Chris King Bottom Bracket ThreadFit 30

Why we are building it
We build bearings, so we build bottom brackets. The unassuming, threaded bottom bracket is often the first part you install in a new frame—and the last you think about for the entire life of your bike. Yet it has a direct impact on your pedaling efficiency (read: speed). This is where you transfer your power to the bike. The best possible interface between your effort and your bike's propulsion makes every ride better. ThreadFit™ 30 is our way of making bikes with 30mm cranks as fast and efficient as possible.
Why you want it
ThreadFit™ 30 fits 30mm and DUB axle cranks in BSA bottom bracket shells.
Our ThreadFit™ 30 bottom bracket runs silky smooth and lasts forever – thanks to our legendary angular contact ball bearings, in steel or ceramic, among the best in the business. They even get faster over time as the contact surfaces wear in, because we manufacture them to ultra-tight aerospace tolerances and use precision-machined Delrin spindle bushings to achieve a perfect, exact fit between the crank and frame.
Our ThreadFit™ 30 bottom brackets are available in a full range of elegantly anodized colours, and each comes with a Fit Kit that allows it to be used with a wide range of road and MTB cranks.
ThreadFit™ 30 comes with a center sleeve for 73 mm bottom bracket shells. For 68 mm shells, the PBB082 sleeve is required (included in Fit Kit #2 for DUB road cranks).
