Chris King started making components in 1976 and have been refining them ever since. The Chris King components are built to be precise and dependable and sets the standard for quality function delivering precision performance that is built on the same pedigree of Chris King headsets from the past 40 years.
At Chris King, we design and make our own bearings in-house. They are the foundation of everything we sell, and producing them ourselves gives us full control over the entire process to manufacture bearings that are purpose-built for use in our components. This allows us to design products that not only perform better but also have greater longevity. Every single Chris King bearing is inspected and assembled by hand.
Unlike common radial bearings, we build sealed angular-contact bearings that allow for adjustment as they are used. Rather than wear out, our bearings wear in; like a fine wine or a quality guitar, they get better with age. All of our bearings are user-serviceable without special tools. Simply remove the snap ring and seal, clean, and re-grease the bearing for a lifetime of faithful rolling.
