The NAGO R4 PAS is the evolution of the iconic NAGO, the Prologo saddle born in 2008 that has already won a Giro d´Italia and many Classics over the years. Designed from the needs of professional teams supported by Prologo, the new saddle has been perfected through ´´Pressure Map MyOwn´´ testing to meet the needs of all cyclists seeking maximum performance and comfort even for long rides.

Compact dimensions with a length of 245 mm and T-shape, with a slightly forward anatomical center, to provide good freedom of movement in 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, the narrow width of only 137 mm, best suit riders with lower ischial bone width.

The NAGO R4 PAS open version, features two separate fully independent sections, made of the latest generation of variable density foams, to ensure excellent support and comfort during all phases of pedaling. At the center there is Prologo´s PAS system: a wide central channel and a holed base to eliminate pressure peaks even during maximum pedal thrust phases.

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

Different rails for every type of cyclist:
- Rail Nack (Nano Carbon Fiber) composed by carbon fiber, Kevlar and aluminum filaments, for more performance-oriented cyclists seeking maximum stiffness and lightness.
