The NAGO R4 PAS saddle in the Nack Rail version is the ideal high-performance saddle for demanding cyclists. With its open PAS channel, the saddle ensures effective pressure relief in the perineum area and improves blood circulation, which provides additional comfort, especially during long journeys and intense efforts. Its ergonomic T-shaped allows a flexible sitting position and promotes efficient power transmission, thus optimizing performance while driving. Thanks to its injected carbon base, the saddle offers great stability while being light. The carbon nanofiber rear bar provides excellent rigidity and maximum performance, while the combination of lightness and superior vibration damping greatly improves driving characteristics over long distances. Ideal for cyclists looking for both performance and comfort.
