Posted on my facebook page which has several members in cycling was this bit of information. In professional racing, riders are experiencing sudden failure of their carbon frames. It was reported that the failure is so complete, and the frame usually shatters so completely that the frame can be sent back in a small box not much bigger than a box for the wheels. These high end bikes are called "carbon frames" but are little more than some carbon fiber imbedded in plastic. It would be more accurate to call them plastic bikes. In the Tour, almost all pile ups call for a new bike. The days of just straighting out the handle bars on their metal bikes and getting on with the race are long gone.
The dirty little secret here is that racers are pretty much told to keep quiet since the bikes they are given are provided by big name bicycle mfg, and if they speak out, they would be out of racing. The fact here is the mfg make huge profits selling plastic bikes to the wanna be racer boys at very high prices. It all boils down to money as most things do.
BTW I expect to get a lot of hate mail from mfg reps who wont admit who they are, and bike shop owners to also make good money selling the "latest most wonderful" bikes.
