Pressed into aluminum cups, CeramicSpeed's Grade 3 Silicon Nitride ceramic balls are seated in hardened steel races and assembled in dust-free clean rooms in Denmark, resulting in a bottom bracket designed to outlast standard bearings by three to five times.\u003c\/p\u003e\n\n\u003cp\u003eThe ceramic balls themselves are the reason riders seek out CeramicSpeed. Compared to standard steel balls, they're \u003cstrong\u003e400% smoother, 128% harder, and 58% lighter\u003c\/strong\u003e — and they outperform standard ceramic balls too, measuring over 100% smoother and 15% harder. Less friction under load means more of your power reaches the trail, and reduced wear means fewer service intervals. Compatible with Shimano 24mm-spindle cranks, this unit fits 73mm-wide BB30 shells with a 42mm inner diameter.\u003c\/p\u003e\n\n\u003ch3\u003eCeramicSpeed Ceramic MTB Bottom Bracket Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eStandard: BB30 shell (42mm inner diameter, 73mm width)\u003c\/li\u003e\n  \u003cli\u003eSpindle compatibility: 24mm (Shimano MTB)\u003c\/li\u003e\n  \u003cli\u003eBearing type: Grade 3 Silicon Nitride ceramic balls in hardened steel races\u003c\/li\u003e\n  \u003cli\u003eCup material: Aluminum\u003c\/li\u003e\n  \u003cli\u003eAvailable colors: Black, Red\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"English \/ Black","offer_id":43594070917164,"sku":"101460","price":269.25,"currency_code":"USD","in_stock":true},{"title":"English \/ Red","offer_id":43594070949932,"sku":"101462","price":269.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-ceramic-mtb-bottom-bracket-bb30-to-24mm-shimano-8950224.jpg?v=1771294932","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-mtb-bottom-bracket-bb30-to-24mm-shimano","provider":"RA Cycles","version":"1.0","type":"link"}
