CeramicSpeed BB Alpha Bottom Bracket – ITA

Performance & Use Case
BB Alpha is designed to outlast the frame it is fitted to. For ITA Italian-threaded framesets, it is the bottom bracket that resists the contamination that typically kills standard alloy bearings within a season. For road, tri and track riders building a long-life ITA 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.

Compatibility
Fits any frameset with an ITA Italian-threaded shell. Two spindle-compatibility options cover Shimano Hollowtech II (24mm) and SRAM DUB (28.99mm) cranksets. Select the variant that matches your crankset. All BB Alpha models are backed by CeramicSpeed’s lifetime warranty.
