affirm the former. Let's talk about brand history, positioning and influence. Shimano (hereinafter referred to as "Big S" in the industry) has become a leader since it replaced no1 (Italian) Campagnolo in the 198s. He and sram (hereinafter referred to as "Small S"), which ranks second, occupy about 7% of the global market for speed change kits (the other 2% is Campagnolo, which has now become a niche, and the fourth-ranked microshift, and the remaining 1% is other). Shimano has many patents and innovative technologies of zui (for example, SIS positioning technology in those days, the technology of replacing beam transformer with hand-changed head of road vehicle, special kit for mountain bike and road vehicle, special kit technology for multi-functional off-road vehicle, hollow crank technology, UG positioning and improved HG positioning to improve gear shifting sensitivity and reduce chain noise and friction, and current HyperGlide+ positioning technology, Electronic transmission technology and so on have played an important role in promoting the development of bicycles and the progress of sports competitions (this is not what I personally said, but the unanimous view of bicycle media, industry, athletes and players). (Of course, SRAM is also very good. For example, its wireless electronic transmission technology comes from behind, and the whole has its own advantages and disadvantages with Shimano. Don't spray me, little S fans. I'm just answering the questions on the subject. ? Let's talk about market applications. The whole vehicles of major brands, whether it is the upstream lightning (S-WORKS and SPECIALIZED), TREK, Cannondale, scott, BMC, Plum Blossom (Colnago), Cervélo, etc. or the first-line Giant, Merida, CUBE and NORCO.
shimano's kit, design details, appearance, durability, performance and quality control level are all well-known in the industry. Go to various cycling forums and ask. ? Both mountain bikes and road bikes are subdivided into entertainment level and professional level to meet different needs from beginners, advanced, feverish, amateurs to professionals. For example, the mountain bike kit, by 22, there will be four entertainment levels (aluts for entertainment entry, acera for entertainment mid-range, alivio for entertainment high-end, m41 for deore 1-speed for entertainment ding) and six professional levels (m51 for deore 11-speed, M61 for professional entry, and SLX for professional mid-range? 12-speed m71, professional high-end XT? 12-speed m81, professional ding XTR 12-speed m91 and electronically variable 11-speed XTR Di2). So that every rider can find a suitable level in terms of price and performance. ?
shimano's kit is also a must-have for athletes in international competitions (including Xiao s and Campagnolo, where shimano is used the most), especially the first-class road cycling race sponsored by UCI (International Cycling Union) (three Tour de France, five classic races, namely cross-country race, with a history of 13 years). Tour de France and Paris-Rubeus Tournament are required or dreamed of by every professional player), XC (cross-country) World Cup for mountain biking, EPIC (marathon) World Cup, Enduro (all-mountain endurance) World Cup, DH (downhill/downhill) World Cup and road bike and mountain bike events of the Olympic Games.
Shimano has R&D institutions in countries with developed bicycle technology and markets (North America, Britain, France, Austria, Switzerland, Spain and Australia). And by uci professional players to participate. Shimano's speed change system and transmission system are self-contained, such as finger shift, front shift, rear shift, speed change tube, wire core, central shaft, tooth plate, chain and even brake system and wheel set, which constitutes what most riders say is "no choice in compatibility". This is also incomparable with the brands ranked below it (they usually only refer to dial, dial before and dial after). Everything else is made by a third-party brand).
the main advantage of choosing the blueprint is that the price of the same level (same speed level) is cheap. Whether it is a road bike or a mountain bike kit, ordinary riding, ordinary folk amateur competitions and ordinary light cross-country are possible. However, compatibility, chain noise, durability, etc. are not as good as Shimano's. For example, the blueprint kits reflected by some riders need to be repeatedly and patiently debugged (whether the flywheel is made of better quality Richi or ordinary Sunlight, its tooth profile and accuracy are not as good as Shimano's, and there is a gap between it and the shifting cooperation of the chain itself). How can you find cheap, easy-to-use and durable goods with the principle of "a penny for a share"?
Shimano's previous generation's professional ding-class XTR m9 crank has a handicraft-like industrial aesthetic design (the new generation xtr m91 can be found by itself). Shimano's professional high-end XT tooth plate series (right: previous generation's 213 model, left: previous generation's 216 model, all of which are second-generation hollow cranks to reduce weight and improve pedaling output efficiency). Micro-rotation can't reach the level of 213 model at present, and the third-party dental disc factory Haomeng is still "referencing" the structure of 213 model, not to mention the brand below it.
The middle-end GX dental disc of p>sram (small S) is like this. Industrial aesthetics is better than shimano.
don't talk nonsense about what to dial after dialing. The mid-range GX of the small S is so stylish and the shift is crisp and neat, not to mention its high-end XO1, XX1 and other < P > XT of the big S? Finger-dialing provides three structures, which is also an 11-speed shift. It is also clean, fast, two-way release, and the functions of fast-forward and fast-backward four gears are very fragrant, which is far behind the micro-rotation. Of course, the price is also high.
the overall performance, industrial structure and ergonomics design of XT-11 high-speed rear-shift, as well as its fast gear shifting and gear reversing performance in severe bumps, are also beyond the reach of micro-rotation and below at present, and of course, the price is high. In addition, professional and amateur mountain bike players don't use XT kit to compete (both use XTR), and players use XT more.
one more factor. Flywheel An important point that affects the smoothness of shifting. Both Shimano and Sulian have their own many years' racing experience and computer software aided calculation of tooth profiles, one of which is Shimano's "tooth loss" and Sulian's "fin tooth" (a change and improvement of tooth loss). Other kits don't have this design, one is patent protection, and the other is that the process is complicated and the price is high. However, if there are residual teeth and missing teeth, the upper and lower gears are fast and light, and the chain noise is low, and the wear on the chain is small.
In addition, pay attention to the flywheel of Shimano. Each piece of the flywheel has a variety of tooth profiles, which are complex and sophisticated in technology, which also improves its variable speed and shift performance, especially for road vehicles, and Shimano kits at uic Grand Tournament have the same reason at most.
the XT 1-speed flywheel made by shimano in 213 is sharp and complicated in tooth design and technology. Up to now, there are no other brands that can be designed and manufactured except Quick Link and Campagnolo. ? As for the central axis, chain and so on, let alone
