The contact mechanics between the butt and the saddle in a bicycle have not changed in 100 years. When you ride a bicycle, the full body weight rests on two small bones (ISCHIUM). If you wonder why riding bicycles can be uncomfortable, here is why. The constant pressure on those two small bones builds tenderness and discomfort during long rides. Furthermore, since you are putting pressure in a small are of the butt, you are limiting circulation in that small area. Limiting circulation has other implications such as leading to painful saddle sores. If riding performance is important to you, saddle pressure and contact in small, narrow area reduces performance due to micro-sliding on the saddle created by the pedal cycle.
Cushion-Aid technologies are designed to increase the contact area and cradle the ISCHIUM bones on the saddle to reduce micro-sliding, prevent saddle sores and provide comfort during long rides.
