Chris King ThreadFit T47 30i Ceramic Bottom Bracket

The Chris King ThreadFit T47 30i Ceramic Bottom Bracket combines the strength of the modern T47 threaded interface with Chris King’s renowned bearing precision and durability. Built for riders who demand exceptional drivetrain performance and long-term reliability, this bottom bracket integrates premium materials and meticulous machining to deliver smooth pedaling efficiency across countless miles.

The T47 standard blends the stiffness benefits of oversized bottom bracket shells with the reliability of a threaded interface. The ThreadFit T47 30i design installs securely into frames that feature an internal T47 threaded bottom bracket shell, helping eliminate creaks while maintaining a strong and stable connection between the frame and crankset. This system offers the confidence of threaded installation while accommodating modern frame designs built around wider bottom bracket shells.

At the heart of the system are Chris King Ceramic bearings, engineered for extremely low friction and exceptional longevity. These bearings are paired with hardened races and precision-machined components to maintain smooth rotation even in demanding riding environments. The ceramic bearing system reduces drag while maintaining the durability required for high-performance road and gravel riding.

Like all Chris King bottom brackets, the ThreadFit T47 30i is designed with serviceability and long-term performance in mind. Precision-machined cups house the bearings securely while allowing maintenance and bearing service over time. This approach ensures that the bottom bracket continues to perform at a high level long after installation.

Manufactured in the USA with Chris King’s signature attention to detail, this bottom bracket represents a premium solution for modern performance bikes running 30mm spindle cranksets.
