This is the Chris King Headset Spacer Kit for 1-1/8 inch steerer tubes, machined to the same tolerance standard as King’s headsets so each spacer’s faces sit perfectly parallel under the stem.
It tunes bar height during a new build or a fit session without introducing the wobble cheap stamped spacers can add — the kit covers stack experiments on both straight and tapered-steerer forks.
Chris King Precision Components has machined bicycle components in Portland, Oregon since 1976, making its own bearings from domestic-mill materials and anodizing parts in-house.
