It is the result of in-depth ergonomics studies. It supports the cyclist's weight precisely distributing it over pelvic bones (ischial tuberosities) and buttocks. It protects the coccyx from bruises and shocks caused by the roughness of the terrain.
Distributed along the whole length of the saddle, from the rear to the tip. Whatever the cyclist's position, it prevents delicate perineal structure compression, avoiding vein and capillary vessel occlusion and the chance of nerve injury.
