Competition Bumper Plates – Uncompromising Performance on the Platform Thanks to a design refined down to the last detail, our Competition Bumper Plates deliver an outstanding, no-compromise lifting experience on the platform. Equipped with durable steel disc inserts and a slightly raised rubber lip, the plates can be loaded onto the barbell without direct metal-to-metal contact. The 50.5 mm collar opening ensures a secure fit on the bar and prevents the plates from sliding. Their compact construction results in a minimal bounce effect, making them ideal for high-rep Olympic lifting. Featuring the traditional IWF-standard colour coding and a uniform 450 mm diameter for quick identification and easy handling, Strength Shop’s Competition Bumper Plates are built for both competition and serious training. Specifications: Weight tolerance: +/- 0.1 – 0.05% Finish: matte Material: urethane rubber with a steel core Collar opening: 50.5 mm Diameter: 450 mm Colour coding according to Olympic Weightlifting standards 10 kg: Green / 31 mm thick 15 kg: Yellow / 41 mm thick 20 kg: Blue / 53.5 mm thick 25 kg: Red / 67 mm thick Please note: Plates are sold as singles. 140kg set consists of two of each plate.To protect quality during shipping, our bumper plates are coated with a silicone-based protective film, packed in plastic wrap, and boxed. This may result in a strong rubber smell upon unpacking, which will dissipate over time with regular use. In a well-ventilated gym space, the smell should fade within a few days. To speed up the process, you can clean the plates with water and soap, wipe them down with a cloth, and let them air out.
