Hope Pro 4 Axle Conversion Kit

Yes, this conversion kit is compatible with both the Pro 2 Evo and the Pro 4 rear hubs, provided they are the 135/142mm versions.

It adapts your hub to fit a 12x148mm Boost frame, but keep in mind that this is a mechanical conversion. While it fits the frame, it does not change the actual flange spacing of the hub, so you may need to re-dish your wheel to ensure it is perfectly centered.

The kit includes the specific end caps and the necessary axle required to convert your existing 135/142mm hub to the 12x148mm Boost standard.

Generally, no. Hope hubs are designed to be serviced without proprietary tools. You can typically remove the existing end caps by hand or with a simple set of pliers, and the new ones should press on easily.

This kit is a cost-effective way to keep your current, reliable Hope hub when upgrading to a new frame. It saves you the expense of a full wheel build while maintaining the performance you are already used to.
