Zipp Cognition Rear Hub Seal Cap & V-Ring

You should inspect these parts if you notice grit or resistance when spinning your rear wheel, or if you see visible wear, cracking, or deformation on the rubber seal. Replacing them during routine hub service is a proactive way to prevent contaminants from damaging your internal bearings.

No, this specific kit is designed exclusively for Zipp Cognition rear hubs. It will not fit older Zipp hub models or other brands, so please verify your hub model before purchasing.

Generally, you can install these by hand or with a light press, but you will need standard hub service tools to remove the cassette and access the hub internals first. Always ensure the area is clean and lightly greased before seating the new seal to ensure a proper fit.

It is strongly recommended to replace both the seal cap and the V-ring together as a set. Even if the old V-ring appears intact, the rubber material often loses its elasticity over time, which compromises the seal's ability to keep moisture and debris out of your hub.

This kit specifically covers the driveside seal cap and V-ring assembly. It does not include hub bearings, grease, or other internal components, which would need to be purchased or serviced separately.
