Grade 3 Silicon Nitride ceramic balls are pressed into hardened steel races in dust-free clean rooms — a process designed to produce bearings that are measurably smoother, harder, and lighter than the steel bearings found in standard bottom brackets. The result is a bottom bracket that, according to independent friction testing, produces just 0.45 watts of frictional loss.\u003c\/p\u003e\n\n\u003cp\u003eCeramic bearings are the reason pro teams seek out CeramicSpeed — not for the marginal gains narrative, but because durability backs up the speed claims. CeramicSpeed's Grade 3 Silicon Nitride balls are designed to last three to five times longer than conventional steel bearings, meaning fewer replacements and more consistent performance over time. Available in English and Italian threading, with the 24mm spindle interface for Shimano cranksets, this bottom bracket fits directly into standard threaded frames with no adapters required.\u003c\/p\u003e\n\n\u003ch3\u003eCeramicSpeed Ceramic Race Bottom Bracket Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterface:\u003c\/strong\u003e Threaded — English or Italian threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle diameter:\u003c\/strong\u003e 24mm (Shimano-compatible)\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\u003eFrictional loss:\u003c\/strong\u003e 0.45 watts (per independent friction testing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariants:\u003c\/strong\u003e English\/Black, Italian\/Black, Italian\/Red\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"English \/ Black","offer_id":43594070360108,"sku":"101307","price":284.25,"currency_code":"USD","in_stock":false},{"title":"Italian \/ Black","offer_id":43594070392876,"sku":"101323","price":284.25,"currency_code":"USD","in_stock":false},{"title":"Italian \/ Red","offer_id":43594070425644,"sku":"101325","price":284.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-ceramic-race-bottom-bracket-threaded-to-24mm-shimano-9818415.jpg?v=1771294989","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-race-bottom-bracket-threaded-to-24mm-shimano","provider":"RA Cycles","version":"1.0","type":"link"}
