Ceramicspeed T47a Shimano bottom bracket

T47a for 77 mm asymmetric housing. The T47a is a threaded bottom bracket housing that utilizes the oversized interface of the right bottom bracket, but with the advantage and security of a threaded connection. Compatible frames have an asymmetric housing width of 77 mm, with the bearing on the non-drive side located inside the frame and the bearing on the drive side positioned outside the frame. Equipped with precision dust caps for a snug and secure fit that fully protects the end of the bearing, it offers exceptional performance without any compromises. CeramicSpeed handmade bearings transfer the load from the crankset to the frame with unmatched durability and efficiency. Details: - Discipline: Road and Tri - Crankset Brand: Shimano - BB Type: T47a.
