This model has been demoed or previously mounted.

Dimensions: 145mm width and 240mm length

Weight: 250 grams.

Material: Titanium rails.

The OPTIMA S shares the sleek, low-profile silhouette of our MODUS saddle, built around Reactive Padding™ 2.0.

A shorter nose than other Optima Ti models and a flatter profile across the top let you change position without fighting the saddle. At 240mm long, 145mm wide and 250g, it is light without giving anything up in support.

Our founder designed Zeta's padding around the two things a pressure mat can actually measure: how hard a saddle loads your sit bones, and how hard it presses in the perineal zone between them. Contact pressure, friction and the ground reaction forces travelling up through the bike all build over the course of a ride — and most saddles answer that by adding foam, which compresses and stops helping.

In April 2024, nine saddles were measured on a gebioMized pressure mat by an independent engineer and a professional bike fitter. A Zeta model recorded the lowest peak pressure in each of the two zones measured, and no conventional saddle in the test was lower in both. Every number is published.

Designed by a doctor and avid cyclist, Zeta Saddles patented Reactive Padding™
