If you don’t focus on this field, many people don’t know it. In the past two years, the rise of domestic transmission dishes has played a big role in promoting the new crown epidemic. Because mid-to-high-end products have not been produced in China, factories and freighters have been suspended due to the epidemic, and transmissions are out of stock worldwide, not to mention the rise of domestic products driven by demand in the world’s largest bicycle production base in China.
There are many domestic companies that make transmissions. Compared with the international monopoly of Shimano, SRAM and Compagnolo, there are now micro-rotation, blueprint, Shuntai and Lunfeng in China.
Compatibility first
Shimano has both celebrated their centenary. In the past 100 years, Shimano’s transmissions have been developed from scratch and accumulated a large number of patents, including Speedlink and Compagnolo. If you ride a bike, you will find that although they look similar, the shifting method is different. This is the difference in the patent, and the cable ratio is also different, and even the base (freewheel) of the flywheel is different.
The domestic transmission can even be compatible with two cable ratios
Therefore, if you are domestically made, you can only find a compatible one, such as compatible with Shimano or Speedlink. Their cable ratios are different, because the transmission is not a part, but a whole group. You always have to start with local replacements Only then can. Now the domestic transmissions are compatible with these big brands in terms of cable ratio and so on.
And due to the current supply problem, domestic parts are increasing their market share. At present, kits or parts of domestic transmissions can be seen on many low-end bicycles. And some even go to develop European and American markets first.
Keep up with international trends
What is the current international trend? It is the evolution of the transmission from 11-speed to 12-speed, especially the transmission of road cars. This has brought about huge changes, and 11-speed products are being withdrawn from the market, so domestic transmissions are also iterating. And the speed of keeping up with the times is quite fast.
Domestic even takes the lead in 13-speed
For example, the new product of this blueprint in the picture is named 7020, which is the same as Shimano’s product. The shifting is like a Compagnolo, the shift lever is shaped like a sprint, but the 13-speed, hydraulic disc brakes, and even the rear cassette go ahead, almost the world’s first 13-speed road derailleur kit.
Electric transformers can also be produced
Now the trend of high-end transmission must be electronic transmission. It’s very convenient to shift gears at the touch of a button. But this is only available on mid-to-high-end bikes. You must know that the entry-level electric conversion kits are about 10,000 yuan, and the high-end ones are about 30,000 yuan.
Domestic electric changer, very suitable for the current Gravel car
But the rules of the market game are changing. The domestic Lanxi Lunfeng has launched a 12-speed electric changer, and the price is only more than 2,000 yuan, which is very popular now. Especially for commuting purposes such as BMX and folding cars. Because users still have concerns about the reliability of domestic electric transformers, short-distance commuting will not be affected.
The current domestic transmission you have to say more than finish the race, not to mention. For example, the feel, reliability and many key patents have not been authorized, so there is still a gap, but the key is that the domestically produced ones are cheap and the configuration is not low. If you want to assemble a cheap 11-speed, 12-speed or even an electric bicycle now, Then domestic production is an option that can be considered.
