The \u003cstrong\u003eKogel Bottom Bracket BSA to 30mm Gravel\/MTB Seals\u003c\/strong\u003e addresses that directly — reinforced gravel and MTB-spec seals are designed to keep moisture, mud, and trail debris out of the bearing races where standard road-spec units typically don't last. Ceramic bearings keep rolling resistance low and service intervals longer than steel alternatives.\u003c\/p\u003e\n\n\u003cp\u003eThe BSA threaded shell makes this a straightforward fit for the vast majority of gravel and mountain frames on the market. Inside, Kogel's hand-assembled ceramic bearings are built to run consistently over time — not just out of the box. Compatible with 30mm spindle cranks including Easton, Race Face, Zipp, 386EVO, Campagnolo Over Torque, and Rotor. Installation requires a compatible cup tool — the Park Tool BBT-79 is the standard recommendation.\u003c\/p\u003e\n\n\u003ch3\u003eKogel Bottom Bracket BSA to 30mm Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eShell standard: BSA threaded\u003c\/li\u003e\n  \u003cli\u003eSpindle diameter: 30mm\u003c\/li\u003e\n  \u003cli\u003eBearing type: Ceramic\u003c\/li\u003e\n  \u003cli\u003eSeal spec: Gravel\/MTB — reinforced for high-moisture and high-debris conditions\u003c\/li\u003e\n  \u003cli\u003eCompatible cranks: Easton, Race Face, Zipp, 386EVO, Campagnolo Over Torque, Rotor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Kogel","offers":[{"title":"Black","offer_id":43579344420908,"sku":"BSA-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-bsa-to-30mm-gravelmtb-seals-6878155.jpg?v=1771295470","url":"https:\/\/ricycles.com\/products\/kogel-bottom-bracket-bsa-to-30mm-gravel-mtb-seals","provider":"RA Cycles","version":"1.0","type":"link"}
