It contains two 61903 bearings with an internal diameter of 17 mm, an external diameter of 30 mm and a width of 7 mm. These are ceramic bearings, to choose when you need to replace the bearings in a compatible rear hub.\u003c\/p\u003e\n\u003cp\u003eBefore ordering, check the hub version: the kit is listed for the 188 V9 and the 30 and 60 rear hubs, while the 188 V8 is not listed. Compare the 17 mm internal diameter and 7 mm width with the bearings you are replacing. This helps you avoid ordering an incompatible kit.\u003c\/p\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eType\u003c\/th\u003e\n\u003ctd\u003eCeramic bearings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eContents\u003c\/th\u003e\n\u003ctd\u003e61903\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eInternal Diameter\u003c\/th\u003e\n\u003ctd\u003e17 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eExternal Diameter\u003c\/th\u003e\n\u003ctd\u003e30 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eWidth\u003c\/th\u003e\n\u003ctd\u003e7 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCompatibility\u003c\/th\u003e\n\u003ctd\u003e30 and 60 rear hubs; 188 (V9) rear hub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Zipp","offers":[{"title":"Default Title","offer_id":57642956358012,"sku":"605000005","price":264.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/2051\/6162\/files\/supplier-d429091ecaa9bfaaa23bb32d1f1f5cb8bebc64b99d0b7dc5dd265fa01cb1c838.jpg?v=1792605633","url":"https:\/\/evolutionbikes.it\/en-int\/products\/kit-cuscinetti-ceramici-zipp-61903","provider":"Evolution Bikes IT","version":"1.0","type":"link"}
