Chris King ThreadFit 30 Bottom Bracket fits 30mm spindle cranks in 68mm BB shells and SRAM DUB cranks.
ThreadFit 30 bottom brackets are silky smooth and long-lasting thanks to Chris King's 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 they are built 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.
