Ceramic Grade 3 Silicon Nitride balls — reported to be 400% smoother, 128% harder, and 58% lighter than conventional steel balls — sit inside aluminum cups machined by Rotor in Spain and assembled at CeramicSpeed in Denmark. That combination of precision manufacturing and ceramic ball quality is what makes this a bearing system the professional peloton actively seeks out.\u003c\/p\u003e\n\n\u003cp\u003eThe PF30 standard uses a 46mm shell diameter, which allows the bearing cups to press directly into the frame without snap rings — a cleaner, more serviceable design than older press-fit standards. The cups here are aluminum, pressed into aluminum sleeves, keeping the assembly light and dimensionally consistent. Available in Black or Red, so it can sit quietly inside the frame or make a statement if your setup calls for it.\u003c\/p\u003e\n\n\u003ch3\u003eCeramicSpeed Ceramic Race Coated Bottom Bracket Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e PF30 frame shell, 24mm spindle cranks (Shimano)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing material:\u003c\/strong\u003e Grade 3 Silicon Nitride ceramic balls in hardened steel races\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCup material:\u003c\/strong\u003e Precision-machined aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShell standard:\u003c\/strong\u003e PF30 (46mm diameter, 68mm width)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable colours:\u003c\/strong\u003e Black, Red\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Black","offer_id":43509528297516,"sku":"101380","price":359.25,"currency_code":"USD","in_stock":true},{"title":"Red","offer_id":43509528330284,"sku":"101383","price":359.25,"currency_code":"USD","in_stock":true}],"url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-race-coated-bottom-bracket-pf30-to-24mm-shimano","provider":"RA Cycles","version":"1.0","type":"link"}
