Chris King ThreadFit™ 30 bottom brackets are silky smooth and long-lasting thanks to their 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 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.
