REP’s bumpers have low bounce, which means more control over the barbell when it hits the ground.\n\nThe Color Bumper Plates are durable and factory tested to withstand more than 12,000 drops from an 8-foot height. The 5kg plates are made extra thick to increase durability and reduce bending, while the 20kg plates are thinner than most to allow lifters to fit more plates on the bar (you can fit five 20kg plates and one 10kg plate on each side of a barbell, or 220kg total). Plates are colored per International Weightlifting Federation standards, so you can quickly determine the weight. \u003c\/p\u003e\n\n\u003ch3\u003ePRODUCT DIMENSIONS\u003c\/h3\u003e\n\u003ctable class=\"spec\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003eThickness\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e5 kg\u003c\/td\u003e\n\u003ctd\u003e450 mm\u003c\/td\u003e\n\u003ctd\u003e25.4 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e10 kg\u003c\/td\u003e\n\u003ctd\u003e450 mm\u003c\/td\u003e\n\u003ctd\u003e45.7 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e15 kg\u003c\/td\u003e\n\u003ctd\u003e450 mm\u003c\/td\u003e\n\u003ctd\u003e60.9 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e20 kg\u003c\/td\u003e\n\u003ctd\u003e450 mm\u003c\/td\u003e\n\u003ctd\u003e71.1 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e25 kg\u003c\/td\u003e\n\u003ctd\u003e450 mm\u003c\/td\u003e\n\u003ctd\u003e81.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable class=\"spec\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eRubber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTolerance\u003c\/td\u003e\n\u003ctd\u003e+-1 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"REP Fitness","offers":[{"title":"5kg Pair","offer_id":44611791454436,"sku":"BP-3500-05","price":11900.0,"currency_code":"JPY","in_stock":true},{"title":"10kg Pair","offer_id":44611791487204,"sku":"BP-3500-10","price":16900.0,"currency_code":"JPY","in_stock":true},{"title":"15kg Pair","offer_id":44611791519972,"sku":"BP-3500-15","price":20900.0,"currency_code":"JPY","in_stock":true},{"title":"20kg Pair","offer_id":44611791552740,"sku":"BP-3500-20","price":24900.0,"currency_code":"JPY","in_stock":true},{"title":"25kg Pair","offer_id":44611791585508,"sku":"BP-3500-25","price":29900.0,"currency_code":"JPY","in_stock":true},{"title":"90kg Set","offer_id":44611791618276,"sku":"BP-3500-90","price":61900.0,"currency_code":"JPY","in_stock":false},{"title":"110kg Set","offer_id":44611791651044,"sku":"BP-3500-110","price":70900.0,"currency_code":"JPY","in_stock":false},{"title":"120kg Set","offer_id":44611791683812,"sku":"BP-3500-120","price":74900.0,"currency_code":"JPY","in_stock":false},{"title":"140kg Set","offer_id":44611791716580,"sku":"BP-3500-140","price":91900.0,"currency_code":"JPY","in_stock":false},{"title":"150kg Set","offer_id":44611803414756,"sku":"BP-3500-150","price":102900.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/0376\/6500\/files\/20kg_748c90f8-f7ef-4a97-bb8c-b30accd909c2.jpg?v=1707966246"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/0376\/6500\/collections\/Shopify-Comp-KG-25-Thumbnail_59e9a977-348e-4724-8de3-9247122d475d.jpg?v=1743653330","url":"https:\/\/uchinogym.live\/en\/collections\/bumper-plates.oembed","provider":"ウチノジム","version":"1.0","type":"link"}
