You might need a different lockring
- Familiarity: I've put it through the wringer
- Fit: True to size
On my DT Swiss 350 hubs, the external lockring (that came with the wheels) wouldn't get tight enough to lock on the disk. This wasn't a problem before with the 6-bolt disks and centerlock adapter that came with the wheels.
I had to use an internal wrench lockring (that usually come with MTB discs) instead and it worked great. So just keep in mind you might need that lockring with certain hubs.
