If you are building a touring bike straight pull 28h 2x just doesn't seem like it will be a very reliable wheel for that bike. Plus putting that kind of money towards a Roam is probably a little over the top. Also that particular hub probably won't work not that bike, it looks like those are quick release wheels and non-compatible with thru-axles.
For a touring bike I want generally at least 32h using J-Bend spokes for simple fact if you do break a spoke, most shops will have J-bend spokes. Also make sure everything works on the bike size wise.
