Knowing how to size a bike chain is important for any cyclist. A bike chain that is too short will not be able to reach the rear derailleur, while a chain that is too long will be prone to derailment. The correct chain length will ensure that your bike shifts smoothly and efficiently.
There are a few different ways to size a bike chain. One way is to use a chain checker tool. This tool measures the length of the chain and will tell you if it is too short, too long, or just right. Another way to size a bike chain is to wrap it around the chainrings and rear cogs. The chain should be long enough to wrap around the largest chainring and the largest cog without being too tight.
