It could be due to over-tightening the peg, but most likely it is due to the fact that the peg was manufactured using aluminum forging process. Whereas forged aluminum is harder, it is more brittle and less giving. On rare occasion, forging can result in creating a hairline fracture that weakens the aluminum structure over time and results in a crack and breaking. So far, I’ve seen it happen only once myself, and it was in this photo. Nevertheless, too bad that it has happened, and hopefully this happened near a dealer location or a house.
