Lightness and responsiveness, with Colnago charm

The Colnago V4 is an all-round bicycle, a bike that is extremely fun to ride and has a clean and refined design. The frame is a monocoque which is stiff, solid, reactive, and which enjoys the same carbon layup R&D and aerodynamic studies that led to the realization of the V4Rs. Quality carbon and fittings designed to offer an excellent level of performance make the V4 a perfectly balanced bike in every respect. The design combines technical features with light and aerodynamic details.

Steering tube
Shorter head tube and longer fork than previous models for enhanced rideability and responsiveness. These features - combined with quality carbon - make this bike perfectly suited to both climbs and flatter terrain.

Fork
The fork is designed specifically for disc brakes and has concave chain stays to accommodate tyres up to 30mm (nominal).

Wiring
The cables run inside the Colnago SR10 stem and then through the fork stem. This makes for an extremely sleek and technically more aerodynamic frame.
