 This is to eliminate the crushing injuries experienced by riders.In standard seats the weight of the rider is often supported at the contact point between the pelvic bone and nose of the seat.The high pressure caused by the small contact area causes crushing injuries in the perineum over the center of the nose, and the muscles and tendons connecting to the interior side of the "sit bones" (ischial tuberosities) at the back of the inner thighs over the sides of the "nose".
