The \u003cstrong\u003eKogel Bottom Bracket BB86 to 30mm Gravel\/MTB Seals\u003c\/strong\u003e fixes that. Built for BB86 road frames and BB92 MTB frames running 30mm spindle cranks, it pairs ceramic bearings with heavy-duty seals designed specifically for high-contamination conditions — the kind where standard road-spec seals fail quickly.\u003c\/p\u003e\n\n\u003cp\u003eKogel hand-assembles each unit, and the \u003cstrong\u003eceramic bearings\u003c\/strong\u003e are built to maintain consistent, low-friction rotation across a long service life rather than degrading after a season of hard riding. Compatible with most 30mm spindle cranks — including Race Face, Easton, Zipp, 386EVO, and Rotor — though spindle length varies between manufacturers, so it's worth confirming compatibility before fitting.\u003c\/p\u003e\n\n\u003ch3\u003eKogel BB86 to 30mm Gravel\/MTB Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eShell compatibility: BB86 (road) \/ BB92 (MTB)\u003c\/li\u003e\n  \u003cli\u003eSpindle diameter: 30mm\u003c\/li\u003e\n  \u003cli\u003eBearing type: Ceramic\u003c\/li\u003e\n  \u003cli\u003eSeal type: Gravel\/MTB — heavy-duty, high-contamination\u003c\/li\u003e\n  \u003cli\u003eCompatible cranks: Race Face, Easton, Zipp, 386EVO, Rotor (verify spindle length for others)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Kogel","offers":[{"title":"Black","offer_id":43579299135532,"sku":"BB92-30-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-bb86-to-30mm-gravelmtb-seals-6907918.jpg?v=1771295472","url":"https:\/\/ricycles.com\/products\/kogel-bottom-bracket-bb86-to-30mm-gravel-mtb-seals","provider":"RA Cycles","version":"1.0","type":"link"}
