Prologo Nago R4 147 Nack Saddle - Black

Prologo Nago R4 147 Nack Saddle – Superior Comfort and Professional Performance

The Prologo Nago R4 147 Nack is a multidisciplinary, ergonomic, and high-performance cycling saddle designed to meet the needs of professionals and the most demanding cyclists. Developed through advanced Pressure Map MyOwn testing, it offers the perfect balance between top performance and comfort even on long rides.

The Nago R4 147, the absolute star of the 2024 season alongside Tadej Pogaar, represents the evolution of the historic NAGO, introduced in 2008 and already winner of a Giro d’Italia and numerous Classics.

Anatomical Shape and Optimized Support

The T-shape structure ensures greater freedom of movement thanks to a wider support surface. The rearward anatomical center allows the cyclist to easily change position during pedaling, utilizing the full length of the saddle.

The ergonomic semi-round shape is ideal for cyclists with medium pelvic rotation flexibility, while the 147 mm width is designed for those with a greater distance between the ischial bones and therefore need a wider base.

Compared to the 137 mm version, this variant offers:

• +10 mm padding on the sides
• +3 mm on the top

An ideal solution for:

• cyclists with high BMI
• those looking for an even more comfortable and cushioned saddle
• better weight distribution during pedaling

Advanced Technologies for Maximum Comfort

The closed version of the Nago R4 is built with 3 independent sections, made with variable density foams, to ensure support and comfort at every stage of the pedal stroke.

Prologo’s Active Base system, with a centrally perforated base, combines:

• greater support surface area (typical of closed saddles)
• pressure reduction (advantages of open saddles)

Result: prolonged comfort and better force distribution.

Premium Materials: Lightness and Performance

The saddle is available in two technical configurations:

• Long fiber carbon base + Nack Rail (nano carbon fiber)
  → maximum lightness, stiffness, and racing performance
• Injected carbon base + Tirox Rail (light alloy steel)
  → better vibration absorption and excellent weight-strength ratio
