What's the scoop on this IRD brand? I was looking at their Defiance crankset, because it's pretty economically priced, and looks really cool.

For the threaded headset, you wrote "Hands-down one of the finest threaded headsets on the market...". On another website, I read their bottom bracket is comparable, and if not better in some aspects to Phil's, yet it's about half the price.

So are they actually premium quality at a mid-level price?
