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.
