Carbon Frame vs Aluminum Frames

 The bicycle frame is a vital part of the entire bicycle, and the material of the bicycle frame on the market is also varied. However, the most common ones are aluminum alloy frames and carbon fiber frames. So, for the two common materials, what should we choose when we buy?

Aluminum alloy

Aluminum alloys are more common than carbon fibers on the market. Because, whether it is an entry-level aluminum alloy frame or a professional-grade aluminum alloy bike, it is more common in the market.

That is, no matter which level of bicycle. The material of aluminum alloy will be used in bikes. As the common material on the market, and its biggest advantage is that light weight, simple workmanship, and relatively inexpensive.

The strength and rigidity of aluminum alloys are relatively lacking. This can be changed by the unit area of the object. Even if it is used for a long time, the appearance will not change much.

Because aluminum is originally a relatively corrosive material, there is almost no aluminum that is not oxidized in the air. When aluminum is placed in the air, then an oxide film is formed, and the oxide film reaches a certain thickness to prevent rust.

The fatigue resistance of the aluminum alloy frame is relatively poor. The strength of the aluminum alloy will change if it use frequently. Of course, not all of them are the same. According to different aluminum alloy materials, the rate of change of strength is also different.

Carbon fiber

Carbon fiber is a material formed by weaving carbon. The price of carbon fiber bicycle frame is relatively expensive compared to aluminum alloy. Because carbon fiber is more expensive, it is often used in professional cycling competitions.

The carbon fiber frame is not only light, but also better than aluminum alloy in strength and rigidity. When selecting the frame, you should choose according to your actual situation. The aluminum alloy is suitable for high-strength cycling, and the carbon fiber is suitable for speed riding.
