Chris King ThreadFit 30 BSA Bottom Bracket

Chris King ThreadFit 30 - to fit 30 mm and DUB spindle cranks in BSA bottom bracket shells.

ThreadFit 30 bottom bracket is silky smooth and long-lasting thanks to a 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 of the 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.

Why CK made this:

The humble threaded bottom bracket is often the first part installed on a new frame, and the last one the rider thinks about during the life of the bike, but the bottom bracket has a direct effect on pedaling efficiency. This is where you put your power into the bike. Having the absolute best interface between your effort and your bike's forward momentum makes your ride better. The ThreadFit 30 is how CK make bikes that take 30 mm cranks the best they can be.

Why you want it:

You want this bottom bracket because it offers super low drag. 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!
