The competition bumper plates are made of virgin rubber and stainless steel hub. These plates are ideal for any life style, and they excel in Olympic weightlifting and even powerlifting given their low bounce and narrow width. The competition plates have an extremely low bounce. Generally, the durometer is around 90-94SHA. When you drop these plates from overhead, you can rest assured that you're not going to have to chase the bar around. Besides classic style, we accept customization and provide customers with more value-added bumper plates, such as a new appearance design, to bring customers a higher brand recognition.
