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.
Historically, the most common material for the tubes of a bicycle frame has been steel. Steel frames can be made of varying grades of steel, from very inexpensive carbon steel to more costly and higher quality chromium molybdenum steel alloys.rame size was traditionally measured along the seat tube from the center of the bottom bracket to the center of the top tube. Typical medium sizes are 54 or 56 cm (approximately 21.2 or 22 inches) for a European men's racing bicycle or 46 cm (about 18.5 inches) for a men's mountain bicycle.
