What brand and model hub does it fit?

I ordered this by mistake, it fits the newest Hunt 50 aero wheels and whichever hubs they use. I believe they use Novatec but as far as I know the design is cross-compatible as long as the ratchet system is the same.

There is very little cross-compatability in hubs. I wouldn't be surprised if your freehub body only fit one particular model hub.
