Bottom Brackets

Chris King ThreadFit 24
Chris King has been making stainless-steel sealed bearings for 34 years, and never has there been a component that benefited more from their quality than the external bottom bracket. The Chris King bottom bracket is specifically designed for crank systems with outboard bearing cups and is available in the full assortment of colors that only King can do. It all starts with the bearings. King makes their own bearings in-house and the process allows them to place more balls per bearing—24 to be exact . More rolling elements per bearing creates a stronger overall bearing system. This bottom bracket works seamlessly with King's precision injector tool (sold separately) so that flushing new grease into your bottom bracket is a quick and easy operation.
