FAQs

Will this work on Zipp Cognition hubs?

No, this set is exclusively designed for the Zipp ZR1 hub platform and is not compatible with Cognition or older Zipp hub designs.

How often should I replace these parts?

There is no fixed mileage, but you should inspect the pawls and springs if you notice delayed engagement, skipping, or if the hub has been exposed to extreme weather conditions.

Do I need special tools to install this?

Generally, standard shop tools like a pick, a flathead screwdriver, and appropriate wrenches for your thru-axle setup are sufficient for standard maintenance.

Can I use standard bearing grease on the pawls?

No. Use only the grease or oil specified by Zipp, as standard heavy bearing grease can prevent the pawls from springing out quickly, leading to engagement failure.

What is the purpose of the wire snap ring?

The wire snap ring helps retain the pawls and springs within the freehub assembly, ensuring they remain in the correct position when the freehub is removed from the hub shell.

Troubleshooting

Freehub feels sluggish after maintenance

You likely used too much grease. Remove the freehub body, wipe off excess grease, and use a thinner, manufacturer-recommended hub oil.

Pawls are not clicking

Check that the coil springs were installed in the correct orientation and that the pawls are sitting flush in their channels.

Setup, Compatibility & Care

This kit is strictly compatible with the Zipp ZR1 rear hub. Before installation, ensure the hub shell is clean and free of old, sticky grease or debris.

Carefully remove the freehub body from the axle.
Remove the old, worn pawls and springs from their seats.
Clean the pawl pockets with a mild degreaser and dry thoroughly.
Install the new springs and pawls, ensuring they are seated correctly before sliding the freehub body back into position.
Apply a light layer of Zipp-approved hub lubricant to the pawl faces. Avoid over-lubricating, as thick grease can cause the pawls to stick and fail to engage properly.
