Finally test-rode my 1x setup. Microshift XLE 10 clutch real derailler and bar-end shifter. Crank is Bontrager 7050 "race" (whatever that means) formally a triple.
Shifting is absolutely flawless. Has all the gears I need however I haven't tried it on any hills yet. Rode it on gravel and chain hasn't come off yet so that's a good sign!
Maybe this weekend I will take it to some real off-road trails and see how it performs.
