Prologo Nago R4 PAS Saddle - black

The NAGO R4 PAS is an open, high-performance multifunction saddle specifically tailored to the needs of professional cyclists. Thanks to the “MyOwn Pressure Map” tests, this saddle meets the requirements of all riders seeking maximum performance and long-distance comfort.

This model is the PAS channel version of the NAGO R4, the evolution of the legendary NAGO saddle, a Prologo classic, first introduced in 2008 and has won a Giro d'Italia and several Monument Classics over the years.

Anatomical shape
The T-shaped design provides more freedom of movement thanks to a wider seating area. The rearward anatomical centre allows the cyclist to easily change position and fully utilise the saddle length.  The semi-round ergonomic shape makes the NAGO R4 PAS ideal for riders with average pelvic rotation flexibility, while the narrow width of 137 mm is suitable for riders with medium sit bone distance.

Technologies
This open version of the NAGO R4 features two completely independent areas made of foam of different densities of the latest generation to provide optimal support and comfort at every stage of the pedal stroke. The central PAS channel (Perineal Area System) has been specifically designed to relieve pressure peaks and numbness, thereby improving blood circulation and overall comfort.

Base and rails
The frame is available in Nack (Nano Carbon Fiber): Made from carbon fibre, Kevlar and aluminium filaments - ideal for riders seeking maximum stiffness and lightness - or in Tirox (light steel alloy): offers excellent vibration damping and an optimal weight-to-strength ratio. The base is made from long carbon fibres (Nack frame), from injected carbon fibres (Tirox frame). Materials that provide an optimal balance between stiffness and comfort.
