The kit includes a total of 100 Kg of Crumb Bumper Plates [Link] divided into two 5 kg plates (code 9040/7), two 10 kg (code 9042/7), two 15 kg (code 9043/7) and two 20 kg (code 9044/7). The discs in this line are made entirely from recycled rubber granules from shoes. These are not bumper discs made from new vulcanised rubber and only covered with a layer of recycled rubber granules, but discs made entirely from recycled rubber granules joined by high temperature. This is why the 20 kg disc has a small metal core inside to achieve the weight, while maintaining the 450 mm diameter, with an acceptable thickness.
