Just to be clear. Few frames are made outside one of the China's and few components outside Asia. Being made there is no indication of quality as some brands make sure they're getting good stuff and others don't. As always, cost is a reasonable indicator though also, as always, it's not absolute in that you can pay too much for rubbish or you can get get a bargain.

As far as 8bar goes, I've got no idea as I have no experience with them, I'm just commenting on the source question.
