Competition IWF Certified Kilo Bumper Plates


IWF LogoCompetition bumpers are IWF approved! They are specially fabricated with a blend of kevlar and rubber, designed to absorb heavy use. They are made with 2 tungsten steel center inserts with 5 calibrated screws for precise weight. The weight of the bumper is guaranteed to be within 0.2kg and the diameter (450mm with a tolerance of +/- 1mm). The collar insert is exactly 50.4mm, with a tolerance of +/- 0.1mm. The plates have been given a gloss-matte textured  finish and raised lettering for a bolder look. For coaches and athletes who compete at the international level, these bumpers are the perfect fit.

Competition Series 

Werksan competition bumpers ranks among the best in the industry for feel, durability and performance, that is why we are coach’s and athletes number 1 choice. If you are looking for better performance and explosive power, our competition series can help take you to the next level! All  competition bumper plates come with a 5 year guarantee warranty.


Each bumper is tested for quality assurance; all while maintaining a tough and durable tungsten steel hub finished off with a chrome design. A raised rubber surface helps to prevent direct metal-on-metal contact between the center discs. Whether stacked on the bar or on a rack, the bumpers only come into contact with each other on the inner and outer flanges—reducing scuffing and helping to preserve the plates’ finish and lettering. A convenient lip on the edge of the plate also makes it easier to pick up from the rack or off the ground.
