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. Lacking exactness, there will be little you can do to achieve and maintain proper adjustment. While spacers are simple in their design their function is essential.
Each spacer is lathe-cut from high-grade aluminium bar stock in a single operation ensuring exactness of size, concentricity, and parallel surfaces.
