Open PAS Race Saddle with Tirox Stability

Description

The Prologo Nago R4 PAS Tirox Saddle is an open, high-performance multi-discipline saddle developed for professional-level demands. Refined through Pressure Map MyOwn testing, it delivers outstanding performance and long-ride comfort for serious cyclists.

Legacy Of A Winning Platform: The 147 mm PAS version continues the evolution of the iconic Nago, first introduced in 2008 and a winner of Grand Tours and major Classics. It blends proven race heritage with modern ergonomic refinement.

Semi-Round Shape & 147mm Support: The ergonomic semi-round profile suits riders with medium pelvic rotation flexibility. Its 147 mm width offers a wider base of support, ideal for cyclists with broader sit bone spacing.

Dual Independent Padding Structure: The open design features two independent sections built with next-generation variable density foams. This construction enhances support through the full pedal stroke while improving overall comfort.

PAS Channel For Pressure Relief: The central PAS (Perineal Area System) channel reduces pressure peaks and numbness. It promotes better blood flow and maintains comfort during intense or sustained efforts.

Tirox Rail & Carbon Base Construction: The Tirox rail, made from light alloy steel, offers excellent vibration absorption and durability. Combined with an injected carbon base, it achieves a balanced mix of stiffness and riding comfort.

The Prologo Nago R4 PAS Tirox Saddle delivers open-channel comfort, race-level efficiency and dependable support for demanding road and multi-discipline cyclists.
