CeramicSpeed T47a Shimano bottom bracket, black
T47a for 77 mm asymmetric shell. The T47a is a threaded center console shell design that utilizes the oversized interface of a true BB, but with the convenience and peace of mind of a threaded interface. Compatible frames feature an asymmetrical 77mm shell width, with the non-drive side bearing located inside the frame and the drive side bearing located externally. Equipped with precision dust caps for a comfortable and secure fit, which also fully protects the bearing face, it delivers exceptional performance without any sacrifices. Hand-crafted CeramicSpeed bearings transfer the load from the crank to the frame with unmatched durability and efficiency.
