Your Bottom Bracket is Making Noise

Manufacture Failure

As with any other part of your bike, it’s important to keep your bottom bracket clean and well-lubricated. Bearings can wear prematurely from dirt and grime buildup over time.

Hard riding conditions

If you ride your bike in extreme conditions, such as in mud or water, it’s more likely that your bottom bracket will fail sooner than if you rode in more moderate conditions. The reason is that moisture can cause corrosion and rust, which can lead to bearing damage.

Crashes

It Was Poorly Installed

If your bottom bracket is not installed properly, it’s more likely to fail. This is usually not an issue if you have your bike serviced by a qualified mechanic, but if you try to install it yourself, it’s important to be very careful and follow the instructions carefully.
