Chris King ThreadFit T47A 30 Ceramic Bottom Bracket

Chris King ThreadFit T47A 30 Ceramic Bottom Bracket is a threaded T47A bottom bracket for cranks with a 30mm spindle. It has a 47mm housing diameter and uses Chris King's ceramic bearings, which Chris King describes as built for low friction and long service life. The ThreadFit design is meant to keep the security of a threaded shell, which helps reduce the creaking that can plague pressed-in bottom brackets.

The T47A version is listed for road, triathlon and time trial frames. Chris King machines and assembles its components in Portland, Oregon, and the ceramic option is the brand's upgrade over its standard bearings. It comes in ten colors, including Red, Silver, 3D Violet, Black, Matte Black, Matte Gold 50th, Matte Jade, Matte Mango, Matte Turquoise and Midnight, so it can match a Chris King headset or hubs. Check that your frame is specified for the T47A before ordering, since it is not interchangeable with a standard T47 bracket.
