Common sense of bicycle configuration

First of all, let's talk about the main components of xc mountain bike: frame, wheel set, front fork, transmission and speed change kit, three-piece set, bowl set, seat bag, handlebar cover, pedal, inner and outer tires of inner tube and other supporting kits. For beginners, the most intuitive configuration difference is the transmission speed change kit. The mainstream is Shimano in Japan and Speedlink in America. These two brands, like intel and AMD in computer processors, occupy half of the speed change, and their product series classification is very clear. Like Shimano deore, it is called professional entry level, and there are slx, xt and xtr levels, such as brakes, cranks and forward and reverse dials. All the parts have logo, but the more difficult ones are the center shaft, chain and flywheel, which some novice brands can't see. In order to save costs, some low-priced cars simply add a 1 1 speed miscellaneous brand flywheel and a tall xt rear dial. At first glance, if you know something about fur, you will think, wow, such a conscience. Two thousand cars have xt, but in fact, the performance of this hybrid car is not as good as a low-grade one. The theoretical configuration of fork is nothing more than pneumatic fork >: oil spring fork > Of course, there are many technical supplements to the spring front fork, such as locking, sectional locking, intelligent locking, adjustable stroke, pre-tightening and turtle and rabbit adjustment. The control methods are wire control and fork shoulder control, and the air fork has single and double air chambers. The so-called front fork inner tube coating technology and cone tube technology all add points to performance more or less, and the price will naturally rise. You can learn more about the brands of Qiancha, such as Santuo, Manetho and rockshox. Braking is also worthy of novice attention. After all, braking fast is safe. Braking can be divided into V-type brake, cable disc brake and hydraulic disc brake. Mountain bikes have almost eliminated V-brakes now, and steel wire reels are rarely used. Braking is actually included in the big kit of transmission and transmission series, but it is often difficult to apply the big kit to the whole vehicle. The brakes may need to be shrunk, and there are many brakes. Not to mention Shimano and Su Lian, Yan Hao, Magula and Su Lian. I5 is as easy to distinguish! Wheel alignment is very important, but compared with metaphysics, these two low-priced cars for novices are not much better anyway, and they will either be modified or replaced in the future! The remaining three sets, bowls, tires, seat bags, pedals, handlebars and conduits, are all small pieces, but these insignificant things have a great influence on handling and comfort. Low-priced cars are rubbish. It's not expensive to buy a suitable one for a change. The seat airbag, handlebars, pedals and tires in contact with the car body should not be vague, and I really feel it.
