FAQs

Does this kit work with the original Hope Pro2 hub?

No, this kit is specifically designed for the Pro2 Evo and Pro4 models.

Do I need special tools to install this?

No, it is a press-fit design that can be installed by hand, though a rubber mallet may be used if the fit is particularly tight.

Will this change my chainline?

The kit is designed to maintain the standard chainline for the specified hub model when properly installed.

Does the kit come with a 12mm axle?

No, this kit includes the hub end caps only; the 12mm thru-axle is typically provided by your frame manufacturer.

Is it necessary to use grease during installation?

Yes, a light application of waterproof grease on the interface points helps prevent seizing and protects against moisture ingress.

Troubleshooting

End caps feel loose after installation

Verify you are using the correct kit for your specific Pro2 Evo or Pro4 hub; ensure the end cap is fully seated.

Wheel does not fit into the frame dropouts

Check that your frame is indeed designed for the 142x12mm standard and that the axle is fully inserted through the hub.

Pros and Cons

Pros

  • Retains your high-quality hub investment for use on new frames
  • High-grade CNC construction ensures long-term durability
  • Installation requires no specialized hydraulic tools
  • Lightweight design does not add significant rotating mass

Cons

  • Not compatible with Pro2 (non-Evo) hubs
  • Requires proper alignment during press-fit to avoid damage
  • Conversion may require re-dishing the wheel in specific rare frame scenarios

Setup, Compatibility & Care

To install, remove the existing end caps from your Pro2 Evo or Pro4 hub—this can usually be done by hand or with simple pliers wrapped in a cloth to prevent marring. Once removed, ensure the internal axle is clean and lightly greased. Press the new 142x12mm end caps into position until they seat firmly against the hub shell. Always double-check that the axle spins freely before installing the wheel into the frame. For care, inspect the O-rings on the end caps during annual service and re-apply a thin layer of waterproof bicycle grease to ensure a weather-tight seal.
