Seamless integration, premium carbon construction, and pure Colnago efficiency.

Every single component on a premium custom build deserves absolute dedication, which is exactly why Colnago engineered this dedicated accessory. The official Colnago Seatpost for Y1rs is the definitive choice to complete your setup, establishing a perfect technical synergy while elevating both the race performance and the clean lines of your frame.

Crafted entirely from high-modulus carbon fiber, this seatpost is a genuine lightweight component, tipping the scales at just 190 grams. It provides discerning riders with an exquisite balance between high structural stability, weight savings, and vertical compliance over long miles. Its custom aerodynamic profile has been sculpted and engineered specifically to follow the lines of the Y1rs frame. This precise fit is not just about striking aesthetics—it guarantees a clean, integrated airflow that significantly minimizes drag around the seat tube junction.

To help you achieve your perfect biomechanical fit and unlock maximum power transfer on the pedals, the seatpost is available in two distinct configurations: with a 0 mm setback (ideal for a forward, aggressive racing posture) or a 15 mm setback (tailored for a more traditional, centered position). The high-precision clamp system allows for micro-adjustments and secures the saddle rails effortlessly, completely eliminating slipping even on rough road surfaces.
