How to choose a road bike that suits you

How to choose a good bicycle The main reason for choosing a bicycle is to see if it is a good frame, secondly, whether it is composed of good parts, and thirdly, whether the assembly technology is good. Only when these three factors are scientifically combined can it be considered a good bicycle. 一、 Frame: 1. What is the frame? The frame is equivalent to the human skeleton, and all kinds of bicycle parts can be installed with the frame. The frame is made of iron, aluminum alloy and other materials, and the angle formed by the length of the tube affects the characteristics of the overall bicycle. For example, bicycles that ride in a straight line, bicycles that are easy to turn, and bicycles that ride comfortably, etc., many of these factors are determined by the frame. 2.How can it be considered a good frame? Lightness, firmness, and flexibility are one of the goals pursued by the frame. In order to achieve this goal, it depends on the craftsmanship of each frame manufacturer. For example, whether the designed frame is designed according to the strength and characteristics of the material, and whether the welding process is mature. These all directly affect the appearance, strength and elasticity of the frame. The more important thing is to spray paint. A good frame is evenly painted and sprayed with 3-4 coats of paint. Don't underestimate the spray paint, good spray paint can make the bicycle easy to maintain and not easy to rust. If you use a frame that does not meet the above requirements for loading, it is possible to produce a bicycle that cannot ride in a straight line or is difficult to turn, or a bicycle that will retreat quickly. 3. What materials are made of the frame? The most are iron frames, but iron frames are also divided into chromium molybdenum steel, high-strength steel, ordinary steel, etc. The iron frame is added with other extremely high proportions. After adding these other components, it can be made into thinner pipes. Makes the overall frame lighter. Recently, frames using materials other than iron, such as aluminum alloy materials, have appeared without reducing their strength. In the bicycle race, there is a frame made of titanium metal carbon fiber material. 二、Components 1. What are bicycle parts? Various parts mounted on the frame have their own functions. For example, the brakes are used to stop the bicycle safely; the pedals are used to transmit power to the wheels, etc., production and sales of these Specialized parts factories are called bicycle parts manufacturers. Well-known parts manufacturers develop new products every year, and these products are provided to major bicycle manufacturers and then appear on the market. 2. What is the best bicycle part? Simply speaking, it is both light and strong, and the performance is better. It is easy, safe and convenient to ride a bicycle because of these conditions. But to achieve all the above conditions, good materials are needed. Therefore, bicycle parts are often a specific factor that affects the price of bicycles. The best is the parts that can participate in the Olympic cycling competition. The best materials are used in terms of strength and weight.
