Competition Bumper Plates (LB), Sets and Pairs

PRODUCT OVERVIEW

Competition bumper plates are crafted to meet rigorous International Weightlifting Federation (IWF) standards, a key factor for serious athletes seeking reliability and precision. Each plate must meet the IWF-mandated 45cm diameter, and XMARK’s weight tolerance is 10 grams, the weight of two nickels™ of the stated weight, guaranteeing accurate weight loads during high-level training. This precision is essential for athletes needing consistency in every lift. Plates are also color-coded according to IWF standards, allowing for easy identification and swift weight changes, which is especially beneficial in competitive environments.

Manufactured with our proprietary virgin rubber blend, XMARK’s competition plates are built to handle intense, repetitive use while minimizing damage to floors and equipment. Chrome-plated premium-grade steel inserts reinforce the plate, reducing wear on barbells and ensuring a secure, lasting fit on the bar. The plate’s Shore A Durometer rating of 90, balances hardness and impact absorption, preventing excessive bounce and enhancing safety. To confirm durability, these plates undergo extensive drop testing, 30,000 times from 8-feet, simulating the demands of a commercial gym setting or competition arena. Their precision engineering and low-bounce construction make them ideal for advanced lifters looking to maintain form and track progress accurately.

FEATURES

FAQs

What are bumper plates used for?

Bumper plates are commonly used in Olympic weightlifting and cross training. They are ideal for movements where the barbell is dropped, such as clean and jerk or snatch, as they protect the barbell and the lifting platform.

How are bumper plates different from traditional iron plates?

Bumper plates are made of rubber, which allows them to be dropped safely without causing damage. Traditional iron plates are not designed for dropping and can damage both the floor and the plates if dropped.

Is there a standard diameter for bumper plates?

The standard diameter of a bumper plate is 450mm (17.72 inches). This is the same diameter as competition-style iron plates, ensuring consistency in the barbell height.

What is the difference between bumper plates and traditional rubber coated plates?

Bumper plates are made from a dense rubber and are specifically designed for Olympic weightlifting movements where the barbell is dropped. Rubber bumper plates are not designed for dropping. Another difference you’ll find is bumper plates all have the same diameter. The diameter of a rubber coated weight plate will generally decrease as the weight decreases.

What is SBR NR Rubber found in your quality bumpers?

SBR NR rubber is known for its excellent durability and resilience, making it well-suited for absorbing impact and withstanding repeated use, which is crucial for bumper plates in weightlifting environments. SBR rubber also has good shock absorption properties, helping to reduce noise and vibration when weights are dropped onto the plates.
