At first glance, this frame is good in workmanship and painting, and the small auxiliary handle is also quite practical. But looking at the configuration in detail, I think the big problem of this car is the unreasonable configuration. It is said that although the price of 2500 yuan can't be used as high-end accessories, it is not enough.
1, as an 8-speed flywheel, HG30-8, an almost outdated thing, is still used in new cars. At present, it is at least time to use HG3 1-8. Hollow teeth, higher workmanship and weight.
2. It's out of date to use only one M4 10 to make a bluff, and RD-M4 10 (after dialing) is just one of the M4 10 suites. Including gear shifting, front gear shifting, rear gear shifting, flywheel, chain, toothed plate, and even front and rear flower drums and brakes, the gear shifting parts should be aligned to give customers a complete experience.
3. It is economical and practical to use the cutting-edge toothed plate, but in my opinion, it is just another distraction. It is just another failure to use the cutting-edge ownership of SRAM to enhance the value of this car. I don't understand whether you want users to experience the practicality of SRAM or the exquisiteness of Shimano. It is better to use M 19 1(48-38-28T) directly.
This car is a mess. It seems that users want to upgrade when they buy it. In that case, you should at least minimize the upgrade cost of future customers. Why should EF65 be changed as a whole? For the sake of the user, you should use the index finger.
5.BB5 is another thing that is not good at spending money. With this money, you can use the M442V brake, and the saved money can be put on the fork locked by oil pressure for users to experience.
..... All right, let's stop here. Finally, it is stated that this article is not aimed at M brand, but only at cars. exceed
