Thanks to this passion, Ashima produce the MTB and Road products of the highest quality level. The rigorous tests used for the quality assurance of materials meet all EN standards. \u003c\/p\u003e\n\u003cp\u003eIn order to guarantee the effectiveness and reliability of Ashima products, its team have created a specific testing machine, used in the automotive industry also, where the disc is driven around its axis of rotation and the stress loads are applied by pneumatic cylinders, controlled by computer, thus eliminating the variables on the tests applied on the complete bicycle. In addition to in-house testing, Ashima uses field-tests made professional athletes.\u003c\/p\u003e\n\u003ch2\u003e\n\u003cbr\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 piece construction.\u003c\/li\u003e\n\u003cli\u003eMounting type: 6 bolts.\u003c\/li\u003e\n\u003cli\u003eTightening torque: 10-12 Nm (88.5 - 106.2 lbs)(5 mm Allen key).\u003c\/li\u003e\n\u003cli\u003eMaterial: hardened stainless steel.\u003c\/li\u003e\n\u003cli\u003eRockwell hardness index: 47 (HRC).\u003c\/li\u003e\n\u003cli\u003eCompatibility: all disc brake systems and 6 bolts hubs.\u003c\/li\u003e\n\u003cli\u003eManufacturer weight: 106 g (160 mm).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n\u003cbr\u003eTechnologies\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eRockwell\u003c\/strong\u003e\u003cbr\u003eThe Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. In other words: the hardness is determined on a basis of the elasto-plastic deformation of a material under the test.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHRC: the indenter is a diamond cone with a 120° opening angle and a 0.2 mm radius. This method is usually used for very hard materials with HB\u0026gt;200 Brinell hardness value.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBrinell\u003c\/strong\u003e\u003cbr\u003eIn order to obtain the hardness index, high pressure is applied on a material, using an indenter. Then the mark diameter, left by the material, shows a necessary value. This test is standardized by international standards in order to guarantee the comparability of hardness values for a correct evaluation of the material characteristics. In particular, this test is regulated by the ASTM E10-17 standard and Standard Test Method for Brinell Hardness of Metallic Materials.\u003c\/p\u003e\n\u003cp\u003eThe Brinell method provides the possibility of using two different penetrators: hardened steel and hard metal, such as tungsten carbide. Both penetrators are spherical in shape. The hardened steel penetrator test is generally considered reliable when the final value is less than 350, and 650 if the carbide penetrator is used.\u003c\/p\u003e\n\u003ch2\u003e\n\u003cbr\u003eIncluded\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e6x mounting bolts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n\u003cbr\u003eNot included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAllen key.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ashima","offers":[{"title":"Neutral \/ 160 mm","offer_id":48058019152113,"sku":"305502040","price":12.83,"currency_code":"AUD","in_stock":true},{"title":"Neutral \/ 180 mm","offer_id":48058019184881,"sku":"305502045","price":15.4,"currency_code":"AUD","in_stock":true},{"title":"Black \/ 160 mm","offer_id":48058019217649,"sku":"305502050","price":15.4,"currency_code":"AUD","in_stock":true},{"title":"Black \/ 180 mm","offer_id":48058019250417,"sku":"305502060","price":19.38,"currency_code":"AUD","in_stock":true},{"title":"Red \/ 180 mm","offer_id":48058019283185,"sku":"305502065","price":17.97,"currency_code":"AUD","in_stock":true},{"title":"Red \/ 160 mm","offer_id":48058019315953,"sku":"305502055","price":16.69,"currency_code":"AUD","in_stock":true},{"title":"Neutral \/ 203 mm","offer_id":48058019348721,"sku":"305502205","price":17.97,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1580\/4145\/files\/zm_20190114-014759.jpg?v=1776527479","url":"https:\/\/novasportsbikes.com\/products\/ashima-aro-19-disc-rotor-1","provider":"Nova Sports Bikes","version":"1.0","type":"link"}
