Athletes wishing to push themselves to their physical limits in biking take care when choosing the material for their bicycle frames. Aluminum is one of the common materials used, particularly in road bikes on the low end of the price spectrum. Lightweight and stiff, aluminum is an ideal frame material; however, due to its rigidity, aluminum tends to sacrifice a comfortable ride for a lighter bike.
In recent years, carbon-fiber frames have emerged as the top choice for competitive cyclists. Carbon-fiber frames are lightweight and aerodynamic, but the quality can vary widely based on the type of carbon used. On the opposite end of the weight spectrum, steel frames have earned a reputation for durability and comfort. Although steel frames are significantly heavier than their aluminum or carbon counterparts, they have a greater ability to survive spills with minimal damage and traverse rough roads smoothly.
