dynaryder, I agree.
If a bike it put together so bad that it's a death trap, then there is a big problem. As I have said and well allways say. If you buy a bike from any place (even a LBS) go over the whole bike and check it out for your self. The LBS mechanic are just people and may over look something just as well as any person might. If it's a Wai-Mart bicycle then it's up to you to adjust it. If it needs parts, then take it back and make them make it good.
