FAQs

Can I use this with a Shimano 11-speed cassette?

No, this freehub body is specifically designed for the Shimano Micro Spline 12-speed standard.

Do I need new bearings to install this?

The freehub body comes with its own internal components, but it is good practice to inspect your hub shell bearings while the assembly is removed.

What is the purpose of the included adaptor?

The adaptor is required to ensure the freehub body is correctly spaced and supported by the axle and hub shell architecture.

Is this compatible with the Hope Pro 4 hub?

No, the Pro 2 Evo and Pro 4 hubs have different internal specifications; this part is exclusive to the Pro 2 Evo.

How often should I service the freehub?

Service intervals depend on riding conditions, but cleaning and lubricating every 6 months is recommended for average use.

Troubleshooting

Cassette has play or wobbles

Check that the cassette lockring is tightened to the recommended torque and ensure the drive side axle adaptor is fully seated.

Freehub feels sluggish or sticks

Remove the freehub body, clean the old lubricant off the pawls and springs, and apply a fresh, light hub oil.

Freehub body does not fit onto the hub

Verify that your hub is a genuine Pro 2 Evo model. If the hub is a different series, such as Pro 5, this component will not fit.

Setup, Compatibility & Care

To install this freehub body, you must remove the existing end cap and freehub assembly from your Pro 2 Evo hub. Ensure the hub seals are clean and lightly greased before sliding the new Microspline body onto the axle, using the provided drive side adaptor to seat it correctly. It is essential to verify that your hub is an authentic Pro 2 Evo model, as other generations may have different axle or seal specifications. Regular maintenance involves cleaning the pawls and ratchets inside the hub shell and applying a light, high-quality hub oil or grease to keep the engagement mechanism moving freely. Avoid using thick greases that could cause the pawls to stick.
