My Ibis MX came with a 1x Praxis Zayante. I emailed Praxis on what was required to make it 2x. They replied the same day! They have great customer service.
2x chain ring came within a few days. Looks great, shifts great. I have not had it long enough to comment on long term durability. The only downside if you plan to chain your gearing often the direct mount chain rings cost a lot more than the 4/5 bolt chain rings. I paid $170 for 2x LEVATIME II X-KIT chainring vs $20 to $80 4/5 bolt chainrings
