{"type":"firestarter.listing","listing":{"id":"lst_AFqK-7Pl","product_name":"KG Competition Bumper Plate Sets","category":"Weight Plate","description":"Wickedly precise and boldly colored, the Competition Bumper Plates are the perfect calibrated plates for Olympic lifting.These competition bumper plates don't just look amazing, they also closely align with IWF specs and outperform all-black bumpers. While they're not IWF approved, they do check the key boxes: 450mm diameter, color-coded, and guaranteed to +/- 0.1% of the claimed weight.The galvanized center hub with its co-molded steel collar won't spin or break from the rubber and uses an innovative method to securely lock the bolts in place.All this mumbo-jumbo to say that the hub is safeguarded against loosening and the competition bumper plates will scuff less over time.Unlike our \"pound\" (lbs) version, these comp bumpers DO match IWF specs!But don't let that rain on your parade, they still make excellent training plates for Olympic weightlifting!Version 2.0: Compared to the previous version, these have no center hub bolts and feature a traditional edge inside the plates, making them easier to grab.IMPORTANT: Not IWF approved. The precision-cut 50.5mm center hole might not fit out-of-spec Olympic barbells.","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/140-kg-bccbp-set-thumbnail.jpg?v=1764595070","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/190-kg-bccbp-set-thumbnail.jpg?v=1764595070","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/230-kg-bccbp-set-thumbnail.jpg?v=1764595070","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/240-kg-bccbp-set-thumbnail.jpg?v=1764595070","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/290-kg-bccbp-set-thumbnail.jpg?v=1764595070"],"price":1064.99,"currency":"USD","in_stock":true,"inventory_qty":49995,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.335Z"},"share_url":"https://firestarter.network/l/lst_AFqK-7Pl","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
