I went from XT 1x to Zayante Carbons.
Praxis was around the same price as XTR and I wanted a Q closer to road.
I also think they were the second lightest cranks I looked at (XTR, Dura Ace). I think Force1 was a bit lighter. Not a SRAM guy.
From what I read, Praxis had an excellent reputation for shifting. This was a factor in case I was going back to a 2x.
I also liked the 'modular' thing with the spider and rings, and the availability of third party rings.
Installation was easy; BSA, just follow the instructions and watch the size of the dust covers.
Cranks and BB come with everything, including some crank arm protectors (which I just found in the box!).
I got maybe 50 miles on them and so far no issues.
In the end I went with a 34t Blackspire DM ring.
Probably going to change my road bike over to Zayante carbons too.
Hope this helped.
