens the door to serious riding.

Why we like the Colnago V4 Ultegra Di2
Race Pedigree in a Road-Ready Package
The V4 uses the same carbon layup research and aerodynamic geometry principles as the flagship V4Rs. You get a noticeably stiffer, more responsive chassis than typical bikes at this price, with a shortened head tube and lengthened fork that keeps it agile on climbs and precise through technical sections.
Clean Integration
The CC.01 one-piece carbon cockpit routes every cable internally through the stem and fork, leaving the front end completely uncluttered. This is not just aesthetic: it reduces flex at the bars and shaves meaningful grams compared to a traditional separate stem and bar setup.
Thoughtful Spec for the Price
Vision SC 45 carbon wheels paired with an electronic groupset represent exceptional value at this tier. Both Ultegra and 105 Di2 builds use the same shift logic and battery architecture, so the ride experience is consistent regardless of which build you choose.
