Bells of Steel Competition Bumper Plates

Competition plates are engineered for precision and durability. Unlike standard bumpers, these feature a calibrated weight tolerance of 0.1% and a thinner profile, allowing you to load more weight onto the barbell sleeve.

The high-density virgin rubber construction minimizes bounce when dropped. This keeps the barbell from rolling away or bouncing unpredictably, which is essential for maintaining control and safety during heavy lifts.

Yes, these plates are designed with a 50.5mm center hole, which is the industry standard for Olympic barbells. The stainless steel hub ensures a smooth, secure fit that won't damage your bar's sleeves.

While they are built with durable virgin rubber and stainless steel, they are primarily designed for indoor gym environments. Prolonged exposure to extreme weather or direct sunlight can degrade the rubber over time.

The durometer rating measures the hardness of the rubber. A rating of 85-95 indicates a firm, dense plate that provides the 'dead blow' feel preferred by competitive lifters, ensuring the plates don't deform or wobble during heavy sessions.
