ST Core Prime Women black

The ergonomic saddle revolution for touring bikes ensures maximum long-distance comfort for men and women. The floating TwinShell concept with the Ergonomic Core supports the natural pelvic movements while pedaling, actively relieves the sit bones, and reliably dampens bumps caused by the riding surface.

The core consists of Infinergy®, the latest E-TPU material bringing state of the art technology in responsiveness and damping. The anatomically adapted seating area has been optimized in elaborate studies and field tests for men and women. Thanks to the significant relief channel, numbness and pain are effectively prevented. The new ST Core Saddle is tailored in detail to the needs and requirements of touring and e-bike riders around the world.

Maximal Comfort for Men and Women

In addition to the construction of the saddle, the gender specific form of the seating area is also brand new. In the genital area, men and women differentiate strongly. It is most often in this area that pressure points lead to numbness and difficulties while riding.

Ergon has designed the relief surfaces using the latest scientific research and extensive testing. The results are gender specific shapes and relief channels – creating maximum comfort for women and men.

The Right Size

The shape and size of the saddle must match the sit bone width of the rider to maximize comfort and enjoyment.

The pelvic bone has a unique V-shaped and the saddle must offer the sit bones a large contact surface with the ability to meet the demand of different sitting positions. Various saddle widths are offered so that the usable seat surface corresponds to the riders unique sit bone distance.

The more forward and aggressive the rider sits, the further forward the sit bones contact the saddle.
