Shimano's kit, design details, appearance, durability, performance and quality control level. , are well-known in the industry. Go to various cycling forums and ask. ? Mountain bikes and road bikes are subdivided into entertainment level and professional level to meet different needs from novice, advanced, feverish, amateur to professional. For example, by 2020, the mountain bike kit will have four entertainment levels (aluts for entry-level entertainment, acera for mid-level entertainment, alivio for high-end entertainment, m4 100 for Deore/Kloc-0) and six professional levels (M 51Kloc-0/speed for entry-level entertainment). 12 speed m7 100, professional high-end XT? M8 12 speed m8 100, professional D 12 speed m9 100 and electronic variable speed Di2). Let every rider find the right level in price and performance. ?
Shimano's kit is also a necessary equipment for athletes in international competitions (including the most used small S and S), especially the first-class road cycling race sponsored by the International Cycling Union (the Tour de France has a history of 100 years, and the five classic races are cross-country races, among which the Paris-Rube race has a history of 65,438+0,30 years. Tour de France and Paris-Rubeus Championship are what every professional needs or dreams of), XC (Cross Country) World Cup Mountain Bike Race, EPIC (Marathon) World Cup, Enduro (All Mountain Endurance Race) World Cup, DH (Downhill/Downhill) World Cup, and road cycling and mountain cycling events of the Olympic Games.
Shimano has R&D institutions in countries with developed bicycle technology and market in the world (North America, Britain, France, Austria, Switzerland, Spain and Australia, etc.). ). And by uci professional players to participate. Shimano's transmission system and transmission system are self-contained. Finger transmission, front transmission, rear transmission, transmission tube, wire core, central shaft, toothed plate, chain and even brake system and wheel set constitute what most riders call "no choice for compatibility". This is also incomparable with the brands below it (they usually only refer to dialing, dialing before and dialing after). Others are made by third-party brands).
The main advantage of choosing the blueprint is that the price of the same level (the same speed level) is cheap. Whether it is a road bike or a mountain bike kit, it can be used for ordinary riding, ordinary folk amateur competitions and ordinary light cross-country. However, compatibility, chain noise, durability, etc. Not as delicious as Shimano's. For example, the blueprint kits reflected by some riders need to be repeatedly and patiently debugged (both Richi with good quality and flywheel with ordinary sunshine are not as good as Shimano in tooth profile and accuracy, and there is also a gap with the shifting cooperation of the chain itself). How to find cheap, easy-to-use and durable goods with the principle of "one penny for one share"?
The industrial aesthetic design of Shimano's previous generation's professional Ding m9000 crank is like a handicraft (the new generation xtr m9 100 can be found by yourself).
Shimano professional high-end XT tooth plate series (right: previous generation 20 13, left: previous generation 20 16, both of which are second-generation hollow cranks, reducing weight and improving pedaling output efficiency). Micro-rotation is not up to the level of 20 13 at present, and Meng Hao, a third-party dental disc factory, is still "referring" to the structure of 20 13, so the following brands will not be mentioned.
The middle GX tooth plate of sram (small S) is like this. Industrial aesthetics is better than Shimano.
Give directions or something, and then dial back. Don't talk nonsense The mid-range GX of the small S is so fashionable, and the shift is crisp and neat, not to mention its high-end XO 1, XX 1 and so on.
XT of big S? Finger dialing provides three structures, or 1 1 speed. It is also clean, fast, two-way release, fast forward four gears, fast backward four gears function is very fragrant, and the price is high.

There is another factor. Flywheel is an important factor affecting shift smoothness. Both Shimano and Su Lian have their own years of racing experience and computer software aided calculation of tooth profile, one of which is Shimano's "tooth loss" and Su Lian's "fin tooth" (a change and improvement of tooth loss). Other suites do not have this design, one is patent protection, and the other is complex technology and high price. However, if there are residual teeth and missing teeth, the shift speed is fast, the weight is light, the chain noise is low, and the wear on the chain is small.
Also, pay attention to Shimano's flywheel. The tooth profile on each piece has a variety of components, which are complex and precise, which also improves its speed change and shifting performance, especially suitable for road vehicles and Shimano kits in uic Grand Tour.
The XT 10 speed flywheel of Shimano 2013 is sharp and complicated in tooth design and technology. Up to now, there are no other brands that can be designed and manufactured except Quack and Campagnolo. ? As for the central axis, chain and the like, not to mention.
