The Zipp Sub-9 and Super-9 disc wheels deserve the best possible bearings, and the CeramicSpeed upgrade kit delivers exactly that. This kit includes one 61803 and one 61903 bearing — the correct combination for Sub-9 and Super-9 hub shells — along with a grease syringe for correct installation.

  • Combined 61803 + 61903 ceramic bearing set for Sub-9 and Super-9 hub shells
  • CeramicSpeed ceramics for measurably lower rolling resistance than steel
  • Ceramic construction resists corrosion and wear for extended service intervals
  • Grease syringe included to ensure correct lubrication from installation
  • Genuine Zipp-approved CeramicSpeed specification

Replacing standard bearings with CeramicSpeed ceramics is one of the most effective performance upgrades for aerodynamic disc wheels. Tighter manufacturing tolerances mean smoother rotation, less friction heat and longer time between services. The two-bearing kit covers all bearing positions in the Sub-9 and Super-9 hub shells.

Fits: Zipp Sub-9 and Super-9 hub shells. Professional installation recommended.
