Chris King® THREADFIT™ 30 Bottom Bracket (ceramic)

ThreadFit™ 30 fits 30mm and DUB spindle cranks in BSA bottom bracket shells. Our ThreadFit™ 30 bottom bracket is silky smooth and long-lasting thanks to our legendary, angular-contact bearings, both steel and ceramic, the best in the industry. They actually get faster over time as their contact surfaces wear, because we build them to ultra-tight aerospace tolerances, using machined, Delrin-spindle sleeves to create a perfect and precise fit between cranks and frame. That’s where the low-drag and butter-smooth feel come from. You want this bottom bracket because it offers super low drag. You want this bottom bracket because it can be opened, cleaned, and repacked for years of faithful service. You want this bottom bracket because you don’t want to think an awful lot about your bottom bracket. Our ThreadFit™ 30 bottom brackets come in an array of beautifully anodized colors, and each one includes a Fit Kit that allows it to be used with a wide selection of road and mountain bike cranks.
