Lockring to hold your 13t cog in place.
When to use AB lockring?
For when you want to remove the 11t cog from your cassette. This is ideally used when you’re looking to put together an expanded range 1×10 system from your current setup. You can do this dropping the 11T cog off the bottom of the cassette and adding more range to the top.
