Colnago Y1Rs (Shimano Dura Ace di2 12s)

Colnago Y1Rs Shimano Dura-Ace Di2 – Ultimate Aero Road Race Bike

The Colnago Y1Rs Shimano Dura-Ace Di2 is a cutting-edge aero road bike engineered for maximum speed at the highest level of racing. Developed through extensive CFD analysis, wind-tunnel testing and professional race experience, the Y1Rs combines radical aerodynamics, exceptional stiffness and unmistakable Italian design.

Created for riders who want uncompromising race performance, the Colnago Y1Rs reduces frontal area by 19% compared with the V4Rs. Colnago's aerodynamic testing shows a saving of up to 20 watts at 50 km/h, making the Y1Rs an exceptional choice for fast racing, breakaways, sprints and high-speed road riding.

Shimano Dura-Ace Di2 12-Speed

This premium Y1Rs build features Shimano Dura-Ace Di2 12-speed, Shimano's flagship electronic road groupset.

Fast, precise electronic shifting combines with powerful Dura-Ace hydraulic disc brakes for exceptional control and race-ready performance. A 52/36T chainset paired with an 11-30T cassette provides a versatile gearing range designed for fast road riding and racing.

ENVE SES 4.5 Carbon Wheels

The ENVE SES 4.5 carbon wheelset complements the aerodynamic Y1Rs frameset with a fast, versatile wheel platform designed for real-world racing.

Combining aerodynamic efficiency with confident handling, the SES 4.5 wheels make this build equally at home attacking on rolling roads, powering across exposed terrain or racing at high speed in the bunch.

Colnago CC.Y1 Integrated Aero Cockpit

One of the defining features of the Y1Rs is the distinctive Colnago CC.Y1 integrated carbon cockpit with WYND© technology.

Its innovative shape has been designed to manage airflow around the front of the bike while reducing frontal area. Fully integrated cable routing creates an exceptionally clean profile and contributes to the Y1Rs' aerodynamic performance.

Engineered for Speed

The Y1Rs introduces a number of distinctive aerodynamic solutions, including its bayonet-style fork, sculpted downtube and innovative Y-shaped seatpost junction.

The frame is also 3.5% stiffer than its predecessor, helping translate hard accelerations and sprint efforts directly into forward speed without compromising the ride quality expected from a flagship Colnago race bike.

Despite its aero-focused design, this Shimano Dura-Ace and ENVE SES 4.5 build has an approximate weight of just 7.54 kg in size M without pedals, creating a race bike that combines aerodynamic efficiency with competitive weight.
