Yeah, aluminum scares me as much as carbon does. They both fail fast. A friend of mine was going downhill on pavement one night when the right side of his Al bar just came off. It didn't bend or fold first, it just popped off. Luckily he wasn't going fast and there was no traffic. The manufacturer later recalled that bar, which raises another point. If any part made by a major manufacturer was a real threat to the user, it would get recalled if it was released at all. No company wants to kill its customers. Except maybe those insane weight weenie companies in germany.
