It's the stock NX Eagle drivetrain including a 12-speed chain. It's a stock Shimano 10-speed cassette with two cogs removed out of the high end (bigger jumps in the gears I use less). It's so good I suspect I could shift all 10x without setup issues, but I prefer to run 8x in order to get a really nice chainline in my grinding gears.
I mostly gave up trying to math my way through inter-compatibility. I do 95% of my experiments by trial and error. If you like different-drivetrains and haven't seen it, check out my [**Titan review**](https://nsmb.com/articles/banshee-titan-review-part-two/) or [**SB104**](https://nsmb.com/articles/my-yeti-sb104-sheared-pedal-pins-terrified-grins/) piece. On those bikes I was using a 9-speed XTR shifter, Wolf Tooth Tanpan, 11-speed Zee Derailleur, and 8-speed cassette setup 1x8. The Titan piece also has links to my 2x7 and 2x8 experiment. I'm working on another edition to my series 'Does The Future Have Fewer Gears' as well. I love playing with this stuff.
