The organic pads are made with a semi-metallic compound rich in organic material that allows them to have a more ready bite (because the pad heats up very quickly and therefore enters an optimal temperature) and a very low noise because it is softer.Having less metal component, the pad is less suitable for handling very high temperatures.The duration of the organic tablet is the shortest:consider that our organic tablet has a double life to an organic tablet of the competition and even triple to a shimano (which is made of resin, therefore extremely soft).PRODUCT SHEET.TECHNICAL DATA.-SERIES:P21.-DESCRIPTION:organic tablet.-CHARACTERISTICS:quicker bite with very low noise despite higher consumption
