CeramicSpeed T47A 30mm Coated Bottom Bracket for 77mm Asymmetrical Shell Frames

The CeramicSpeed T47A 30mm Coated Bottom Bracket is engineered to deliver exceptional performance and durability for cyclists seeking precision and efficiency. Designed specifically for frames with a 77mm asymmetrical shell, this bottom bracket combines the oversized interface benefits of a BB right with the reliability and peace of mind of a threaded connection. Its unique design places the non-drive side bearing within the frame while situating the drive side bearing externally, ensuring optimal load distribution and enhanced power transfer.

Equipped with precision dust covers, the T47A bottom bracket ensures a secure fit that fully protects the bearing faces from contaminants, maintaining smooth operation throughout the ride. The CeramicSpeed hand-built bearings, crafted from hardened steel races and superior ceramic balls, provide unparalleled durability and reduce drag dramatically. With the CeramicSpeed coating, these bearings offer an even longer lifespan and lower friction, enhancing your cycling experience with less maintenance and sustained performance.

Installation is straightforward with the CeramicSpeed Dual Socket Tool T45/T47, designed specifically for this model. Included in the package are all necessary components such as two cups with bearings and dust covers, a two-part spacer tube, CeramicSpeed All Round Grease, setup spacers, and a sticker sheet, giving you everything needed for a precise and secure setup. Whether you’re upgrading your current bottom bracket or building a new bike, the T47A 30mm Coated Bottom Bracket stands out as a high-quality choice for reliable transmission performance.

What It’s Good For
