Pre-Order

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

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Season:2026Sale

Brand:Colnago

Code:V4ULTDI420VDRD

The Colnago V4 is an all-round carbon road bike with a racing character, combining a stiff, solid and responsive monocoque frame with development and aerodynamic research derived from the V4Rs. Its clean, refined design delivers an engaging platform for fast road riding and racing.

The front of the V4 takes aerodynamic cues from the V4Rs, with a sleek head tube and revised fork designed to improve airflow, particularly during fast technical descents. With clearance for tyres up to 30mm, the V4 balances aerodynamic performance with practical road-riding versatility.

This build features Shimano Ultegra Di2 12-speed electronic shifting, a 52/36T chainset and 11-34T cassette, combined with hydraulic disc brakes and Fulcrum Racing 600 DB wheels. Pirelli P7 Sport 28mm tyres complete the performance-focused package.

Key Features & Benefits:

  • Responsive Carbon Frameset: The V4's carbon monocoque construction combines stiffness, solidity and responsiveness with aerodynamic development derived from the V4Rs.
  • Shimano Ultegra Di2: The 12-speed electronic groupset delivers precise shifting across a 52/36T chainset and wide-range 11-34T cassette.
  • Race-Ready Wheel and Tyre Package: Fulcrum Racing 600 DB wheels and 28mm Pirelli P7 Sport tyres provide a balanced combination of speed, control and everyday road performance.
