Zipp CeramicSpeed Bearing Kit

This kit is specifically engineered for Zipp Super-9, 900 tubular, and Sub-9 disc rear hubs. It is not a universal kit, so please verify your specific hub model before purchasing.

The main advantage is a reduction in rolling resistance. By replacing standard steel bearings with these precision ceramic options, you decrease internal friction, which can lead to measurable wattage savings during a ride.

Yes, the kit comes with the required 61803 and 61903 bearings, as well as a grease syringe. You will still need the appropriate bearing press tools to complete the installation properly.

If you have experience with hub maintenance and own the correct bearing press tools, you can perform this service yourself. However, because these are precision components, we recommend having a professional mechanic install them to ensure they are seated perfectly and operate smoothly.

Ceramic bearings generally require the same maintenance schedule as standard bearings. We recommend checking them periodically for play or roughness, especially after riding in wet or gritty conditions, and re-greasing them as part of your regular drivetrain maintenance.
