Don't get them.
In the SR store, it comes out to $31 shipped for 2 wheels.
Just buy an eagle instead. It will last you longer than 2 Yak metalcores. Trust me.
1) I don't know how much they weigh. But, they are light as hell.
2) I'd think about $35.
3) They come raw, not powdercoated.
4) Powdercoating costs as much as the powdercoater charges. So, just look around and you'll find someone who does it.
