CeramicSpeed Race Coated T47A-to-Shimano Bottom Bracket

Description

The CeramicSpeed Race Coated Bottom Bracket – T47a to Shimano is built for frames with a 77mm asymmetric T47A shell — a spec found on certain high-end road frames — and brings CeramicSpeed’s coated bearing race treatment to a Shimano-compatible interface. The coating is designed to harden the races against wear, reducing friction and extending service intervals compared to standard uncoated bearings.

T47 threading means you get a secure, rattle-free fit without the long-term headaches that press-fit designs can introduce. If you’re putting serious miles into a T47A-equipped frame and running Shimano cranks, this is a direct, low-maintenance upgrade to your drivetrain’s most foundational connection.
