Meet the Prologo Nago R4 PAS Saddle, engineered for peak performance across XC, road, gravel, and MTB riding. This saddle was developed with professional teams and refined through Pressure Map MyOwn testing to deliver maximum comfort and efficiency on long rides. Its compact 245 mm length and forward-centered geometry offer excellent freedom of movement, helping you pedal with power in any position.

The base uses long-fiber carbon, balancing stiffness with a comfortable feel. Two independent sections with the latest generation of variable-density foams provide targeted support throughout every phase of the pedal stroke. At the core, the PAS system features a wide central channel and a holed base to minimize pressure peaks even during maximum pedal thrust. The 147 mm version adds extra padding on the sides and top for a wider, more forgiving base compared to the 137 mm option.

Key details include a carbon fiber injection shell, microfiber cover, and Ø7 mm TiroX/Pro-T2.0 rails. Available sizes are 245 × 137 mm and 245 × 147 mm, designed for unisex riders with a forward-leaning, race-oriented stance. The saddle is origin Taiwan (TW).
