Factory-Correct Shiv TT Headset Service
Headset bearings can develop roughness, play, or contamination over time, particularly on bikes exposed to sweat, moisture, and repeated cockpit service. Replacing worn bearings with the correct factory components helps restore precise steering and proper headset adjustment.
Genuine Specialized S202500004 provides the correct upper bearing, lower bearing, and split compression ring for compatible Shiv TT Disc applications without requiring replacement of the complete cockpit hardware.
