From Jon:
Just 'popped' when I stood up to do a fast sprint around a slow rider on the local W&OD bike trail.

Went racing yesterday in the “Ride for Life” at Centennial Park in Sydney. Had had a good week of training with about 350kms under my belt from riding to Terrigal on Tuesday and so felt good for the ride. Coming into the second last lap was in the front third of the group when some guys in front touched wheels and created a domino effect that took out about 20 guys with 5 ending up in hospital and one with a punctured lung. 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 afixed gear when my seatpost went "ka-RACK." Fixie kid laughed. I mighthave said some naughty words.


He hit a bump in the road and cracked off one of his carbon aero bar extensions, and unfortunately it was the one with the controller for his rear derailleur attached.
With the bar dangling from the electric wire used to shift his Shimano Di2, and more tight turns, speed bumps and descents in the coming three kilometres, Tuft continued to plow ahead, much to the amazement of his directeur sportif, Steve Bauer.

I have a cannondale moto carbon bike, and I found suspected ‘CRACK’ or could be simple painting problems on both side of main pivot links.
Plz check photos…..
I was puttering -- 8 KM/H if that -- down a 1 1/2 meter gravel embankment when my front wheel washed out and down I went. Basically I just toppled over. Having hopped clear before the bike became acquainted with gravel (visible inside the bar on some photos), there was no weight on the carbon bar other than the bike's at the time of the impact. Astonishing that such an innocuous spill could result in such a failure. Or perhaps not. I'm grateful that the bar's demise didn't come under more painful circumstances.Carbon and downtube shifters is a pairing you don't see too often.
I've since reconsidered the merits of carbon components where recreational and utilitarian cycling is concerned. No wonder.

Attached is my effort at recreating the recent Mark Cavendish crash in our club crit last night (Ormeau park, Belfast, Northern Ireland). Actually, I didn't even get the chance at a of reckless sprint. Rather a case of some loose gravel on a tight corner and me sliding into a kerb. First lap too, ragin!

@bustedcarbon here's some from last nights racing http://twitpic.com/1lbwxv Look 585 I think

I heard a pop in back of the bike but proceed to ride it for about another 10 seconds. Until Jeremy yelled at me to stop and check the wheel. I though it I have broken several spokes but no this was the end result.Read the full story on his blog. My wife has the same bike, and she broke the rear triangle as well, but in a different location. Gary Fisher did warranty hers, and she even got him to sign it.
