The Microshift Advent 1×9 groupset is a really nice and affordable 1X option. I just purchased a Giant Talon 2 mountain bike that came with this group. I wanted to try out a 1X since it’s one of the things all the modern mountain bikes have. So far, I’m really happy with it. I use my Talon strictly for trails and have not missed a front derailer at all. The 11x42t cassette provides a great range and shifts beautifully. I’ve had no chain drops or any issues really.
I have the Advent 1×9 rear derailleur with clutch, trail trigger shifter, and the 11x42t 9 speed cassette. Everything looks like real nice quality. I’ve never had a clutch derailleur before, but it seems neat, and you can turn it on and off. Check it out:

I decided not to clean things up before taking the pictures because well, it’s a mountain bike. And the group works great even with some dirt. Microshift has lots of great info out there for the group including a very helpful installation video.
I like the shifter, but it is taking some getting used to. Instead of having a push and a pull trigger, it’s push for both. Works great but does take a bit of getting used to.
You get all this and at a really nice price. A really good option to convert a bike to a 1X. Get yours today on Amazon:

Thanks
But… 9 gears isn’t many to span an 11-42 range. In my own area I could really use a bigger range because of the hard climbs but for my winter bike, when I won’t climb the hardest ones, this could be good. I’ll check out the price before I buy new parts for the 3X10 that is worn out.

Thanks for your thoughts. Haven’t done a lot of big climbs yet, but the gearing seems good for it to me. I’ll keep testing it out.
