Zipp Spring and Pawl Set

You likely need a replacement if you notice inconsistent engagement, a slipping sensation when you pedal hard, or if the hub has become noticeably louder or quieter than usual. If you are performing routine maintenance and the pawls show visible rounding or the springs have lost their tension, it is time to swap them out.

No, this specific kit is designed exclusively for Zipp ZR1 hubs. Before purchasing, verify that your wheelset is equipped with the ZR1 hub system, as older Zipp hubs use different internal components.

If you are comfortable with basic drivetrain maintenance and have the necessary tools to remove the freehub body, you can perform this installation yourself. However, if you are unsure about hub disassembly or reassembly, a professional mechanic is recommended to ensure the pawls are seated correctly and the hub is properly lubricated.

This kit includes the replacement springs and pawls required to restore engagement. You will still need to provide your own hub grease, as it is not included in the package, and you should ensure you have the appropriate tools to access the hub internals.

There is no set mileage interval, as it depends heavily on your riding conditions, weather, and power output. It is best to inspect these components during your seasonal wheelset service or whenever you perform a bearing overhaul.
