Need a different driver body for your WTB hub? Maybe looking to replace your hub bearings after many wet months of winter riding? Either way, you've come to the right place. All internal wear items on our WTB hubs are available here for easy ordering on WTB.com.

Frequency/Proterra and Frequency Comp/Speedterra internal parts are interchangeable. These replacement parts are a direct replacement for those that come in Frequency hubs, while many of them will be plug-and-play upgrades for Frequency Comp hubs.

All internal parts of our Serra hubs are specific to the Serra family of hubs. Do not attempt to upgrade them with Proterra/Speedterra parts.

*Please note that hubs previously referred to as Proterra are now Frequency while hubs that were previously referred to as Speedterra are now named Frequency Comp.
