At the core are grade-3 Silicon Nitride ceramic balls hand-built into hardened stainless-steel races. These aren't pressed into generic cups — each unit is assembled to CeramicSpeed's exacting tolerances, which is why the brand backs every BB ALPHA with a lifetime warranty.\u003c\/p\u003e\n\n  \u003cp\u003eThe gravel-specific designation matters. CeramicSpeed redesigned the dust covers through 28 iterations of development to nail the fitment, and the custom-engineered seals deliver 500% better moisture protection than conventional bottom brackets. That protection comes without trading away the ultra-low friction that makes ceramic bearings worth the investment in the first place. The updated cup design and simplified spacer tube also bring a 10% weight reduction over the previous BB ALPHA generation. Each unit ships with a sample of CeramicSpeed's UFO TECH Long Life Bearing Grease; the SRAM DUB version includes a DUB Spacer Kit.\u003c\/p\u003e\n\n  \u003ch3\u003eSpecs at a Glance\u003c\/h3\u003e\n  \u003cul class=\"specs_at_a_glance\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShell:\u003c\/strong\u003e BSA English Threaded, 68mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBearings:\u003c\/strong\u003e Grade-3 Silicon Nitride ceramic balls, hardened stainless-steel races\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMoisture protection:\u003c\/strong\u003e 500% better than standard, via custom seals and precision dust covers\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano (24mm spindle), SRAM DUB (28.99mm spindle), 30mm spindle\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWeight (Shimano):\u003c\/strong\u003e 81g | \u003cstrong\u003eWeight (SRAM DUB):\u003c\/strong\u003e 87g\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Lifetime\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIn the box:\u003c\/strong\u003e BB ALPHA, UFO TECH Long Life Bearing Grease 5ml, decal (SRAM DUB adds DUB Spacer Kit)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Shimano","offer_id":45446051561516,"sku":"115518","price":449.0,"currency_code":"USD","in_stock":true},{"title":"SRAM DUB","offer_id":45446051594284,"sku":"115519","price":449.0,"currency_code":"USD","in_stock":true},{"title":"30mm","offer_id":45446051627052,"sku":"115520","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-bb-alpha-road-bsa-threaded-5267429_7b588275-16b4-4717-936d-305c83894cdc.jpg?v=1775849959","url":"https:\/\/racycles.com\/pt\/products\/ceramicspeed-bb-alpha-gravel-bsa-threaded","provider":"RA Cycles","version":"1.0","type":"link"}
