Vélo route Colnago Y1Rs Disc Shimano Dura-Ace Di2 12v Enve WS SES 4.5 DARK

The Colnago Y1Rs Disc Shimano Dura-Ace Di2 12v Enve WS SES 4.5 DARK was designed with a single goal in mind: to maximise speed. This ultra-aerodynamic road bike brings together all of Colnago ’s expertise in a frame developed for top-level competition. It delivers exceptional performance on fast routes, fast-paced classics or the most demanding stages.

The work carried out on the Y1Rs carbon frame minimises aerodynamic drag whilst maintaining impressive stiffness during accelerations and sprints. Every component of the bike contributes to this pursuit of performance, from the fully integrated cockpit to the frame’s specific profiles, which have been tested in a wind tunnel. The result is a bike that is exceptionally stable at high speeds, precise when changing direction and extremely efficient when the pace picks up.

The combination with the Enve WS SES 4.5 carbon wheels adds an even greater level of versatility to the package. Thanks to their differentiated profile and excellent lateral stability, they offer a fast and smooth ride on both long, open stretches and undulating terrain. Their high efficiency allows you to fully exploit the Y1Rs’ aerodynamic potential whilst maintaining stable and precise handling.

The Shimano Dura-Ace Di2 12-speed drivetrain rounds off this premium build with impeccable performance. Gear changes are fast, silent and ultra-precise, whilst the disc brakes ensure total control in all conditions. With its understated and stylish DARK finish, this Y1Rs ‘ Colnago ’ boasts an exclusive style perfectly in keeping with its character as a pure racing bike.
