Chris King Anodized Headset Spacer 1-1/8" Kit Pewter

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 and duty, there is no more room for compromise here than in our other components.
Our precision headset spacers are made to the same exacting standards as our 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. Fashionable? Yes. Precision? Questionable. In addition to sizing variances, carbon fiber has poor qualities in compression, which is what it is subject to during adjustment and from trail forces as the bicycle is ridden. We believe that this is an impractical material to specify spacers to be made from when our 3mm spacer weighs just 2.5 grams by the way.
