The \u003cstrong\u003eCeramicSpeed Ceramic Wheel Kits - Zipp 4\u003c\/strong\u003e is a six-bearing replacement kit designed for Zipp wheels running 88 front and 188 v9 rear hubs — giving you a complete upgrade in a single box. The Grade 3 Silicon Nitride ceramic balls are installed into hardened steel races in dust-free clean rooms, with CeramicSpeed's own low-friction grease included from the factory.\u003c\/p\u003e\n\n\u003cp\u003eThe numbers behind the balls are worth knowing: compared to standard steel, they're tested at 400% smoother, 128% harder, and 58% lighter. Against standard ceramic balls, they still outperform — over 100% smoother and 15% harder. The practical result is \u003cstrong\u003ebearing life rated at three to five times longer than standard\u003c\/strong\u003e alongside measurably lower rolling resistance. The kit includes two bearings for the front hub, two for the rear hub, and two for the cassette body, plus seals, grease, and a grease syringe for installation.\u003c\/p\u003e\n\n\u003ch3\u003eCeramicSpeed Ceramic Wheel Kits - Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eCompatible with Zipp 88 front and 188 v9 rear hubs\u003c\/li\u003e\n  \u003cli\u003eSix bearings per kit — front hub (x2), rear hub (x2), cassette body (x2)\u003c\/li\u003e\n  \u003cli\u003eGrade 3 Silicon Nitride ceramic balls in hardened steel races\u003c\/li\u003e\n  \u003cli\u003eAssembled in dust-free clean rooms with CeramicSpeed proprietary grease\u003c\/li\u003e\n  \u003cli\u003eIncludes seals, grease, grease syringe, and sticker sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":43705649922092,"sku":"101746","price":630.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-ceramic-wheel-kits-zipp-4-9072162.jpg?v=1771301647","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-wheel-kits-zipp-4","provider":"RA Cycles","version":"1.0","type":"link"}
