I try not to hit things head on. That being said, the Chinese have a long history of putting junk into everything they make. They've even been caught putting plaster and asbestos in the pills they sell as medicine. By the way, have you seen Pepcid AC on drugstore shelves in the last few years? Not the cardboard little pills but the bottles. I haven't been able to find it for three years. I asked the pharmacist and he just fell silent. I smell a cover up. The bike frame in question is probably made from tin and pig iron.
