Because it helps convert the kinetic energy of pedaling into the movement of the wheels, the chain is an integral part of your bike. While it’s not as likely to get damaged as the tires, it’s still susceptible to wear over time. That wear can also be exacerbated by improper care and other common mistakes. Here are a few ways you might unknowingly damage your bike’s chain.

3 Common Causes of Bike Chain Damage

1. Lack of Cleaning

The rule of thumb is that you should clean your bike every 20 to 25 rides—or more often if you frequently ride in muddy conditions. Spray your bike down with water to remove any built-up dirt, and then clean the chain with a degreaser and an old toothbrush. Rinse again with water, and let the chain dry.

2. Improper Lube Use

Greasing your chain is a critical part of maintaining proper bike function and preventing premature wear. If you grease the chain too infrequently, it will chafe against the drivetrain components and wear out more quickly. Each time you clean your bike, apply the recommended amount of grease for your chain. However, don’t overdo it; too much grease will collect dirt and begin clogging the drivetrain.

3. Riding With a Dated Drivetrain

The chainring—the sprocket that your chain wraps around—is susceptible to wear as well. The teeth on the chainring can become rounded over time, creating the chance of slippage, which can cause you to lose control of the bike. On multispeed bikes, the group of chainrings is known as a cassette, and rounded chainring teeth can cause difficulty shifting gears. To maintain your chain, keep all of your drivetrain components in good condition.
