The ergonomic saddle revolution for touring bikes. The floating TwinShell with ergonomic core supports the natural pelvic movements while pedalling, actively relieves the sit bones, and reliably dampens vibrations caused by the riding surface. The core consists of the latest E-TPU materials, bringing state of the art technology in responsiveness and damping. The saddle shape has been anatomically perfected specifically 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. Upper Saddle Shell: The flexible upper shell connects the ergonomic core with the seat padding and allows the flexibility of the ST Core. Ergonomic Core: The core supports the natural movement of the hips and dampens the effect of constant bumps. Lower Saddle Shell: The lower stiff saddle shell holds the base and guides the absorbed vibrations into the ergonomic core. Pronounced Relief Channel: The Relief channel helps to avoid numbness and provides increased protection for soft-tissue areas. Anatomical Shape: The wide, comfortable seat area is matched to an upright or slightly inclined seating position – the typical posture of a touring rider. Movement & Relief: The ergonomic core ensures all pelvic movements are supported and pressure on the seat bones is actively relieved with every rotation of the pedal.
