The CeramicSpeed BB ALPHA for BBright Shimano Road is built for riders who want the highest level of drivetrain efficiency and long-term reliability. Designed specifically for BBright frames with an asymmetric 46mm pressfit shell and 79mm shell width, it pairs perfectly with Shimano and other 24mm spindle road cranksets for a precise and stable interface.
At its core, hardened stainless-steel bearing races are matched with Grade 3 Silicon Nitride ceramic balls, delivering CeramicSpeed’s signature ultra-low friction while significantly improving resistance to corrosion, contamination, and wear. A custom-engineered sealing system and precision dust covers further enhance protection against water and dirt by up to 500%, ensuring smooth performance in a wide range of riding conditions.
The next-generation BB ALPHA platform also introduces lighter cup construction and a simplified spacer tube design, reducing weight by 10% over previous generations while making installation faster and more intuitive. Handbuilt in Denmark and backed by a lifetime warranty, this is a premium bottom bracket engineered to outlast your frame.
