I had a junior team coach visit me in my tent and while he was checking out my bike he laughed and said "a lock ring, no one uses lock rings anymore." I replied that I did and that's it's weight was insignificant when compared to it's potential value. A couple of weeks later, one of his juniors needed to remove a stuck cog. After a lot of frustration and two broken chain whips I visited their tent with my EAI tool. I tried with all of my strength to remove the cog, but it wouldn't budge. I was pretty much at the point of giving up when I noticed the 8mm hex opening at the end of the tool and realized that's for the cheater bar. I inserted an 8mm hex wrench and then there was sufficient torque to pop the cog right off. At the point that same coach asked where I got the tool and how much it cost. I answered his question and then I offered up that it also removed lockrings. He smiled and said "got it."
