Colnago V4Rs Ultegra Di2 Road Bike

Built to Win

The Colnago V4Rs Ultegra Di2 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 with improved stiffness, better aerodynamics, and decreased weight.

A winning bicycle must be stiff, light, aerodynamic, comfortable and robust. The V4Rs is today’s best road bike via a mix of all these characteristics.

Stiff, Responsive, Light, Aero, Simple

The V4Rs has unique carbon laminations, designed and tested with particular attention to the areas of the frame most subject to tension. Pedaling power is transmitted to the frame immediately and effectively, more than any other bike in the World Tour. The front area of the bike has been optimized 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.

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

Fitting is made easier since the increase in reach and stack between the different geometries is linear, enabling any rider to find the perfect riding position.

Colnago uses actual seatube length for their size measurement. Please use the geometry chart to determine the correct size. If you have any questions please feel free to contact us and our Customer Service team will be happy to help you determine your proper size.
