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.
Steel vs. Aluminum Bike Frames April 22, 2014 Most city bikes are built on either steel frames or aluminum frames, and which one you pick will impact the quality of your ride and the life of your bike. Read on for the how and why, and we'll help you navigate the materials market. Aluminum frames are generally stiffer than steel, resulting in a harsher ride.
