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.
Freestyle BMX bikes have come a long way since the days of bodged race machines. The frames are typically made of steel. Heavier, cheaper, high tensile steel is typically used in entry-level models, while pricier numbers get 4130 chromoly tubing and some mid-range bikes offer a mix of the two.efore you buy your BMX, think about the type of riding you want to do â then figure out what weight of bike you need, and whether you need things like stunt pegs. (Stephen Pond/EMPICS Sport). BMX bikes built for racing will be much lighter than freestyle bikes, allowing riders to speed and pop along the track.
