So ive got a set of paul hubs. They come with a stepped lockring for use with cheap narrow cogs that dont extend past the cog threading on the hub.
Ive got a dura ace cog. It extends past the cog threading about half a mm.
The lockring was installed with the stepped side in even though it was not needed. No problem until the cog comes unthreaded yesterday while i was skipping.
Because the lockring was stepped, it was only threaded onto the two outside threads on the hub. The two that it was threaded onto were totally sheared off. I fixed it by flipping the lockring around so the flat side was up against the cog. It is now engaging the threads that were previously untouched. Im hoping this will hold but i may look into getting a replacement from paul since it is still within the warranty period.
Has anybody had a problem like this? If you are setting up a paul hub or any other with a stepped lockring, make sure you need the step before you use it.
