The result is a bottom bracket designed to run smoothly over the long haul — minimizing friction without sacrificing durability. Compatible with 24mm spindle cranksets from Shimano, Rotor, and SRAM GXP, it covers a wide range of common road drivetrain setups.\u003c\/p\u003e\n\n\u003cp\u003eKogel hand-assembles their bottom brackets, and the road seal spec here reflects a deliberate tradeoff: \u003cstrong\u003elighter contact seals\u003c\/strong\u003e that prioritize rolling efficiency over the heavier protection you'd want in wet or muddy conditions. If your riding is primarily on pavement, that's the right call — less seal drag means more of your effort reaches the rear wheel.\u003c\/p\u003e\n\n\u003ch3\u003eKogel BB90 to 24mm Road Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eShell standard: BB90 (Trek carbon frames)\u003c\/li\u003e\n  \u003cli\u003eSpindle compatibility: 24mm — Shimano, Rotor, SRAM GXP\u003c\/li\u003e\n  \u003cli\u003eBearing type: Ceramic\u003c\/li\u003e\n  \u003cli\u003eSeal type: Road seals (low-drag, efficiency-focused)\u003c\/li\u003e\n  \u003cli\u003eConstruction: Hand-assembled\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Kogel","offers":[{"title":"Black","offer_id":43579343241260,"sku":"BB90-24GXP-R","price":164.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/kogel-bottom-bracket-bb90-to-24mm-road-seals-3618651.jpg?v=1771295470","url":"https:\/\/ricycles.com\/products\/kogel-bottom-bracket-bb90-to-24mm-road-seals","provider":"RA Cycles","version":"1.0","type":"link"}
