Riding friends like the soul of the frame to a bicycle, this is makes sense, because it is compared with other components, it has both requirements of other parts machining precision, also has not possessed by other parts geometric artistry, and all parts need to be done by frame or integrating their functions.
Steel frame
First of all, let's talk about steel frame. Steel frame is the frame pipe with the longest application history among the four kinds of frame materials. It is still active in the field of sports bicycles. The advantage of steel frame has: easy processing, road feeling is comfortable, have the high cost performance material that suits civilian, also have the high-end material material that suits to collect. The disadvantage is that it is not very lightweight and the price is not very beautiful.
The aluminum frame
Aluminum frame is short for aluminum alloy frame, it is a cost-effective frame tubing, we talked about it in front of the contrast steel has the very good price advantage and lightweight, it is these factors that make it gradually replace steel to become the most widely used frame material, now on the market of mid-range sports bike, are almost adopts the frame of the material.
Titanium frame
Titanium frame is short for titanium alloy frame, compared with the first two kinds of frame, its material is more rare (its rare not only reflected in the material, and not easy to process, its welding needs to be carried out in inert gas, otherwise it is easy to crack), so it is naturally more expensive in the price. Since its birth, it has been labeled as high-end, not only because of its high price, but also because of its anti-fatigue performance.
Carbon frame
Carbon frame refers to carbon fiber frame, it is a completely different from the first three kinds of frame pipe, is a new material, it has completely separated from the category of metal materials. Carbon frame was initially applied in high-end competitive road cars. As carbon fiber technology becomes more and more mature, mountain bike frame also begins to popularize this material. However, limited by the price of this material, only high-end models use this frame pipe at present.
