With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

Season:2026Sale

Brand:Colnago

Code:KDDV54CS.21.2ID.CSID.4V.5

The Colnago V4 is an all-round carbon road bike with a racing character, combining a stiff, solid and responsive monocoque frame with the carbon development and aerodynamic research that went into the V4Rs. Its refined design is built to deliver an engaging ride across fast road riding and racing.

The front of the frame draws on the aerodynamic characteristics of the V4Rs, with a sleek head tube and revised fork designed to improve airflow, particularly during fast technical descents. The frame accommodates tyres up to 30mm and uses integrated cable routing through the Colnago cockpit and fork for a clean, streamlined appearance.

This build combines Shimano Ultegra Di2 12-speed electronic shifting with hydraulic disc brakes, a 52/36T chainset and 11-34T cassette. Vision SC45 carbon wheels and Pirelli P7 Sport 28mm tyres complete the package, providing a fast, responsive setup for performance road riding.
