This is a 15 kg Bumper Plate, typically used for Olympic weightlifting, CrossFit, and general strength training.
Material and Build
High-Density Rubber: Unlike traditional iron plates, this is encased in (or solid) dense rubber. This allows the weight to be dropped from overhead or shoulder height without damaging the floor, the bar, or the plate itself.
Low Bounce: These plates are designed to absorb impact, providing a dead blow or a very minimal bounce when dropped.
Steel Inner Ring: The center features a stainless steel or chrome-plated insert. This ensures a smooth fit on an Olympic barbell and prevents the rubber from tearing over time.
