InSet™ is the latest addition to the Chris King® NoThreadSet™ family. InSet™ is a low-stack threadless headset designed for use with contemporary frames featuring what would traditionally be called "oversized" headtubes.


  • As times have changed, so have the specifications of many of the greatest bicycle designs.
  • These new large headtubes allow frame manufacturer’s greater surface area on which to attach top tubes and downtubes with the overall result being improved frame strength and rigidity. We pride ourselves on adapting Chris' forward-thinking original modular designs into ever-evolving configurations to meet most new bicycle designs.
  • The Chris King® InSet™ now brings King's legendary bearing quality and time-tested durability to even more bicycle models.
