Information

---

We’re going to assume that you’ve landed on this page because you want to either swap your freehub body for a different style or simply replace it with the same one, so it’s important that you read all the information below to help ensure you choose the proper freehub body for your hub. You can also refer to the “Freehub Body Identification Guide” in the link at the bottom to see more pictures and details on each freehub body.  Here in the shop we often refer to “freehub bodies” as “drivers”, so if you read or hear that term from us, that’s what we mean.  

After you select a given driver,  you will see a list of compatible hubs.  If you don’t see your hub model listed for that driver, it means that driver will not fit that hub.  If you have an H3 or Mi5 hub, refer to the notes below to help navigate your way to the correct driver.  Most hub models are engraved on the center section of the shell.  H3, Mi5 and Mi6 hubs are engraved in very small letters and numbers above the “W” logo.  Look carefully.  If you have one of our really old hubs with an aluminum, steel, or 7/8 speed titanium driver, none of the available drivers will fit nor do we have replacements available.  Sorry!
