It alleviates the use of a chain whip when changing cogs. Rather than screwing on the cogs each time, you screw that base on once, and then the cogs fit onto those spline like notches, and then a lockring is threaded on top. Makes it easier to change cogs, and is a cheaper overall system.
I have no clue how to get it off, assuming there isn't a special tool, I would think you place a miche cog on it, and the use a chainwhip. Again, no ****ing clue, just a guess.
If you don't need it, take it off with a big pair of channel locks. This might actually be a good time to switch if you wanted to.
The system is growing on me.
