What is the use of a chain puller for a bike?

It's useless, it's cheating money, it's superfluous, it's not as strong as two legs,

Summary. The bicycle chain puller is one of the most important components of the bicycle. If the chain puller is deformed, it may make it difficult to ride the bicycle or even make the bicycle unable to run.

Generally speaking, the causes of deformation of the chain puller include being used for too long, being hit or dropped, or being used in a harsh environment. If the chain puller is found to be deformed, it should be replaced or repaired in time to ensure the safety of riding and the service life of the bike.

Can you tell us more about that?

A chain cutter is a tool used to cut or attach a chain. There are two kinds of chain cutters: universal and special, the universal is that the speed chain can be detached, and the special one can only be dismantled by one speed.

Method of disassembling the chain using a chain cutter:

Tools: Chain cutter, double jump.

1. If the chain has been installed once before, then you should be careful not to hit the installed pin when cutting the chain again, if you hit the pin that was installed last time, and then drive the new pin into the link is not tight, and the chain will be damaged in serious cases. As shown in the figure below, the middle pin was driven last time, and if it is dismantled again this time, it will be somewhere else.

2. When using the universal chain cutter, you must not forget to adjust the "spacing adjustment nut", and you will find that there is a gap when you put the chain on the chain cutter.

3. At this time, the spacing nut should be adjusted so that it is close to the side of the chain, and the top of the chain cutter should be aimed at the pin of the chain, and the pin can be ejected by rotating hard, and the chain will be removed.

It is a tool to disassemble the chain. When changing or washing the chain, you need to cut the chain before removing it.

The chain speed is just thinner, the chain cutter is universal, but the high-end chain cutter is accurate, meeting the needs of 10-speed and 11-speed chain disassembly, and those pins are more fragile.

In addition, the 10-speed and 11-speed chains have fixed disassembly pins or directly use Velcro buckles, and there is almost no need for chain cutters.

By changing gears, you can maintain the strength of your pedals, maintain your cadence, and save your physical strength. There are also some difficult movements that can be completed (there is a certain danger, such as continuous stairs).

There is no problem in riding on the road without a transmission, and you can only get off and push when you encounter a high slope.

The transmission does not need to be uphill and tired, and it is not convenient to ride.
