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.

KEY FEATURES

Race-Proven Monocoque Carbon Frame: Shares aerodynamic and carbon layup R&D with the V4Rs, delivering a stiff, reactive ride that punches well above its price point.
Colnago CC.01 Integrated Carbon Cockpit: The one-piece handlebar and stem routes cables fully internally, improving front-end stiffness and eliminating clutter from the front end.
Electronic Shifting Platform: Shimano Ultegra 12-speed drivetrain provides precise, consistent shifts at the touch of a button in any conditions.
Vision SC 45 Carbon Wheelset: A 45mm rim depth with 21mm internal width strikes a compelling balance between aerodynamic efficiency and road feel.
Tire Clearance to 32mm: The disc-specific fork with concave chainstays handles up to 32mm nominal tires, adding versatility for rough roads and longer days in the saddle.
Full Hydraulic Disc Braking: Shimano Ultegra BR-R8170 calipers with asymmetric 160/140mm rotors provide powerful, well-modulated stopping in any weather.

PERFECT FOR

Ambitious road riders who want a race-caliber Italian carbon bike with modern geometry, electronic shifting, and a refined aesthetic, without stepping all the way up to the V4Rs price point.

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.

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.

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.

Colnago is an Italian bicycle manufacturer founded in 1954 by Ernesto Colnago in Cambiago, near Milan. What began as a small workshop driven by an obsessive passion for cycling quickly grew into one of the most revered names in the sport. For over 70 years, Colnago has stood at the intersection of Italian artistry and engineering excellence, producing road bikes that represent the pinnacle of two-wheeled craftsmanship. From the iconic lugged steel frames of the Master era to the hand-laid carbon of the modern C68 and C72, every Colnago bicycle reflects the brand's unwavering commitment to quality. Recognized by the distinctive Asso di Fiori (Ace of Clubs) logo, Colnago bikes have graced the peloton's greatest stages and the most demanding roads in the world, and continue to define what it means to ride Italian.
