Front and rear axles can change to anything apart from 150mm rear IIRC so you’d be fine there. I really rate their hubs, easy to convert and rebuild and seem builtproof. I spec them on all my bikes unless I can afford something a bit lighter and less reliable. Those wheels would be a good investment
Although you;d hear a lot of rubbish about Superstar components I had a set of Am wheels from them in sale for £110 and I was really suprised at the build quality and finish, I’d have a look. Other options if you want to spend a little more are Crossrides and easton haven but I dont believe the havens are interchangeable.
For the type of riding your doing i’d say hope hoops with Stans Crest rims, or Arch Ex rims if you think you’ll be doing a bit more aggressive riding.
