I've been waiting to make this post because I wanted to put some miles on my 30T Mighty-Mini first, and I'm thrilled to report that all the chainline issues that I was worried about are all wiped away. Look at that crazy chainline! I'm running a KMC 10.93 chain to a 10-speed Shimano XT 11-36T cassette with a 42T Wolftooth expander cog.
I am now a firm believer in narrow-wide chainrings. They are amazing at guiding a chain onto the teeth even at crazy angles! And look at how many spacers I used to push the BBSHD out! My bottom bracket is 68mm.
Those spacers were necessary for the 42T Luna Eclipse to clear the chainstay. So does it work? Yes! At first, it made a little noise in the first two larger cogs and skipped a little under load, but after a few miles, it's all quiet and smooth now. Now here's the bad part. Look at all those aluminum shavings from the chainring! I wish a steel version was available. It would last a lot longer and be a lot stronger. I've seen people break teeth on these things. Please Luna, make a steel version someday =)
For now, this will do. I'm thrilled that I can use this chainring because I wanted a 1x setup. I've purchased a 50T OneUp Shark extender cog that I will install very soon (I'm going to an 11-speed setup).
