I'm looking to create a clone of an Ibis DV9 for my 5'1 12-year-old. 

Here's the DV9 geo chart:



My only other requirement is boost, so it's compatible with an existing wheelset I'd like to use. 

So far, the closest option I've come to is the Trifox: https://trifoxbike.com/products/sdy20-carbon-mountain-bike-frameset-hardtail-boost?variant=32794338361423

But - at close to $660, it's about 2x the price of other Chinese Hardtail carbon frames, and I don't love the logo/color. 

What other options should I be looking at?
