Race Face Vault Freehub Body

No, this specific freehub body is designed exclusively for the Race Face Vault rear hub. It will not fit other Race Face hub models like the Trace or older proprietary designs.

Yes, this Micro Spline freehub body is the necessary component to convert your existing Vault hub to run a Shimano 12-speed MTB drivetrain, which requires the Micro Spline interface.

Like all aluminum freehub bodies, it is susceptible to cassette cog bite if the lockring is not tightened to the manufacturer's torque specifications. We recommend applying a light layer of high-quality freehub grease during installation to ensure smooth engagement and prevent seizing.

The Vault hub system is designed for tool-free end cap removal, but you may need a cassette lockring tool to remove your current cassette. The freehub body itself typically slides off once the end caps are removed, though having a set of cone wrenches or a vise can be helpful depending on your specific hub configuration.

Aluminum is used to keep the overall weight of the hub assembly as low as possible, which reduces rotational mass. While steel is more resistant to cassette cog bite, the high-grade aluminum used here balances durability with the performance needs of modern mountain biking.
