Colnago V4 105 Di2 Vision SC45 Road Bike

Lightness and responsiveness, with Colnago charm

The Colnago V4 is an all-around 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 realisation 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.

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