The Ergon SM Pro Saddle is the saddle choice for men when speed and comfort are designed on the trail or race course. It has Ortho Cell Inlays in the seating area that generate the best possible pressure distribution. The material ensures maximum reset force and is also more durable and lighter than gel.
