Zipp Magnet for Cognition NSW Clutch

This magnet set is designed exclusively for Zipp Cognition NSW rear hubs. It will not fit other Zipp hub models or third-party hub systems.

You should consider replacing the magnets if you notice inconsistent power transfer, delayed engagement when you start pedaling, or if the hub has become noticeably noisier than when it was new. These symptoms often indicate that the internal clutch mechanism is no longer engaging as crisply as it should.

Yes, this kit includes both the inner and outer magnets required to service the clutch engagement mechanism. It provides the essential components to restore the hub to its original factory performance specifications.

Replacing these magnets requires basic mechanical knowledge and specific tools for hub disassembly. If you are comfortable performing routine hub maintenance, you should be able to handle this, but we recommend consulting the official Zipp service manual or visiting a professional mechanic if you are unsure about the procedure.

While the primary purpose of this kit is to restore engagement performance, a properly functioning clutch mechanism is inherently quieter and more efficient. If your current magnets are worn or damaged, installing this fresh set should help eliminate the erratic noises caused by poor engagement.
