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.
Running along the inner edges of a tire are the beads. Beads are high-strength steel, coated in rubber, which gives tires strength while also helping to hold the tire to the wheel. The body of the tire is actually made up of fabric, not rubber. The body is built from layers of fabric (each layer is called a ply).The plies aren't your run-of-the-mill cotton fabric; they're usually a strong composite material.The plies are coated with rubber, not only to help them hold air inside, but also to help them bond to the other parts of the tire.he final part of the tire is the tread. The tread is on the outer edge of the tire. Like the sidewall, it's made of a mixture of natural and synthetic rubber.
