Ergon ST Core Evo

The twin-shell design uses a floating lower shell that moves independently from the upper shell. This allows the saddle to follow your pelvic motion as you pedal, which significantly reduces pressure on your sit bones compared to a rigid, single-piece saddle.

Infinergy is an expanded thermoplastic polyurethane that acts like a high-performance shock absorber. It provides excellent rebound and vibration damping, effectively smoothing out road chatter and bumps without feeling overly squishy or unstable.

This saddle is designed specifically for endurance and long-distance riding. The combination of the dynamic shell movement and the pressure-relief cutout makes it well-suited for extended hours in the saddle where comfort is the primary priority.

Yes. The relief zone is anatomically shaped to address the specific pressure points and pelvic structure typical of female riders. By aligning the cutout and padding density with these needs, it helps prevent numbness and discomfort during longer rides.

Not at all. While the shell adapts to your movement, it is engineered to provide a supportive platform. You will feel the saddle moving with you, but it remains firm enough to maintain efficient power transfer while pedaling.
