Prologo Nago R4 Tirox 147 Saddle

The Prologo Nago R4 Tirox 147 Saddle is a multi-purpose, high-performance saddle developed for professional riders and demanding cyclists. Perfected through Pressure Map MyOwn testing, it delivers maximum efficiency and comfort, even during long and intense rides.

A Proven Winner At The Highest Level: The Nago R4 147 dominated the 2024 season alongside Tadej Pogačar, continuing the legacy of the iconic Nago introduced in 2008. Over the years, this platform has secured victories at the Giro d’Italia and major Grand Classics.

T-Shape Design For Freedom Of Movement: The T-shape profile offers greater freedom thanks to its wider seating area. The set-back anatomical center allows riders to easily shift positions along the saddle length for optimal power and control.

Closed Structure With Active Base System: This closed version features three independent sections made with next-generation variable density foams. Beneath the central section, Prologo’s Active Base system uses a perforated design to combine the support of a closed saddle with the flexibility benefits of an open structure.

Balanced Comfort & Support: The multi-density foam construction ensures consistent support throughout the pedal stroke. It enhances stability while maintaining comfort during sustained efforts and varied riding conditions.

Tirox Rail & Injected Carbon Base: The injected carbon base paired with a Tirox light alloy steel rail provides an excellent weight-to-strength balance. This setup reduces excessive rigidity while improving vibration absorption for smoother ride quality.

The Prologo Nago R4 Tirox 147 Saddle blends race heritage, structural innovation and refined comfort for cyclists who demand performance across disciplines.
