Prologo Nago R4 PAS TIROX 147 saddle

The NAGO R4 PAS (Redesign 4) is the evolution of the iconic NAGO, the Prologo saddle born in 2008, which has already won the Giro d'Italia and numerous classics in previous years. The new saddle, designed based on the needs of the professional teams supported by Prologo, has been refined through “Pressure Map MyOwn” testing to meet the needs of all cyclists looking for maximum performance and comfort even on long rides.

Compact dimensions with length 245 mm and T-shape, with a slightly forward anatomical center that provides good freedom of movement in the saddle and maximizes pedaling efficiency in all positions. The semicircular ergonomic shape makes the NAGO R4 PAS ideal for cyclists with average pelvic rotation flexibility. Compared to the NAGO R4 PAS 137 mm, the 147 version has 10 mm more padding on the sides and 3 mm on the top and is suitable for: cyclists with a wider seat bone spacing, who therefore need a wider base for support on the saddle; cyclists with a high body mass index (BMI), who can benefit from increased padding for better weight distribution; cyclists looking for an even more comfortable saddle.

The open version of the NAGO R4 147 PAS has two separate, completely independent parts, made of the latest generation of variable density foam, which provides excellent support and comfort during all phases of pedaling. At the heart of the Prolog PAS system: wide central channel and perforated bottom to eliminate pressure peaks even during the phases of maximum pedaling. The base is made of long-fiber carbon, a material that offers an excellent compromise between stiffness and comfort. TiroX seatstays in lightweight alloy steel, a material with an excellent balance between weight and strength, giving the seat less stiffness and superior vibration damping, for those looking for more comfort.
