{"type":"firestarter.listing","listing":{"id":"lst_C018BhBR","product_name":"Urethane Bumper Plate Sets","category":"Weight Plate","description":"If you want bragging rights for having the nicest plates on the block, then these Urethane Bumper Plates are a must-have.Due to the properties of urethane, colours have more \"pop\" to them. This makes lettering and numbers appear crisper, adding a noticeable level of professionalism that'll make others go \"DAAAAAMNN!\" Urethane is also a much harder material than rubber, so these urethane bumper plates are a huge step above the durability of rubber bumpers - even our competition bumper plates can't match their toughness.While they're not IWF-approved, they do check the key boxes with their 450mm diameter and colour-coding. The thing is, they're made in pounds instead of kilograms because, well, #freedomunits. But, don't let that rain on your parade, they still make excellent training plates for Olympic weightlifting with their +/-1% weight tolerance.IMPORTANT: Not IWF approved. Due to its smaller size, the 10lb urethane bumper plate does not have the same reinforced chrome insert as the 25-55lb plates.","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/URE-BP-PRNT-carousel-primary_1ed68d11-ee0c-4bc4-a2be-c5ceab9971a7.jpg?v=1764590682","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/URE-BP-PRNT-carousel-8_a2fd1933-9405-4b3b-948e-ea3af93dec2c.jpg?v=1764590682","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/210-URE-BP-SET-carousel-primary.jpg?v=1764590682","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/300-URE-BP-SET-carousel-primary.jpg?v=1764590682","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/320-URE-BP-SET-carousel-primary.jpg?v=1764590682","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/340-URE-BP-SET-carousel-primary.jpg?v=1764590682"],"price":913.89,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.458Z"},"share_url":"https://firestarter.network/l/lst_C018BhBR","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
