Pro-Level Semi-Round Saddle with Active Base

Description

The Prologo Nago R4 Nack 147 Saddle is a multi-purpose, high-performance platform developed for professional-level demands. Perfected through Pressure Map MyOwn testing, it delivers maximum performance and comfort even during long and intense rides.

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

Semi-Round Ergonomics For Balanced Support: Its ergonomic semi-round shape makes it ideal for riders with medium pelvic rotation flexibility. The 147 mm width provides a wider support base, perfect for cyclists with broader sit bone spacing.

Active Base Technology: Under the central section, Prologo’s Active Base system features a perforated base design. It combines the larger support surface of a closed saddle with the pressure-relief advantages typically found in open constructions.

Lightweight Carbon Construction: The long-fiber carbon base enhances stiffness and reduces weight, improving overall efficiency. This structure supports strong power transfer without compromising ride comfort.

Nack Rail For Maximum Performance: Equipped with a Nack rail made from nano carbon fiber, the saddle achieves exceptional rigidity with minimal weight. It’s built for riders seeking uncompromising race-day performance.

The Prologo Nago R4 Nack 147 Saddle blends heritage, innovation and elite performance for cyclists who demand speed and comfort at the highest level.
