It threads directly into T47 frames with an 85.5mm or 86.5mm shell and accepts SRAM DUB cranksets, using \u003cstrong\u003eceramic bearings behind heavy-duty seals\u003c\/strong\u003e designed to block mud, grit, and moisture before they reach the bearing internals.\u003c\/p\u003e\n\n\u003cp\u003eThe gravel and MTB seal spec is a deliberate step up from a road-oriented unit — the kind of distinction that matters after a wet trail descent or a long day in variable conditions. Kogel builds these by hand, and the ceramic bearing assemblies are intended to run with lower friction and greater durability than steel alternatives under sustained load and exposure.\u003c\/p\u003e\n\n\u003ch3\u003eKogel Bottom Bracket T47-I to DUB Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eShell standard: T47 internal (threaded)\u003c\/li\u003e\n  \u003cli\u003eShell width compatibility: 85.5mm or 86.5mm\u003c\/li\u003e\n  \u003cli\u003eSpindle compatibility: SRAM DUB\u003c\/li\u003e\n  \u003cli\u003eBearing type: Ceramic\u003c\/li\u003e\n  \u003cli\u003eSeal spec: MTB\/Gravel — heavy-duty debris and moisture protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Kogel","offers":[{"title":"Black","offer_id":43579494793260,"sku":"T47-iDUB-C","price":279.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/kogel-bottom-bracket-t47-i-to-dub-gravelmtb-seals-4008466.jpg?v=1771295413","url":"https:\/\/ricycles.com\/products\/kogel-bottom-bracket-t47-i-to-dub-gravel-mtb-seals","provider":"RA Cycles","version":"1.0","type":"link"}
