1. Mountain bicycle purchase skills 1: frame material
The main materials of the frame are steel frames, aluminum alloy frames, carbon fiber frames, and nano -carbon frames. Among them, the weight of the steel frame is not light. Rust, technology has been eliminated, but there are still very classic handmade steel frames that are dreaming of many people's dreams; aluminum alloy frames are much lighter than steel frames, but the strength has been improved. The first choice for running a thousand dollars; carbon fiber frames are mainly used for various competition cars, which are relatively professional and high -end materials; nano -carbon frames have stronger durability and lighter weight, and they are also high -end materials.
2. Mountain bicycle purchase skills 2: Tire
Human -character tires appear as guided tires, and they are very good. The horizontal font tire appeared as a power tire, which is characterized by strong grip. Big floral minced floral tires are used for ride on hard roads, and small florals are used for soft pavement riding. Bald tires are suitable for long -distance hard road ride. The universal tire is the product of the industrialization of the product, with both orientation and grip.
3. Mountain bicycle purchasing skills three: gear transmission system
The more gear gears, the faster it will make people ride. The intention of multi -stage variables is to make the rider adjust the speed of the transmission according to physical or road conditions, so that the stamping is maximized. Generally, the speed of 10-18 sections is used for commuting travers, while leisure, exercise is recommended to have a 21-24 variable change. If it is climbing or competition, of course, you must choose a 27-30 transmission. The so -called transmission number refers to the large tooth plate controlled by the left hand and the flywheel controlled by the right hand. It's 27. At present, both highway cars and mountain cars have evolved to 30 gear transmission, and even Campagnolo has launched a 11 -speed flywheel to make the road vehicle advanced! The complete transmission system kit includes the front chain, the rear dial chain, the transmission handle, the big teeth, the big teeth, the big teeth, the big teeth, the big teeth, the big teeth, the big teeth, the big teeth, The trail group, flywheel, chain, flower drum, brakes and so on. The fastest way to distinguish between bicycle levels is to depend on which level of the matching transmission system is.
