This is the Chris King ThreadFit T47-24x bottom bracket in black/gold two-tone, for T47 24x and 24i shells running 24mm-spindle cranksets. The precision bearings are made in-house, and Fit Kits 4 and 6 adapt the unit to specific cranks.
It solves the creak-prone big-shell problem on modern gravel and road frames — T47 threads in like a classic BB while keeping the oversized shell’s stiffness, and the King bearings handle wet seasons without complaint.
Chris King Precision Components has machined bicycle components in Portland, Oregon since 1976, making its own bearings from domestic-mill materials and anodizing parts in-house.
