How about these quotes from the first page: "She spent a few days in the hospital over this. On a normal ride with friends and frame let go" "This shot is of a friend’s seat post sometime after he adjusted the saddle height" "Just 'popped' when I stood up to do a fast sprint" "I managed to mostly avoid it but got pushed into a barricade and when I looked down my bike was in two pieces" "I was sprinting through busy downtown San Jose traffic with a guy a fixed gear when my seatpost went "ka-RACK." Fixie kid laughed." (well that's just the first half of the page, will stop pasting now)

I'm not sure what your point is? Yes, people get injured when they have bike crashes. Yes (as I noted), carbon can fail. Metal can too! [1] is a much better survey of random broken bikes than bustedcarbon. [2] is a good summary of the hysteria around breaking carbon frames and some of the facts. Here's a pic of a broken titanium (!) bottom bracket: http://www.pardo.net/bike/pic/fail-001/FAIL-143.html http://www.pardo.net/bike/pic/fail-001/FAIL-143.html Assorted mostly steel and aluminium broken frame pics: http://www.pardo.net/bike/pic/fail-001/FAIL-167.html http://www.pardo.net/bike/pic/fail-001/FAIL-167.html [1] http://www.pardo.net/bike/pic/fail-001/000.html http://www.pardo.net/bike/pic/fail-001/000.html [2] http://isolatecyclist.bostonbiker.org/2011/02/21/carbon-bicycle-forks-cautions-facts-and-misconceptions/ http://isolatecyclist.bostonbiker.org/2011/02/21/carbon-bicy...

  I guess one point is that carbon fails catastrophically more often, your metal links point to breaks where the bike still stayed in one piece. Yeah, they're not unheard of with metal bikes, but much more rare. The injury quote was about her getting injured because the carbon frame just fell apart with no warning (no crash, except after the frame failure of course).

    I guess one point is that carbon fails catastrophically more often - There are "scientific" reasons why these things break for no apparent reason. b/c carbon is prone to developing "flaws", not all of which are visible (to naked eye). These happen either through previous impact damage or fatigue cycles. - Carbon failure can cascade (snap...snap...snap...). Once the structure is compromised, the lack of sheer strength combined with different-from-design force vectors...are not good (a two-sided trianle = wishbone...) Look at how many carbon parts had multiple, complete failures. - A metal frame will dent or bend if damaged; it doesn't hide flaws nearly to the same extent. You might get a hairline crack, but unlikely 3-4 snapped cross-sections. -Obviously, getting hit by a truck or whatever doen't matter what you are riding.
