Handlebar vs Chainstay

Here's a bizarre story from Ryan:

Here's a photo of the left chainstay of my Specialized Tarmac. This happened when I was racing the Ski & Bike Kare Criterium which was the last stage of the Steamboat Stage Race. On the second to last lap I had what I think was the handlebar of a crashing rider smash right into my left chainstay. It all happened behind me so I'm still not sure what happened exactly. I managed to not go down during it all but my race was over since my rear tire exploded when it all happened.

Who knew that was even possible.
