- 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
- 12mm insertion depth and 3mm lead-in for easy installation
- Both the TR and TR1 use the same 1-1/8 high-complement caged ball bearings
- The cone and crown race are the same part creating mirror top and bottom cup assemblies
