Genuine question; how do you guys feel comfortable buying wheels off an 'unknown' brand from AliX? I stick to the big names and even then I feel so hesitant handing over my money. Paypalling money to ProX was stressful!
Truthfully, I've never had issues buying name brand (for AliX standards) and if I did I was well taken care of.

It very well may, but when they price their products as much as a new bike, it puts those products out of reach for 90% of the cyclists out there.

Also, I understand a little more about why you see these products offered and they seem exactly like their name brand versions. When you contract a Chinese firm to manufacture and build your product, there is a clause in most contracts that says if you are late on payments, your intellectual property rights are forfeited. I don’t think that’s the deal with the cranks at all, they look a little like 5dev but they are obviously not. The derailleur looks exactly like Ingrid and included documentation from Ingrid. I think it looks like a Walmart mountain bike, not a fake anything, people hardly know what derailleur is what. In fact, because of my hokey paint job I was thinking of putting Hyper or Huffy stickers on the down tube as a theft deterrent.

Could you recommend any high-quality suppliers?

I thought the spacers were in two pieces....

Also, I can't fit the conical split ring anywhere. That's a standard part for centring the steerer on 99% of normal headsets.
