This Specialized headset bearing is an individual Campagnolo-style cartridge bearing with custom dimensions for Specialized Future Shock headsets. It serves as a direct replacement for a worn or rough bearing on Roubaix, Ruby and Diverge models from the 2017 and 2018 model years, restoring smooth, precise steering without replacing the entire headset assembly.
The sealed steel cartridge uses a 45 by 45 degree contact angle on both faces to match the bearing seats of the Future Shock headset. Black rubber seals help keep water and grit out of the bearing, and each unit is sold individually, so a single worn bearing can be swapped during routine headset service.
