Colored competition bumpers are designed to meet IWF standards and offer unrivalled weight accuracy with a tolerance of just +/- 10g. Made from high-density virgin rubber, they guarantee minimal rebound for greater safety and stability during your weightlifting training and competitions.
The patented stainless steel center collar ensures better shock absorption and increased durability, preventing premature wear in contact with the rubber. Their textured surface with embossed lettering facilitates handling, while the raised lip around the edge of the disc offers a better grip.
Tested to withstand over 30,000 falls, these discs are the perfect choice for weightlifting, bodybuilding and cross-training facilities, guaranteeing optimum longevity even under intensive use.
