Spacers are an important link in properly setting up your headset. While used to adjust the height of your stem, they transfer important alignment from the bottom of your stem to the top of the headset. While spacers are simple in their design and duty, there is no more room for compromise here than in King's other components.
Their precision headset spacers are made to the same exacting standards as their headsets. Each spacer is lathe-cut from high-grade aluminum bar stock in a single operation ensuring exactness of size, concentricity, and parallel surfaces. Many of the other headset spacers available in the market are saw-cut from a tube resulting in variances of these all-important tolerances. This is especially true with the now popular carbon fiber headset spacer.
