IVANKO OCB Rubber Weightlifting Olympic Plates have a weight error of just 0.3% or less. For example, for a 20kg plate, the error is an astonishing 6g or less. The secret lies in the weight fine-tuning mechanisms in two places. No matter how carefully they are made, the iron parts that make up the weight and the rubber coating alone cannot maintain such weight accuracy. Therefore, pockets are created in the plates, and weights are inserted into them, allowing the weight to be adjusted by hand. (See the weight fine-tuning mechanism in the second image.)\u003c\/p\u003e\n\n\u003cbr\u003e\n\u003ch2 class=\"sttl-006 mt10\"\u003e Rubber coating for peace of mind even if dropped\u003c\/h2\u003e\n\n \u003cp\u003eThese plates are made of the highest quality natural rubber, which is crack-resistant and covered with an extra-thick coating. Since weightlifting competitions often involve dropping plates from high places, these plates are designed to withstand the impact and last a long time. The rubber is also very soft, reducing noise and vibration when dropped.\u003c\/p\u003e\n\n\u003cbr\u003e\n\u003ch2 class=\"sttl-006 mt10\"\u003e All diameters are the same\u003c\/h2\u003e\n\n\u003cp\u003e Since they are designed to be dropped, the diameter size is the same for all weights. If the sizes were different, the load would be placed on the plate with the largest diameter when dropped. If all the diameters were the same, the load would be absorbed by all the plates, dispersing the impact. \u003c\/p\u003e\n\n\u003cbr\u003e\u003cbr\u003e\u003cimg width=\"100%\" src=\"https:\/\/fitnessshop.thinkfitness.jp\/upload\/save_image\/exp\/machine\/exp_iv_platesize.png\" alt=\"IVANKO plate size\"\u003e\n\u003ctable width=\"300\" border=\"0\"\u003e\n\n\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e weight\u003c\/td\u003e\n\n\u003ctd\u003e Thickness\u003c\/td\u003e\n\n\u003ctd\u003e diameter\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e 10kg\u003c\/td\u003e\n\n\u003ctd\u003e 25.4mm\u003c\/td\u003e\n\n\u003ctd\u003e 450.85mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e 15kg\u003c\/td\u003e\n\n\u003ctd\u003e 45.5mm\u003c\/td\u003e\n\n\u003ctd\u003e 450.85mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e 20kg\u003c\/td\u003e\n\n\u003ctd\u003e 57.2mm\u003c\/td\u003e\n\n\u003ctd\u003e 450.85mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e 25kg\u003c\/td\u003e\n\n\u003ctd\u003e 57.2mm\u003c\/td\u003e\n\n\u003ctd\u003e 450.85mm \u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\n\n\n\u003c\/table\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n \u003cp\u003e\u003ca href=\"https:\/\/fitnessshop.live\/pages\/%E3%83%90%E3%83%BC%E3%83%99%E3%83%AB-%E3%83%97%E3%83%AC%E3%83%BC%E3%83%88%E3%81%AE%E9%81%B8%E3%81%B3%E6%96%B9\" target=\"_blank\" title=\"How to choose barbell plates\" rel=\"noopener noreferrer\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/0309\/3831\/files\/49fb1e02615c0054a02c505bc6ce3782_1024x1024.jpg?v=1678337740\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\n\n\u003c\/div\u003e","brand":"フィットネスショップ","offers":[{"title":"10kg","offer_id":39875454107719,"sku":"6012007300010","price":31900.0,"currency_code":"JPY","in_stock":true},{"title":"15kg","offer_id":39875454140487,"sku":"6012007300015","price":40700.0,"currency_code":"JPY","in_stock":true},{"title":"25kg","offer_id":39875454173255,"sku":"6012007300025","price":52800.0,"currency_code":"JPY","in_stock":true},{"title":"20kg","offer_id":39875454206023,"sku":"6012007300020","price":47300.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/0309\/3831\/products\/iv_ocb_l.jpg?v=1666256162","url":"https:\/\/fitnessshop.live\/en\/products\/601200730","provider":"フィットネスショップ","version":"1.0","type":"link"}
