I love carbon, but would never consider it for bar or stem on my cross bike. At a race yesterday, one of my teammates broke her carbon bar -- during the race. Luckily, she wasn't hurt, but at the right/wrong moment, that break could be disastrous. She bought the bike used from a pro rider and my guess is it probably saw a few crashes in the past, compromising the integrity of the bar. It broke while she was just riding.

Glad you're okay, SheFly!
