The Prologo Nago R4 PAS AGX is a T-shaped, semi-round gravel saddle engineered for long all-road and off-road rides. Part of Prologo’s AGX (Adventure, Gravel, Cyclocross) line, it balances comfort and performance with a more flexible base and 2 mm extra low-density foam padding to improve shock and vibration absorption without compromising pedalling efficiency.
Comfort and fit: The Signature T-shape and rear-positioned anatomical center give riders freedom of movement and easy position changes while protecting high-friction zones. The PAS (Perineal Area System) central channel reduces pressure peaks and numbness for better blood flow and comfort over long distances.
Technology: The Multi Sector System uses individually mapped zones with different interactive foams and single-cell padding to target support where you need it. 3D Slide Control increases grip and stability, keeping you secure on rough terrain. TiroX rails (light alloy steel) provide a strong yet vibration-damping connection suited to riders prioritising comfort.
Key specifications:
Use: Designed for gravel, bike touring and road/all-road use where long-distance comfort and reliable power transfer are required.
