For BB86 press-fit framesets, it is the bottom bracket that resists the contamination from water, grit and dust that typically kills standard alloy bearings within a season. For road, tri and track riders building a long-life BB86 frameset, it is the bottom bracket that won't be the weak link.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eConstruction \u0026amp; Materials\u003c\/strong\u003e\u003cbr\u003e\nEach BB Alpha unit features hardened stainless steel races hand-built with grade 3 Silicon Nitride ceramic balls. Custom-engineered seals and precision dust covers together provide up to 500% better moisture protection than standard bottom brackets, while still maintaining ultra-low friction. A simplified spacer tube design and lighter cups give a 10% weight saving over previous BB Alpha generations and make installation quicker.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003cbr\u003e\nFits any frameset with a BB86 press-fit shell - 41mm bore, 86mm width.
