Performance & Use Case
BB Alpha is designed to outlast the frame it is fitted to. 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.
Construction & Materials
Each 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.
Compatibility
Fits any frameset with a BB86 press-fit shell - 41mm bore, 86mm width. Three spindle-compatibility options cover the major crankset standards: Shimano Hollowtech II (24mm), SRAM DUB (28.99mm) and Rotor/FSA (30mm). Select the variant that matches your crankset. All BB Alpha models are backed by CeramicSpeed's lifetime warranty.
