Prologo Nago R4 137

The NAGO R4 PAS (Redesign 4) is the evolution of the legendary NAGO, the Prologo saddle that was born in 2008 and has already won a Giro d'Italia and many classics over the years. The new saddle was developed based on the needs of professional teams supported by Prologo and has been perfected through "Pressure Map MyOwn" tests to meet the demands of all cyclists seeking maximum performance and comfort even on long rides.

Compact dimensions and a T-shape with a slightly forward-facing anatomical center ensure good freedom of movement on the saddle and maximize pedaling efficiency in all positions. The semi-round ergonomic shape makes the NAGO R4 PAS ideal for cyclists with average pelvic rotation flexibility, while its narrow width of just 137 mm is best suited for riders with narrower sit bone widths. The open version of the NAGO R4 PAS features two separate, completely independent sections made from next-generation foams with variable density to provide excellent support and comfort in all phases of pedaling. At its core is Prologo's PAS system: a wide central channel and a perforated base to eliminate pressure peaks even during maximum pedal thrust.

The base is made from long-fiber carbon, a material that offers an excellent compromise between stiffness and comfort.
