Replacement Hub Parts

Need a different driver body for your Proterra, Speedterra or Serra hubs? 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.

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