If your chain does not have a master link, you’ ll have to use a chain tool to break the chain. Open the master link, slide it off, and put it someplace where it won’t get lost. Some master links are also disposable, and can only be removed by bending them apart with needle-nose pliers or a specialized tool.
Replacement Pin or Master Link: New chains will come with either a new pin, or a specialized link called a master link, to connect the two ends of the chain together.
In order to shorten the link without a chain tool, you need an alternative tool like a hammer, pliers or thin nail. They will assist you in pushing the pin easily. You can position the chain over a socket, and hit it with a hammer. Then, you can now pass the bolt all throughout the open holes.
How often should I change my bike chain?
The 2,000-Mile Rule. To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles.

How do I know my bike chain size?

A master link is just as strong as any other link on the chain. There’s no reason you can’t use a couple of them.
