New for 2021 is Chris King's first two-tone, anodized, matte-finished black/gold. The finish is so beautiful that the gold logo stands out in all its glory.

The ThreadFit T47 24i and 30i in Two Tone Black/Gold are no longer in production.

ThreadFit™ BBs are designed and manufactured with durability, serviceability, and quietness in mind. They create a precise and functional interface between the BB shell of the frame and the cranks, ensuring smooth rotation without interference with the cranks.

Each ThreadFit™ BB is available in a series of BB fit kits for use with a wide variety of road bike and MTB cranks.
