Zipp Cognition Disc NSW Rear Axle

No, this specific axle is engineered exclusively for the Zipp Cognition Disc NSW rear hub. It will not fit standard Zipp hubs or other wheelset models.

While the installation is straightforward, you will need standard bicycle maintenance tools, such as hex keys and potentially a torque wrench, to ensure the axle is seated correctly. We recommend consulting the Zipp service manual for your specific wheelset to follow the correct torque specifications.

This product is the axle shaft itself. It does not include end caps, bearings, or other internal hub components, so you will need to reuse your existing hardware or purchase those parts separately if they are damaged.

You generally only need to replace the axle if the original has become bent, the threads have stripped, or it has sustained damage from a crash or improper maintenance. If you are experiencing play in your rear wheel that cannot be resolved by adjusting the hub preload, inspecting the axle for wear is a good next step.
