Default New Carbon Fiber Information

A friend who speaks Italian spoke with a bike builder in Italy who spoke to Ernesto Colnago. He verified that the problem with Carbon Fiber aside from possible manufacturing defects is that the resins grow more and more brittle with age. After two years or so they can grow so brittle that the ultra-lights can fail at any second. This is why Colnago will only give two year warranties and why they build their "light" bikes considerably heavier than other manufacturers.

Have a good ride on your CF when you can get the same weight with an aluminum frame.

Colnago doesn't have the know how to build light CF bikes that last and/or stiff enough so the answer of Ernesto doesn't surprise me.
Something like Kodak that didn't know anything about digital camera's.

Show me an aluminum frame of 850 grams. Any frame lighter than 1300 gram I prefer the CF one. YMMV.
