Our DEEP GROOVE™ design is a valley that is carved down the entire length of the saddle. This design relieves the pressure down the center of the saddle and puts the rider in the correct position. You are able to ride longer more comfortably because your weight is positioned correctly on the saddle. Notice the red areas where there is more contact between the rider and the saddle in the areas that are supposed to be supporting a person's weight. Now look at the blue areas where there is less weight and friction.
