Zipp Cognition Hub Bearings

No, these are specifically engineered for Zipp Cognition Disc Brake NSW hubs. They are not universal, so please verify your hub model before purchasing to ensure a proper fit.

Each pack contains two bearings. Depending on your specific hub model and whether you are servicing the front or rear, you may need multiple packs to complete a full overhaul.

If you have a dedicated bearing press and the appropriate drifts, you can perform this service yourself. However, because these are precision components, we recommend having them installed by a professional mechanic to avoid damaging the hub shell or the new bearings.

You should consider replacing your bearings if you feel grinding or roughness when spinning the axle by hand, or if you notice lateral play in the wheel while it is mounted on the bike. These symptoms typically indicate that the internal seals have failed or the races have worn down.

Yes, these are high-quality sealed cartridge bearings. The seals are designed to keep contaminants out and lubricant in, which is essential for maintaining performance in the varied conditions disc brake wheels often encounter.
