I used to kid the neighbor across the street when he had his broken Honda Civic up on blocks repairing it again and again. I told him that he could break an anvil. I had a nice old steel Bianchi that got killed by a car. The frame was toast, so I got an aluminum Nashbar frame and transferred the parts from the busted Bianchi. It just wasn't the same, so I sold it to the neighborhood kid. He managed to a strip the BB threads, and break the aluminum seat post, neither of which ever gave me any problems. He's grown up now, and a father of twin girls. Hopefully he is done breaking things.
