A-Headset ZS Internal Headset
Works with Aluminum Frames that take an internal (not-integrated) headset only.
The Zero Stack features cups and cones that work together with a simple O-ring to seal out contaminants and increase the headset's life expectancy.
· The compression ring is integrated into the top cover creating one simple, light part
· LubeAlarm seals audibly alert the rider when more grease is needed in the headset, extending headset life
· Features 1-1/8" high-complement caged ball bearings
· The cone and crown race are the same part creating mirror top and bottom cup assemblies
