Built to win

Please note: The bikes are assembled according to the manufacturer's specifications with default features according to size. For any assembly requests or specifications other than the basic ones, please contact our costumer service directly before purchase.

This bicycle has been engineered and built to do just one thing: win. The Colnago V4Rs is the results of years of research and tests in the World Tour. Improved stiffness, better aerodynamics, weight decrease. A winning bicycle must be stiff, light, aerodynamic, comfortable and robust. The V4Rs is today's best bike by mix of all these characteristics. Only one objective: to win.

Stiff and responsive where you need it
The V4Rs has peculiar carbon laminations, designed and tested with particular attention to the areas of the frame most subject to tension. Pedalling power is transmitted to the frame immediately and effectively, more than any other bike in the World Tour.

Unparalleled ridebilty and precision
The lightened and revised fork makes the bike much more rideable downhill, in groups and on technical courses.

Narrower front area
The front area of the bike has been optimised with lines that follow and facilitate airflow. The V4Rs is the bike you want to be on when you are alone, in a breakaway, on your way to victory.

Wheels up to 32 mm
The bicycle is evolving: more space for tyres allows us to meet the needs of all cyclists and to be compatible with the largest number of wheels and tyres on the market.

Ceramic Speed SLT headset
The headset bearings are treated with Ceramic Speed's SLT technology, which virtually cuts out the need for any maintenance during the life of the product

Easier bike fitting
The increase in reach and stack between the different geometries is linear: This allows for an easier bike fitting to enable the rider to find the perfect riding position.
