** FIT KIT REQUIRED FOR USE **
ThreadFit 30 comes with a Center Sleeve for 73mm BB shell. For 68mm shell - sleeve is required(included in Fit Kit #2 for DUB Road cranks).
ThreadFit 30 bottom bracket is silky smooth and long-lasting thanks to legendary, angular-contact bearings. They actually get faster over time as their contact surfaces wear, because they are build 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.
