If thats what you get, ask for it in box so you can build it up yourself. Its really easy, and I can guarantee you'll do a much better job than some schmo at Wallyworld who doesn't really care about their job. And, yea, it should see the inside of a shop for the wheels at least.

And Slim, any 'chain slippage', would be because someone doesn't have proper chain tension, or because they're stupid and are riding around on a bent/broken sprocket. Also, DK isn't really DK anymore.
