The Nago R4 PAS AGX is the gravel version of the iconic Nago R4, completing Prologo's AGX line of ergonomic saddles.
AGX, which stands for Adventure, Gravel, Cyclocross, is a line of ergonomic saddles designed for gravel and all-road riding. They are built to provide the right balance between performance and comfort on every type of terrain, even over long distances.
Compared to traditional models, AGX saddles feature a more flexible base made from next-generation materials and an extra 2 mm of padding made from low-density foams. These features ensure better shock and vibration absorption without limiting or compromising power transfer, even when riding on rough terrain.
The saddle's signature T-shape offers improved freedom of movement and positioning, delivering comfort and protection in high-friction zones. The rear-positioned anatomical center allows the rider to easily shift positions and use the full length of the saddle. The semi-round anatomical shape provides extra support to the lumbar area, helping maintain a stable position, even for riders with limited pelvic mobility.
The saddle is available with Nack rails (Nano Carbon Fiber), made from carbon fiber, Kevlar, and aluminum filaments, or TiroX rails (light alloy steel), offering excellent vibration absorption. The base is made from long-fiber carbon for the Nack version, or injected carbon fiber for the TiroX version. Both materials offer a great balance between stiffness and comfort.
Features:
- The Multi Sector System features separate, individually mapped zones on the saddle, each made with different interactive foams and single-cell padding.
- Prologo's 3D Slide Control technology enhances grip and rider stability, helping maintain the correct position, even when riding off-road.
- The PAS (Perineal Area System) central channel eliminates pressure peaks and numbness by improving blood flow.
- TiroX rail (light alloy steel) offers enhanced comfort with superior vibration absorption.
- Dimensions: 245 x 137 mm.
- Weight: 155 g with Nack rail or 197 g with TiroX rail.
