You get what you pay.
20,000 cars and 200,000 Volkswagen cars, including meticulous craftsmanship, handling and comfort. 300 yuan, the old man, Huawei's smart phone costs 3000 yuan. There is a huge gap between famous brand shoes in 70 yuan and Nike basketball shoes, running shoes or famous brand shoes in 700 yuan in terms of applicability, durability and comfort for different purposes, and the sense of high-grade clothes. You must know all these examples, so cycling (which is also a very advanced industry, with many international large-scale competitions), although you are not familiar with it, is the same.
? In the 300 yuan, the workshop uses ordinary steel and steel pipes, or uses recycled aluminum. According to the structure and style of a brand, it is made by hand cutting and welding with simple equipment. They don't even know what type and use of bicycles they produce, nor do they know the professional "frame geometry", and there is no "highly suitable" size. Accessories are nameless. Store-after-sales-warranty unified management? No brand official website? No. No security certification. If something goes wrong often, you have to fix it yourself. If you can't fix them or hurt yourself, you will feel unlucky.
3,000 yuan is a big name among international first-line and domestic first-line and second-line brands. At least it is also a brand recognized by cycling enthusiasts and knowledgeable people, and it has a certain popularity. There are specialized or professional design teams, assembly line equipment, automatic welding equipment and quality inspection equipment (such as frame fatigue testing machine and rim strength testing machine, etc.). ), official website, stores and quality assurance. Passed the relevant national safety certification. Finite element analysis, CFD simulation and ergonomics computer software are used in the design. The "Frame Geometry" has been carefully designed and revised, achieving comfortable riding and sensitive control. The main material is high-quality 60 1 1 or 606 1 aluminum alloy, which has been subjected to complicated tri-drawing process or HFS and SPF hydroforming process (such as AluxSL aluminum of Giant and HFS aluminum of Merida). Some of them have been heat-treated by T6, T65 1 to improve their hardness and rigidity (such as 60665438+). As for the variable speed transmission system, rims, spokes and wheels, they are all made by professional manufacturers or well-known brands, such as the 3000 Merida Challenger 300. The frame is a high-quality 6-series aluminum alloy with its own patented technology HFS (Hydroforming), and the speed change kit is a professional entry-level deore (Ximano). The front and rear wheelsets are Vedanta's (Vedanta is one of the international first-line brands of bicycle wheelsets and flower drums), ikon tires of Maxis (Maxis is the international first-line brand of automobile and bicycle tires) and so on. For example, you can find their official website online, such as Ximano, Vidal, Maxxis, Magura and so on. , and view the brand information, history and parameters of various products. Many miscellaneous brands are accessories that don't know where they come from. This can't be done. On the Challenger 300, a lot of accessories were taken out. The price of a brand-name car was above that of 300 yuan, such as oil brakes, such as tooth plates, such as flywheels and chains. Even the center shaft is the mainstream hollow Pei Lin, Simano original BB52, and 55 yuan one (the center shaft of 300 cars is antique square hole bearing, and the scattered beads are ten yuan). ? Small and unremarkable screws: Giant xtc800, Merida Challenger Class 300 car, Simano accessories used are all original nails, imported chrome-molybdenum steel is hardened and rustproof (like two M6 screws for cranks and one in 8 yuan), and other nails are hardened by national standard chrome-molybdenum steel, two or three yuan each. A 300-car is a so-called "steel nail" that costs less than 1 yuan (it rusts in rainy and humid places for a few months, and the texture is soft. It is possible that when you replace parts, the screws are broken and embedded, resulting in the whole part being scrapped).
Many costs and prices are actually hidden, you don't know and you don't see them intuitively, but the safe, durable and comfortable use and the enjoyment of high-quality life brought by "one penny for one thing" do exist in every detail.
Look at basic technologies, such as welding. A few hundred yuan a domestic Laoming brand (the first two pictures, ordinary hand spot welding). Giant 3000 mountain bike XTC800 (Figure 3, welded with thick fish scales).
Look at the foundation, "frame geometry". Don't worry about parameters if you don't understand them, just know the concept. It means that different kinds of cars and models should be used for different purposes, and different sizes should be provided for people of different heights. Different parameters should be adopted in the design (just like clothes and shoes, different types, different versions, different sizes and fatness, providing a variety of choices to make people fit and comfortable). For example, racing road vehicles, climbing road vehicles, long-distance endurance road vehicles, cross-country road vehicles, and flat-handle road vehicles; Leisure vehicles and multi-purpose vehicles for city cars; Leisure hard tail, XC hard tail, forest soft tail, AM soft tail, etc. The frame geometry of mountain bikes is different, so riding off-road bikes and all kinds of soft-tailed mountain bikes at high speed for a long time will make people feel uncomfortable (the geometry setting and configuration are not suitable for long-term pedaling). ? It is very expensive or especially expensive to make these geometric settings.
A certain model of Giant offers four sizes, from 1.55 to 1.9 meters, and people of different heights can find something suitable for them.
Hundreds of pieces like this even include some seemingly famous brands (out of the floor level), and only one size "fits the height of 1.6- 1.9". In fact, everyone who has ridden a bicycle has the experience of "how difficult it is to ride". One of the reasons is that this kind of bicycle is one size and will die, resulting in the upper body, arms and legs being stretched or lengthened.
