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.
Do all bike chains have a master link? Nope, not all chains have master links. If your bicycle has derailleurs, it means it’s unlikely that your bike’s chain will have a master link.
Count each outside link, which is easily identifiable by the large plates on either side of the link. Continue counting until you reach the beginning. Multiply the count by two to include the inner links. As an example, if you counted 55 outer links, you will know there are 110 total links.
A new bicycle chain usually comes with 116 links. This is long enough for the biggest chainrings and for most distances of rear wheel from front chainrings. So for optimal length a new chain is usually shortened from the 116 links that come in the box.
How do I know my bike chain size?
Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.
Why does bike chain jump?
Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.
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. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same. 4
