It is, and it's likely the worst frame you'll ever see. The "lugs" are stamped steel "halves", pressed onto the tubing and welded with some kind of electric process, I'd guess either MIG or stick. The welds are horrible, and there's slag everywhere. And there are gaps between the lugs and tubing. I cleaned everything up and filled the gaps with brass, but I can't imagine very many people are going to want to go to that trouble on a $90 frame. And of course it still handles terribly. Oh, and the bottom bracket shell is some wacky width, like 78 mm, so nothing but the (godawful) stock BB will work. I ended up spending an hour or so with a facing tool, removing acres of steel in order to fit a more normal bottom bracket, only to discover that the bottom bracket shell appears to be composed of an outer shell with inner threaded sleeves brazed into place -- and the sleeves are misaligned, of course, so it's impossible to properly install the bottom bracket no matter what you do.

I regret the entire project, though I am at least glad to have filled that particular void in my knowledge. Overall, though, I'd prefer to have my money and time back. Oh well...
