CeramicSpeed BB ALPHA BSA Bottom Bracket for 24MM Road
The CeramicSpeed BB ALPHA BSA Bottom Bracket for 24MM Road is built for BSA 68 mm shells and 24 mm crank spindles. The BB ALPHA provides up to 500% better moisture protection and keeps the signature low-friction feel CeramicSpeed delivers. The new BB ALPHA design is also lighter, cutting weight by 10% compared to previous generations. CeramicSpeed’s premium ceramic ball bearings sit at the core of the system. These bearings cut drag by an average of 75% compared to standard bottom brackets. CeramicSpeed hand-assembles each BB ALPHA in Holstebro, Denmark to ensure exceptional precision and quality and they back every unit with a lifetime warranty.
Key Features
- Lightweight Design: A simplified spacer tube, lighter cups and the ceramic bearings make this a very lightweight bottom bracket.
- Robust Sealing: Custom engineered seals and dust covers offer outstanding protection from water and dirt.
- Low Friction: CeramicSpeed has been in the business of ceramic ball bearings since the 90s, and their proprietary Silicon Nitride balls are 100% smoother and 15% harder than other ceramic bearings. In addition this bottom bracket uses a road-specific grease, further reducing drag.
- Lifetime Warranty: CeramicSpeed builds the BB ALPHA to such a high standard that they back it with a lifetime warranty.
