>>1039435>As mentioned before however, aluminum and steel often give you a warning or bend before completely disintegrating.Complete gobbleygook. If a fatigue crack starts in an area you can't see or never inspect (junction of the steerer to the fork crown, inside of the crank spider), you're never going to see it or hear it until near-instantaneous catastrophic failure occurs.

The issue I have with carbon being used on bike frames is the lack of abrasion resistance, and the lack of strength to impacts. It's fine for race bikes. I'd never want to own a townie or touring bike made out of carbon though, where a poorly-attached bag or bungie cord can abrade through the frame in a day's worth of riding.
