Zipp Spring and Pawl Set ZM2

If you notice slipping under load, inconsistent engagement when you start pedaling, or excessive noise while coasting, your pawls and springs are likely worn. This kit is the standard fix to restore that crisp, immediate engagement Zipp hubs are known for.

No, this set is exclusively designed for Zipp ZM2 hubs. It will not fit older Zipp hub models or the newer Cognition hubs, so please verify your hub model before purchasing.

If you are comfortable with basic drivetrain maintenance and have the necessary tools to access the freehub body, this is a straightforward replacement. However, if you aren't familiar with hub internals, a professional mechanic can install these quickly to ensure everything is seated correctly.

Yes, always use a high-quality, lightweight hub grease or the specific lubricant recommended by Zipp for the ZM2 system. Avoid heavy, sticky greases, as they can cause the pawls to stick and fail to engage properly.

This kit includes the essential pawls and springs required to refresh the engagement mechanism. It does not include bearings, seals, or the freehub body itself, so inspect those components while you have the hub apart to see if they also require replacement.
