The bicycle is indispensable in the daily life of the vehicle, has the advantages of low cost, simple repair, convenient use, deeply loved by the people all over the world, forming a huge bike consumer market, with the fast development of modern society, the bicycle is not only the traffic and transportation, has the functions of body-building, tourism, competition etc.. And workmanship bike grade depends on the choice of material. Typical low, in high-grade bicycle frame, respectively made of carbon steel, chrome molybdenum alloy and aluminum alloy and carbon fiber. Carbon fiber is a new type of composite material, it has the advantages of light weight, high specific strength, the stiffness of the,

But also can be designed and easy molding, which makes the structure design more efficient.

At present, all countries in the world on the development of new forms, new material bicycle invested enormous human, material and financial resources. The frame is a bicycle frame, which determines the shape and bicycle performance to a great extent. USA, Britain and China's Taiwan has development and production of carbon fiber bicycle frame.

Total carbon: the use of carbon fiber materials, such as MTB 29er rims.

Half the carbon: now a lot of bicycle use carbon fiber + aluminum alloy to manufacturing. For example, a frame, may be on the tube with carbon and other parts of aluminum alloy (carbon using triangular or after) that can be said to be semi carbon.

Package: some carbon frame, handlebar, riser, the crank, fork, sitting rod and other accessories, manufacturers made of aluminum alloy, and then in the coated carbon cloth layer, which is the carbon coating.
