Four popular bicycle frame materials are steel, aluminum, titanium and carbon fiber. Beryllium, Metal Matrix Composites and other materials have so far demonstrated limited practicality in bicycle frames. Mysterious and seemingly miraculous beryllium is one-third the weight of aluminum and six times as stiff as steel.his is another reason to look for metal frame parts (such as dropouts) that are made of titanium rather than aluminum if you are shopping for a carbon fiber bike. Discontinuity of materials can create stress-risers where the carbon fiber meets the other material. The stress-risers can lead to failure.
The same is true in many respects of aluminum. Steel on the other hand, will bend before it breaks, resulting in a far more resilient frame. There's a misconception that steel bike frames are heavy, and aluminum frames are light. Not surprising, we make bridges out of one, and soda cans out of the other. And while it's true aluminum is lighter by volume as a metal, that property doesn't tell us the whole story.
