Ergon ST Core Evo

The twin-shell construction uses two separate layers that move independently. This allows the saddle to flex and adapt to your pelvic movement while you pedal, which significantly reduces pressure on your sit bones compared to a rigid, single-piece saddle.

Unlike traditional gel, which can bottom out or feel squishy, the BASF Infinergy core acts like a high-rebound foam. It absorbs road vibration and impacts while maintaining a supportive, springy feel that returns energy to your pedal stroke.

This saddle is specifically engineered for endurance and comfort over long distances. The combination of the ergonomic relief channel and the dynamic core makes it an excellent choice for all-day rides, touring, or long weekend gravel sessions.

Ergon sizes their saddles based on sit-bone width rather than overall body size. The Medium/Large option is designed for riders with a wider sit-bone measurement, typically providing better support and stability for those who need a broader platform.

Yes, the anatomically optimized relief channel is designed to alleviate pressure on sensitive soft tissue. By shifting weight onto the sit bones and away from the perineal area, it effectively reduces the numbness often experienced during longer rides.
