The \u003cstrong\u003eCeramicSpeed Ceramic MTB Bottom Bracket - Threaded to 24mm (Shimano)\u003c\/strong\u003e addresses that directly, pairing Grade 3 Silicon Nitride ceramic balls with hardened steel races in a threaded external cup design built for 73mm English-threaded shells and 24mm-spindle cranks.\u003c\/p\u003e\n\n\u003cp\u003eThose ceramic balls aren't a marginal upgrade. CeramicSpeed's Grade 3 Silicon Nitride balls are manufactured to a surface finish and roundness specification that results in dramatically lower rolling resistance than standard steel — and significantly better than generic ceramic balls. They're assembled into the races in dust-free clean rooms, with the aluminum cups machined to tight tolerances and the bearings pressed in at CeramicSpeed's facility in Denmark. The result is a bottom bracket designed to last three to five times longer than conventional bearings, not just spin faster.\u003c\/p\u003e\n\n\u003cp\u003eThe threaded BSA external cup format means installation and removal follow the same process as a standard external bottom bracket — a traditional cup tool does the job. Available in black or \u003cstrong\u003ered anodized finish\u003c\/strong\u003e, both in English threading to suit the vast majority of mountain bike frames.\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: BSA threaded external (English threading)\u003c\/li\u003e\n  \u003cli\u003eShell width: 73mm\u003c\/li\u003e\n  \u003cli\u003eSpindle compatibility: 24mm (suits Shimano cranks)\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":43594070622252,"sku":"101448","price":269.25,"currency_code":"USD","in_stock":true},{"title":"English \/ Red","offer_id":43594070655020,"sku":"101450","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-threaded-to-24mm-shimano-4895062.jpg?v=1771294989","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-mtb-bottom-bracket-threaded-to-24mm-shimano","provider":"RA Cycles","version":"1.0","type":"link"}
