First, the frame: 1. What is the frame? Frame equivalent to the human skeleton, the frame can be fitted with a variety of bicycle parts. Frame made of iron, aluminum and other material composition, according to the length of pipe angle affect the overall composition of the characteristics of a bike. For example, a good bike ride straight, easy switch to bicycles, comfortable riding the bike, etc. Many of these factors are determined from the frame. 2. How can I be a good frame? Light, fast, flexible and good goal is one of the frame, in order to achieve this goal, each frame depends on the manufacturer's process. Such as the design of the frame is based on material strength and characteristics of the design, puma future cat m1welding technology is mature. These have a direct impact on the appearance of the frame, strength and flexibility. There are more important is the painting, even painting a good frame, and 3-4 layers of spray paint. Do not underestimate painting, good painting can make a bike easier to maintain, easy to rust. If the frame does not meet the above requirements to loading, then it is possible to produce a straight line can not turn the bike riding or difficult, or very soon on the back of the bike. 3. Frame is composed of what material? Most of the iron frame, but the iron frame is now divided into Cr-Mo steel, high strength steel, ordinary steel added to the other extreme in the iron frame, adding these other ingredients, you can make such a thin pipe, makes the frame lighter overall. Recently, on the basis of intensity is not reduced, there has been using materials other than iron frame, such as aluminum alloy. There used to cycling of carbon fiber materials, titanium frame. Second, the component parts 1. What is a bicycle parts mounted on the frame a wide range of parts has its own role, for example, is to make bicycle safety brake to stop; Pedal Power is transmitted to the wheels, etc. production and sale of these parts of the specialized manufacturer of bicycle parts factory is called, well-known parts manufacturers develop new products every year,puma ducati testastrettathese products are also provided to major bicycle manufacturers, and then appeared on the market. 2. What is the best bike parts? Simply say that is both light and strong, and better performance. With these conditions because it was easy bike ride, safe and convenient. But to achieve all of the above conditions, you need good material. Therefore, bicycle parts bicycle is often about the price of a specific factor. The best is the ability to participate in the Olympic cycling components. Regardless of weight or strength properties of the best materials are used. Third, the assembly 1. Assembly good parts if the assembly is not good, neither will be as attentive after the design architect, and no experienced craftsmen to build the house, so you live in fear all day long, for fear it will collapse. So, if you do not want the regret later, you should understand that knowledge. 2. Bicycle comfort functions A. Transmission? Many people mistakenly believe that a bike equipped with a transmission speed in order to speed up the ride, in fact, issued by the greatest force people to only 0.4 horsepower. Transmission is to help people easily play this maximum horsepower out of the tool. B. What are the benefits of transmission? Bicycles are generally used in the city, the city actually has a lot of slopes.Puma Repli CatFor example sometimes you will feel when the pedal bike suddenly sink, with the eyes can not determine the slopes more often. At this point, the role of transmission can be fully reflected, so if there is transmission, this time into a lighter gear as long as you can ease the ride.
