Ergon ST Core Evo

The twin-shell construction creates a floating sensation. Because the upper shell is decoupled from the base by the Infinergy core, the saddle absorbs road chatter and bumps before they reach your sit bones, making for a noticeably smoother ride on rough pavement or gravel.

While the ST Core Evo is designed primarily for comfort and endurance, it is stable enough for spirited riding. However, if you prefer a very stiff, minimalist saddle for racing, you might find the dynamic movement of this core a bit too active for your taste.

The female-specific model features a wider relief channel and a different pressure distribution profile to match the female pelvic anatomy. This ensures that the cutout aligns correctly with sensitive tissue to prevent numbness and discomfort during long hours in the saddle.

Unlike traditional leather saddles, this model does not require a break-in period. The ergonomic shape and the Infinergy core provide immediate comfort from the first ride, though you may need a few rides to fine-tune your fore-aft position and tilt.

The BASF Infinergy material is highly durable and designed to retain its energy-returning properties over thousands of miles. It is resistant to temperature fluctuations and fatigue, so the shock-absorbing performance should remain consistent throughout the life of the saddle.
