Thanks to the addition of an updated red anodized Large Split Ring and a Large Diameter Bushing, the Chris king Hub Tool is now compatible with all King hubs except the R45 series. Updated tools will feature the red anodized parts instead of the previous pewter Split Ring in order to differentiate the parts. Specifically, the new additions allow users to remove and service the bearings in the Large Diameter Chris King ISO front hubs. For those who already own a tool, Red LG Split Rings and LD guide bushings will be available separately and are compatible with all existing hub service tools. An updated service manual can be found in their tech section, as well as a 9 page instructional on how to brew their coffee. You’re welcome.
