The Prologo NAGO R4 AGX PAS saddle is a semi-round T-shaped saddle designed for gravel, all-road and adventure riding. It provides a balanced combination of performance and comfort even over long distances and driving in challenging, uneven terrain. The ergonomic T-shape allows for free movement and easy position changes on the saddle, while protecting sensitive areas from excessive friction. The anatomical center shifted to the rear helps to effectively use the entire surface of the saddle, and the semi-circular profile improves support in the lumbar area, which will be especially appreciated by riders with less pelvic mobility.

The base made of more flexible new generation materials combined with a 2 mm thicker lining made of low-density foam ensures excellent shock and vibration absorption without negatively affecting the transfer of power to the pedals. The Multi Sector System technology divides the saddle into zones with different foam densities for better adaptation to the body's shape, while the 3D Slide Control with micro-patterning on the surface increases grip and stability when riding off-road. The central PAS channel reduces pressure in the perineal area, improves blood circulation and increases overall comfort on long rides.

The saddle construction uses a fiber-reinforced carbon base and Tirox lightweight steel alloy rails, which offer the ideal balance of weight, strength and vibration absorption. Compact dimensions of 245 × 137 mm and a low weight of 197 g make this saddle a suitable choice for both performance and hobby riders looking for stable support and high comfort in various conditions.
