Olympic Plate BBR 5/10/15/20/25 kg HMS, covered with high-quality rubber. Its main advantages are a perfect moulding, an aesthetic finish, and a special profile that prevents it from rotating on the bar. The plates are made from premium materials. They are covered with a special thick rubber that absorbs shocks, so that falling plates do not damage the floor. Depending on the weight, the BBR plates HMS reach 75-96 points on the Shore scale. This means that the plates are much harder than cheaper rubber plates available on the market. The weight and dimensions of each plate are calibrated. This means that the weight of the disc is within a margin of +0.5% to -0.5%. The inner diameter has been adjusted to fit Olympic bars. Precise manufacturing ensures the stability of weights during intense training. The sleeve of the plate is made of stainless steel, making it easy to put on and take off the weight from the bar. In addition, this element helps to stabilise the weights on the bar. The O.
