Nago R4 147 - WorldTour Special Edition

Special edition Nago R4 147 saddle, featuring the prominent ‘Big O’ on the cover and customized graphics in the colors of the World Tour teams sponsored by Prologo — celebrating their achievements and delivering top-level performance.

The NAGO R4 147 is a high-performance, multidisciplinary saddle designed to meet the needs of professional riders. Refined through “MyOwn Pressure Map” testing, this saddle is built to satisfy all cyclists looking for maximum performance and long-ride comfort.

The Nago R4 147, which practically won everything in the 2024 season with Tadej Pogačar, is the evolution of the iconic NAGO saddle—originally launched by Prologo in 2008 and winner of a Giro d’Italia and numerous Monument Classics over the years.

Anatomical Shape

The T-shape design ensures greater freedom of movement thanks to a wider seating area.
The rear-positioned anatomical center allows the rider to easily change positions and take full advantage of the saddle’s length. Its semi-round ergonomic shape makes the NAGO R4 ideal for cyclists with medium pelvic rotation flexibility, while the 147 mm width makes it suitable for cyclists with a wider ischial bone distance, who therefore require a broader support base on the saddle.

Compared to the 137 mm NAGO R4, the 147 mm version features increased padding: 10 mm more on the sides and 3 mm more on the top. It is specifically designed for riders with a higher Body Mass Index (BMI), who can benefit from the extra padding for better weight distribution, as well as for cyclists simply seeking a more cushioned and comfortable saddle.

Technologies

The closed version of the NAGO R4 features three fully independent sections, made with next-generation variable-density foams to provide the right support and comfort throughout every phase of pedaling. Under the central section lies the Active Base system by Prologo: a cut-out in the base, designed to combine the benefits of a closed saddle—offering a wider contact surface—with the comfort advantages of an open-base design.

Base and Rails

The long-fiber carbon base and Nack rail (nano carbon fiber) make the saddle lighter, stiffer, and more efficient. The version with injected carbon base and Tirox rail (light alloy steel), offers an excellent balance of weight and durability, with greater vibration absorption and slightly less stiffness.
