Threaded Bottom Brackets


We've been making our own stainless-steel sealed bearings here at King for 35 years and never has there been a component that benefited more from their quality and durability 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. We make our own bearings in-house and our process allows us to place more balls per bearing, 24 to be exact, than our competitors. More rolling elements per bearing translates to a stronger overall bearing system. A bottom-bracket specific upgrade to our legendary sealing system allows the bearings to be purged and re-greased using our precision made injector tool. This combination of strength and serviceability gives us the confidence to offer an industry-leading 5-year warranty on our bottom brackets.

The Chris King BB Injector Tool is designed specifically for use with Chris King Bottom Brackets only. This all-aluminum tool is designed to be used in conjunction with many popular push-type grease gun systems by threading directly onto the gun nozzle. We also provide a zerk fitting allowing for use with a universal fitting grease gun.
