Colnago has launched their brand new V4Rs. Back in July, Colnago debuted a new bike at the Tour de France, a model which they were calling the 'Prototipo' . It was rumored that was going to be the new V4Rs, 6 months later and Colnago have done it, here is the first look at the brand new Colnago V4Rs. Since the V3Rs had such a good winning pedigree, the new V4Rs has big boots to fill, but will it manage it?

Colnago claims to have improved the new bike's aero credentials, weight, stiffness and durability. Sam Gupta takes a closer look at the detail and tries to work out if it really is the next winning machine.
