My extensive research has found this. Carbon should not be exposed to temperatures above 65 degrees fahrenheit it will melt. Steel will spontaneously rust and fall apart if it exposed to water. Aluminum will bend or crack if struck by any object larger than an eyelash. Because of these features I own bikes made of all materials.

Carbon for cold rainy days.
Steel for dry days above 65 degrees
Aluminum for my trainer...this way nothing can harm it (I wear eyelash catching goggles to keep it from being damaged).
