Colnago Y1Rs Road Bike Frameset - Black Edition YSBC - World Champion

Developed around Colnago’s most advanced aerodynamic road platform, the Colnago Y1Rs Black Edition YSBC Road Bike Frameset combines race-focused engineering with a distinctive dark finish. Designed for riders seeking maximum efficiency at high speeds, it brings together advanced carbon construction, integrated aerodynamics and precise handling in a platform developed for top-level competition.

The Y1Rs was shaped through extensive wind-tunnel testing and computational fluid dynamics analysis. Its tube profiles, frame junctions and exposed surfaces are designed to manage airflow efficiently and reduce aerodynamic drag, while retaining the responsive character and predictable handling expected from a Colnago race frame.

High-modulus carbon-fibre construction provides the stiffness required for direct power transfer during accelerations, climbing efforts and high-speed riding. The frame is engineered to balance rigidity, structural strength and controlled handling across demanding race conditions.

At the front, the proprietary Bayonet fork contributes to the frameset’s aerodynamic profile and fully integrated appearance. Internal cable routing keeps brake hoses and electronic drivetrain wiring concealed, supporting both cleaner airflow and a minimal overall aesthetic.

The frameset is designed around modern electronic drivetrain systems, flat-mount disc brakes and 12 mm thru-axles. CeramicSpeed SLT-treated headset bearings complete the front-end assembly, providing a durable, low-maintenance interface for the integrated steering system.

Finished in Colnago’s YSBC Black Edition colourway, the Y1Rs presents a restrained and technical appearance that highlights the frame’s distinctive aerodynamic architecture.
