It is set to an optimal depth to ensure a firm grip, and to prevent sharp edges from hurting your hands. Similar to the depth, we also paid particular attention to the shape of the knurling, which has a significant impact on gripping ease, and designed the barbell to provide a firm grip.\u003cbr\u003e Furthermore, by working with manufacturers and factories to control quality by taking these points into consideration, we aimed to create a barbell that is affordable yet allows for effective training. \u003c\/p\u003e\n\n\u003ch2\u003e\u003cimg style=\"width: 100%;\" src=\"https:\/\/fitnessshop.thinkfitness.jp\/user_data\/img\/ibs_2.jpg\" alt=\"The barbell collar \u0026quot;CL1\/4\u0026quot;, packed with IVANKO's know-how, is included as standard.\"\u003e\u003c\/h2\u003e\n\n \u003cp align=\"LEFT\"\u003eThe barbell collar \"CL 1\/4,\" packed with IVANKO's expertise, is included as standard. The popular \"CL 1\/4\" barbell collar, which many customers purchase separately, features a mechanism whereby a pressure ring inside the collar tightens when the screw is turned, securing the shaft with the pressure ring (surface) rather than the screw (point). The benefits of securing with a \"surface\" rather than a \"point\" are numerous, including increased holding power, less damage to the shaft, and less peeling of the shaft's anti-rust coating (typically chrome plating). This exceptional product was designed with the risk of rust weakening the steel and ultimately shortening the barbell's lifespan in mind. \u003c\/p\u003e\n\n\u003cp\u003e\u003cimg style=\"width: 100%;\" src=\"https:\/\/fitnessshop.thinkfitness.jp\/user_data\/img\/ib-pr.jpg\" alt=\"IVANKO's unique pressure ring mechanism for fixing force\"\u003e\u003c\/p\u003e\n\n\u003ch2\u003e\u003cimg style=\"width: 100%;\" src=\"https:\/\/fitnessshop.thinkfitness.jp\/user_data\/img\/ibs_4.jpg\" alt=\"Which is better, φ28mm or φ50mm?\"\u003e\u003c\/h2\u003e\n\n \u003cp align=\"LEFT\"\u003eBarbell shafts come in several different diameters for the sleeves (the part where the plates are attached), and those with a diameter of 50mm are commonly called \"Olympic shafts\" or \"Olympic plates,\" and are the type commonly used in gyms.\u003cbr\u003e On the other hand, there are various standards for home training equipment around the world, but in Japan, the standard is often 28mm in diameter, and this product is of that 28mm.\u003cbr\u003e There are some differences between manufacturers, but generally speaking, there are the following differences between the two:\u003c\/p\u003e\n\n\u003cp align=\"LEFT\"\u003e \u003cb\u003ePriceφ50mm\u003c\/b\u003e : tends to be expensiveφ28mm: can be reasonably priced\u003c\/p\u003e\n\n \u003cp align=\"LEFT\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e : φ50mm sleeve contains bearings and bushings, allowing the sleeve to rotate.
