Colnago V4 Shimano 105 Di2 Racing 800 DB - Red

The Colnago V4 105 Di2 Racing 800 DB Road Bicycle is built for riders who want a fast, lively and rewarding ride across a wide range of road conditions. It carries the balanced character of an all-round race bike, making it equally enjoyable on climbs, rolling roads and faster flat sections.

Responsive Monocoque Frame: At the heart of the bike is a monocoque carbon frame that feels stiff, solid and reactive under effort. Developed with the benefit of the same carbon layup research and aerodynamic studies that shaped the V4Rs, it delivers a refined ride feel with true Colnago character.

Geometry with a Racing Edge: With a shorter head tube and longer fork than previous models, the V4 is designed to improve rideability while sharpening responsiveness. This updated geometry gives the bike a more confident and capable feel, especially for riders who enjoy a precise front end and a sportier road position.

Balanced for Real-World Speed: Quality carbon construction and performance-focused fittings help the V4 maintain an excellent balance between handling, efficiency and overall ride quality. Its light structure and aerodynamic detailing make it a strong choice for riders looking for speed without sacrificing control or versatility.
