Bad luck with the crash but on the plus side you escaped without serious injury.

Interested to see that the fork/headset and wheel don't show any obvious damage but the top and down tubes on the frame have failed completely. There was a thread on here a while ago by someone who had had his lht frame fail after hitting a pothole. In both cases I am surprised at how bad the damage was to the frame. I know the bikes are popular but do these cases raise questions about the quality of the frames? I was surprised to see that on a relatively expensive bike they use a generic CrMo tubing rather than a branded tubeset from reynolds/colombus.
