The Ergon ST Core Evo saddle features an ergonomically shaped relief channel designed to provide comfort over long distances. It utilizes a twin shell construction with a BASF Infinergy core sandwiched between layers to isolate the rider from the road surface. The ergonomic core dynamically adapts to pelvic motion, providing a floating ride sensation. Gender-specific relief zones accommodate the unique anatomical differences of male cyclists. The 3D damping system adapts to pelvic motion with minimal pressure and reduced friction.
