Colnago Y1Rs | Size S | YSWC | 7.525 kg

Shimano Dura-Ace Di2 with Power Meter | ENVE SES 4.5

This Colnago Y1Rs is a clear example of how an aero road bike can be tailored with precision, combining performance, fit and a strong visual identity.

The customer, a long-time client based in the USA, reached out looking for a high-performance aero bike for his wife, who is also a triathlete. The goal was to create a fast, efficient setup that could match both her riding style and her position on the bike.

Using a detailed bike fit report, we defined every aspect of the setup, from frame size and cockpit dimensions to spacer stack and seatpost setback, ensuring a precise and balanced position. The choice of the YSWC colour scheme was intentional, a tribute to Tadej Pogačar and his remarkable achievements. The build was completed with Shimano Dura-Ace Di2 and a power meter, paired with ENVE SES 4.5 wheels for a well-rounded aero configuration.

The bike was delivered to the US roughly two months after the initial deposit. After some time riding it, the customer decided to push the project further, upgrading to ENVE Pro wheels along with lighter rotors, chainrings and bottle cages to reduce weight even more.

A build that continues to evolve, just like the rider behind it.
