This is a closed cell neoprene saddle with differentiated density which differs from the classical neoprene for the following characteristics: - Closed cell, therefore,waterproof so no more problems of "flooding" of the driver's seat in case of rain, with the problem resulting total loss of grip - Different densities, therefore, freedom of movement of the rider to change direction and pressure lightening on it, but at the same time a guaranteed grip when it starts to push on it - Already shaped for each bike with a milled edge to improve rider comfort - High adhesive strength - Possibility of custom shapes
