The CeramicSpeed BB ALPHA pairs a\n      24 mm Shimano road crank with a T47\/68 threaded frame — the road-width version\n      of T47 — delivering the lowest-friction, longest-lasting bottom bracket\n      CeramicSpeed has ever made for builders who want the strength of a threaded\n      shell with road geometry.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"product-section\"\u003e\n    \u003ch2\u003eWhy riders choose BB ALPHA\u003c\/h2\u003e\n\n    \u003cdiv class=\"product-feature\"\u003e\n      \u003ch3\u003eGrade-3 Silicon Nitride ceramic balls in hardened stainless-steel races\u003c\/h3\u003e\n      \u003cp\u003e\n        Standard steel bottom brackets develop drag and play after a single wet\n        season, so you end up replacing them every year and losing watts in between.\n      \u003c\/p\u003e\n      \u003cp\u003e\n        The hand-built ceramic bearing system runs ultra-smooth from day one and stays\n        smooth for the life of the frame — you feel less resistance on every pedal\n        stroke and stop budgeting for a yearly bottom bracket swap.\n      \u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"product-feature\"\u003e\n      \u003ch3\u003eCustom seals with 500% better moisture protection\u003c\/h3\u003e\n      \u003cp\u003e\n        Wet rides, washing, and grit are what actually kill bottom brackets — water\n        gets past the seal and the bearing rusts from the inside.\n      \u003c\/p\u003e\n      \u003cp\u003e\n        The redesigned BB ALPHA seal blocks moisture and contamination dramatically\n        better than previous generations, so the bearing keeps spinning quiet and\n        free through winter training, gravel detours, and every post-ride hose-down.\n      \u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"product-feature\"\u003e\n      \u003ch3\u003eSimplified spacer tube + lighter cups, 10% lighter overall\u003c\/h3\u003e\n      \u003cp\u003e\n        Old-style T47 bottom brackets needed a bag of spacers and a service manual to\n        install correctly, and the cups added grams in the worst place on the bike.\n      \u003c\/p\u003e\n      \u003cp\u003e\n        The new design installs in minutes with fewer parts to lose, and you save\n        weight right at the bottom of the drivetrain where it matters for acceleration\n        and climbing response.\n      \u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"product-feature\"\u003e\n      \u003ch3\u003eCustom dust covers refined through 28 design iterations\u003c\/h3\u003e\n      \u003cp\u003e\n        Cheap dust covers pop loose, rattle, or let dirt in — exactly what you don't\n        want on a €10k bike.\n      \u003c\/p\u003e\n      \u003cp\u003e\n        The fitment-optimized covers stay seated and sealed under real road and race\n        use, so the bearing stays clean and you don't hear any creaks or ticks coming\n        from the BB shell.\n      \u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"product-feature\"\u003e\n      \u003ch3\u003eLifetime warranty\u003c\/h3\u003e\n      \u003cp\u003e\n        CeramicSpeed backs every BB ALPHA for life.
