Point taken, but this is the first fork I've seen that failed this way. Everybody's allowed to make a mistake every once in a while, right? The brazing on the new one looks much better: there's a significant, even amount of brazing material all around the steer tube-lug interface.

BTW, you probably already figured this out, but this fork failed slowly. It let me know it was broken and held together long enough for me to ride back home (at 5mph), resulting in zero bruises. Now I'm even less likely to buy a carbon fork than I was before.
