Here, I will tell you how to find and identify the master link on a bike chain and how you can easily open and close it. So read till the end.
Find Master Link Following A Few Methods

There are multiple ways to identify the master link. Here are a few methods for finding it easily –
Study Basic Info about Bike Chain
First, you need to know the basics about your bike chain. Every bike chain comprises a series of metal plates or links. These links are held together by pins. The distance between these pins is what dictates the width of the chain.
The master link allows you to remove the chain without disassembling it. This link is also sometimes called the connecting link. Master links come in two parts (outer and inner plate) connected by a pin or rivet and can be found at any hardware store.
Find Master Link by Measure
Measuring the width of your chain is the most accurate way to find the master link. To do this, you’ll need a caliper or a ruler that can measure in millimeters. Start by counting the number of links in your chain.
Then, use the caliper to measure the width of 12 links. This will give you the pitch of your chain, usually between 1/8″ and 3/32″.
Find It by Looking
If you don’t know the measurement of your bike chain, then another way to find out is by looking at it. First, take a close look at the chain and try to find a link that looks different from the others. For example, the master link will usually be a different color than the rest of the links, or it may have a different finish.
Search with Finger
Another way to identify the master link is by feeling it with your fingers. Run your fingers along the length of the chain until you find a link that feels slightly loose. This is likely the master link.
Now that you have found the master link, the next step is to open or close it.
How to Open Or Close The Master Link Once It Is Found

If you need to remove the chain entirely, you will have to open the master link. To do this, collect a chain tool and try our following tips.
How to Open The Master Link

- First, you will need a chain tool.
- Next, align the chain tool over one of the pins on either side of the master link.
- Then push until the pin comes out.
- After that, you can slide the master link off of the chain.
How to Close The Master Link
- To close the master link, start by putting the inner plate of the master link into place.
- Then use the chain tool to push one of the pins back.
- Finally, snap the outer plate into place.
These simple steps can help you quickly repair and clean the bike chain. Keeping it clean will ensure the optimal performance of your ride.
