Chris King ThreadFit 24 BSA Bottom Bracket

Chris King ThreadFit 24 - to fit 24 mm in BSA bottom bracket shells.

ThreadFit 24 bottom bracket is designed and built to be durable, serviceable, and silent. Manufactured to create the most precise interface between your frame's bottom bracket shell and your cranks, it makes your cranks spin lightly and easily, without interference, for the lifetime of your bike (with a little regular service). King's legendary, angular-contact bearings, both steel and ceramic, are the best in the industry, and actually get faster over time, as their contact surfaces wear.

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 24 is how CK make bikes that take 24 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!
