Precision Co-Molded Construction: Each plate is vulcanized under high pressure to ensure the rubber is perfectly bonded to the internal hub, preventing separation even under extreme use.
* IWF Standard Dimensions: Consistent 450mm outer diameter across all weights (5kg to 25kg / 10lb to 55lb), ensuring all plates hit the floor simultaneously to distribute force evenly.
* Reinforced Stainless Steel Insert: A precision-machined 50.4mm – 51mm center hole fits all standard Olympic bars snugly, reducing "clack" and wear on the bar sleeves.
