Prologo NAGO R4 PAS 137 TIROX

The Prologo NAGO R4 PAS 137 TiroX Hard Black is a high-performance saddle developed in collaboration with professional cyclists - a modern version of the iconic NAGO saddle that has already won major races such as the Giro d'Italia. With a compact length of 245 mm and a narrow width of 137 mm, it is perfect for cyclists with narrower sit bones and medium pelvic rotation.
The ergonomic, semi-circular shape provides a balanced mix of freedom of movement and efficient power transfer in all positions. The anatomical center placement is slightly forward for increased pedaling power, and the open PAS system with central channel reduces pressure and increases blood circulation on longer rides.
Made with long-fiber carbon fiber in the base and variable-density padding for support with every pedal stroke, the TiroX alloy steel rails provide the perfect balance of comfort, strength and vibration damping – ideal for long, intense sessions.
