Chris King ThreadFit 30 Bottom Bracket

Built on the familiar BSA threading, the Chris King ThreadFit 30 is ready. A silky smooth, long-lasting bottom bracket built around our angular contact bearings that wear in instead of out. The ThreadFit30 is made for 30mm spindles.

Fully serviceable and backed by our 5-year built-to-last warranty this bottom bracket will outlast your bike. Built to ultra-tight aerospace tolerances we use machined Delrin spindle sleeves to create a perfect, and precise, fit between cranks and frame, providing ultra-low drag, and a butter smooth feel. With a large range of conversion kits our ThreadFit30 is ready for a wide selection of cranks.
