Interesting. I just bought a 2019 Epic frame, haven't built it up yet. May pick this up just in case I don't like the Brain come riding season. For comparison sake, here's the Cames ad on eBay (
https://www.ebay.com/itm/326076108030) and here's the BikeYoke ad (
https://bikeyoke.com/en/yoke-ep02/ep02?srsltid=AfmBOopr-gZHGfZ2XgN7btRhGpBLBHGgyvocbaERHyTMxtfXBWi9UV_q). I'm mostly curious on the difference between the Cames/AliX versus BikeYoke. One uses 200x51-57mm and the other uses 190x40-51mm. Assuming they both have similar tire clearance or seat stay bridge clearance at bottom out, the Cames/AliX would have a higher ride height and more travel.
Edit: Taking a second look at the AliX ad, I don't think they mention shock size, above response only assumes Cames and AliX are the same based on them having the same general design.
