chain

There are many types of chains, but their basic structure is only the following, and the others are all deformations of these types. We can see from the above chain structure that most of the chains are composed of chain plates, chain pins, shaft sleeves and other components. Other types of chains just make different changes to the chain plate according to different needs, some are equipped with scrapers on the chain plate, some are equipped with guide bearings on the chain plate, and some are equipped with rollers on the chain plate, etc., which are modified for application in different applications. In the same kind of products, according to the basic structure of the chain, that is, according to the shape of the components, the parts and parts meshed with the chain, the size ratio between the parts, etc., the chain product series is divided.

After the chain is cleaned and refueled, slowly invert the chainring, and the links that come out of the rear derailleur should be able to be straightened, if there is a chain link that still maintains a certain angle, it means that it does not move smoothly, it is a dead knot, and it should be adjusted. If you find a damaged link, you must replace it promptly, and it is recommended to maintain Shimano's chain by strictly separating the three types of pins and using connecting pins.

Pay attention to the level of the chain beater, so that it is not easy to crook the thimble. Tools are used carefully, which can not only protect the tools, but also achieve good results, otherwise the tools are easy to be damaged, and the damaged tools are more likely to damage the parts, which is a vicious circle.
