The aluminum cups press into your BB30 frame shell, accepting any 24mm\/22.2mm spindle crank — the standard used across SRAM's mountain drivetrain lineup. Inside those cups sit CeramicSpeed's Grade 3 Silicon Nitride balls, pressed into hardened steel races in dust-free clean rooms in Denmark.\u003c\/p\u003e\n\n\u003cp\u003eThe case for ceramic bearings in a mountain bike bottom bracket is straightforward: \u003cstrong\u003elower rolling resistance and significantly longer service life\u003c\/strong\u003e. CeramicSpeed's silicon nitride balls are harder and smoother than standard steel, which means less friction under load and less wear over time — the kind of difference that compounds across long seasons of riding. Available in black or red to suit your build.\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\u003eFitment: BB30 shell to GXP (24mm\/22.2mm) spindle\u003c\/li\u003e\n  \u003cli\u003eShell diameter: 42mm inner diameter (BB30 standard)\u003c\/li\u003e\n  \u003cli\u003eShell width: 73mm\u003c\/li\u003e\n  \u003cli\u003eBearing material: Grade 3 Silicon Nitride ceramic balls in hardened steel races\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":43594071146540,"sku":"101464","price":269.25,"currency_code":"USD","in_stock":true},{"title":"English \/ Red","offer_id":43594071212076,"sku":"101466","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-gxp-sram-5258294.jpg?v=1771294932","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-mtb-bottom-bracket-bb30-to-gxp-sram","provider":"RA Cycles","version":"1.0","type":"link"}
