The cassette on a bike is used to provide an efficient ratio between pedaling speed and overall speed by changing gears.

How Do I Know If My Bike Cassette Is Worn Out?

There are many ways to tell if your cassette needs replacing. Here are a few:

  1. When you start feeling resistance when you’re riding, this is one of the first signs that your cassette needs replacing. Another sign is when your chain starts slipping off of the gears, especially if you’re doing more than 20mph.
  2. If your bike has a lot of noise when riding, it might be time for a new cassette.
  3. If the bike feels like it’s slipping or not as smooth as it used to be, then it might be time for a new cassette.
  4. If you start having problems with gears when rolling on hills, then it might be time for a new cassette.

The following are some factors that can affect the life span of your bike cassette:
