Prologo Saddle Nago R4 PAS Nack 137mm

The NAGO R4 (Redesign 4) is the evolution of the iconic NAGO, the Prologo saddle born in 2008 that has already won a Giro d'Italia and numerous Classics over the years. Designed starting from the needs of the professional teams supported by Prologo, the new saddle has been perfected thanks to the “Pressure Map MyOwn” tests, to satisfy the needs of all cyclists looking for maximum performance and comfort even for long rides.

Compact dimensions with a length of 245 mm and T-shape, with a slightly advanced anatomical center, to offer good freedom of movement on the saddle and maximize pedaling efficiency in all positions. The semi-round ergonomic shape also makes the new NAGO R4 ideal for cyclists with medium flexibility in terms of pelvic rotation.
The ergonomic semi-round shape makes the NAGO R4 ideal for cyclists with medium pelvic rotation flexibility, while the reduced width of just 137 mm suits people with a not too wide sit bones.
The closed NAGO R4 features 3 completely independent separate sections, made with latest-generation variable-density foams, to ensure excellent support and the right comfort during all phases of pedaling. Under the central section, Prologo's Active Base system: a base perforated in the center, to combine the benefits of a closed saddle with a larger support surface, with the advantages of an open base.
The base is made of long-fiber carbon, a material that offers an excellent compromise between rigidity and comfort. Rail Nack (Nano Carbon Fiber) composed of carbon fiber, kevlar and aluminum filaments, for the most performance-oriented cyclists looking for maximum rigidity and lightness.
