The Prologo Proxim W850 ergonomic MTB saddle is specially designed for E-bike and Gravity disciplines and was created in collaboration with world racing teams. Thanks to its V-shaped shell and ergonomic center, it is suitable for both men and women. The saddle surface has been designed for maximum comfort when pedaling uphill, when most of the weight is concentrated on the back of the saddle.

The new Multi-Sector System (MSS) improves comfort and performance through active foam pads that are separated from each other, creating independent zones with different properties for maximum rider comfort. These pads also absorb vibrations transmitted by the base. The PAS (Perineal Area System) is a channel designed to eliminate pressure peaks, numbness, and improve blood flow. Its ergonomic design with variable density foams eliminates contact points in the prostatic-genital area, making it ideal for users who prefer performance combined with comfort over long and medium distances.

  • Skeleton made of nylon flexible material
  • Multi-Sector System (MSS) technology
  • Perineal Area System (PAS) technology
  • Grip Cover for better grip on the back of the saddle
  • Designed for E-bike and Gravity disciplines
  • Suitable for both men and women
