Description

The new Nago R4 PAS AGX is the semi-round, T-shaped saddle that completes Prologo’s AGX line. It is the gravel version of the iconic Nago R4. AGX, which stands for Adventure Gravel Cyclocross, is a line of ergonomic saddles designed for gravel and all-road riding, 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.
Features:
– T-shape and semi-round profile
– 2 mm extra padding
– 3D Slide Control for enhanced grip and stability
– Multi Sector System to adapt to rider morphology
– PAS channel to prevent pressure peaks
– Carbon fiber base
Anatomical Shape:
– 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 of the Nago R4 AGX provides extra support to the lumbar area, helping maintain a stable position, even for riders with limited pelvic mobility.
Base and Rails:
– TiroX rails (light alloy steel), offering excellent vibration absorption.
– The base is made from injected carbon fiber for the TiroX version. Both materials offer a great balance between stiffness and comfort.
Specifications:
– Dimensions: 245 x 137 mm
– Weight: 197 g with TiroX rail
Technology:
– 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. The ergonomic design and variable-density foams help reduce pressure points in the perineal area.
