Its Possible, but expect to pay more money than you will ever want to. Unless you know someone in a machine shop.
If you’re really going to go after it, 6061-T6 or even 7075 if you can get it are the most common as far as chainrings, etc goes. Other things that are cast might be a slight variation, but you can get plates from almost any major metal supply house. I’ve posted this before, but I’ve always enjoyed this crankset as far as the CNC style goes…
Evidently they’ve delayed the release because it didn’t meet their performance parameters. Something like $900 for the thing, minus rings.
