Phil on the cracked frame: 3/4 through chainstayPdxMark

"Armstrong crossed the line on Monday not knowing that his rear chain-stay tube on his frame was three-quarters fractured in the fall. Had it snapped, he would have crashed with potentially race-threatening consequences."

unlike metal failure would not be as spectacular. Carbon fibers are holding crack together, it just becomes noodly.

Second hard to imagine someone crashing b/c of chainstay failure going uphill. I rode a double century with a guy who's chainstay separated ~30mi into ride. He was your typical 6'2" 210lbs gorrilla, pulling paceline at 26-28mph.
That makes sense...PdxMark

It seems that the load on the seatstay on that side would increase dramatically. So long as the seatstay held, the rear wheel would at most wobble a bit, giving a noodly feel. And the frame alignment (on a metal frame) would take a beating, but what does that matter under the circumstances. Though, once the seatstay failed under the extra load...
