Race Face Vault Hubs Teardown - June 14, 2018, 10:54 a.m.

To be clear, I don't think anything has changed. The ratchet-rings still drop in, but the hub side ratchet ring slides into a steel drive ring that threads into the hub body. Under load, this drive ring tightens into the hub body. Add in a bearing's lifetime of riding, moisture, use etc, and inevitably the drive ring is seized into the hub. It needs to be removed when changing the bearings since the ID of the ring is smaller than the OD of the hub bearing. It's an awful design, and single-handedly why DT hubs are massively over-rated in my opinion.

I'd add to the comments below that the thread-in DT drive ring that has to be removed to change out the drive-side hub bearing is simply a terrible design. When other hub manufacturers can make a hub that can be fully rebuilt without specialist tools for reasonable money, there's no way I'm paying out the money DT ask for for a hub that needs a blow torch & a (actually several depending on how many you break getting the seized drive ring out) specialist tool to replace the bearings in.

Third guy has to go home, but has just enough time to drive you to the top for one more lap.
