Ergon ST Core Evo Saddle

The floating TwinShell design creates a subtle, active suspension effect. As you pedal, the saddle moves slightly with your pelvis, which helps absorb road vibrations and impacts before they reach your lower back, making it feel more forgiving than a standard rigid saddle.

Sizing is based on your sit bone width, not your overall body size. You should measure the distance between your sit bones; the S/M size is designed for a width of 9-12cm, while the M/L size is for 12-16cm.

Yes, it is specifically engineered for touring. The combination of the Orthopedic AirCell Foam and the pressure relief channel is designed to maintain comfort and prevent numbness during extended hours in the saddle.

The anatomically adapted channel is positioned forward to reduce pressure on sensitive soft tissue. By shifting the weight to your sit bones, it significantly lowers the risk of numbness and discomfort during longer rides.

The ST Core Evo uses standard CrMo rails, which are compatible with almost all common bicycle seatpost clamp mechanisms. You should have no issues mounting this to a standard road, hybrid, or touring bike setup.
