Description
The NAGO R4 PAS (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 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 PAS ideal for cyclists with medium flexibility in terms of pelvic rotation.
The ergonomic semi-round shape makes the NAGO R4 PAS ideal for cyclists with medium flexibility of pelvic rotation, while the reduced width of just 137 mm is suitable for people with a not too wide sit bones.
The open version NAGO R4 PAS, features two completely independent separate sections, made with latest-generation variable-density foams, to ensure excellent support and the right comfort during all phases of pedaling. At the center, the Prologo PAS system: a wide central channel and a perforated base, to eliminate pressure peaks even in the phases of maximum push on the pedals.
The base is made of long-fiber carbon, a material that offers an excellent compromise between rigidity and comfort.
Different Rails for every type of cyclist
- 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.
- TiroX rail in light alloy steel, a material with an excellent balance between weight and resistance, which gives the saddle less rigidity and superior vibration absorption, for those seeking greater comfort.
