PRx Crumb Rubber Bumper Plates

Made of recycled material, crumb rubber weight plates are one of the toughest training weights available! In the combination of strength and price, crumb rubber has no equal competitors. The PRx Crumb Rubber Bumper Weight Plates use recycled crumb rubber for less impact on the floor (and less noise) than steel weight plates. With proven durability, they have been tested to withstand 30,000 drops. Sold in pairs.
