How to Choose a Freewheel or Cassette?

Freewheel and cassette: two very different items that are both essential to your drivetrain.

Your choice of cassette or freewheel will depend on two criteria: your usage and the number of cogs.

1. Usage

To make the right choice, you need to know the difference between a freewheel and a cassette.

On a cassette, the cogs slot one by one onto the cassette body. They are then held in place with a nut.

The freewheel is a block of cogs that screws directly onto the wheel.

2. The Number of Cogs

If your bike has a 7-speed freewheel, you must replace it with a 7-speed freewheel.

A cassette has 7 to 11 cogs.

A freewheel can only be replaced by a freewheel.

Remember to grease your drivetrain regularly to keep everything running smoothly.

You should change your chain each time you change the cassette: if you use new cogs with a worn chain, it will jump and won't hook on properly.

The opposite (changing the cassette when you change the chain) depends on how worn it is. The best approach is to always change both of them at the same time
