What tools do I need to remove a bike cassette?

The lockring is designed to hold the cogs of the cassette in place on the hub. In order to remove and replace your cassette, you need to unscrew this lockring. You’ll need three tools to do this: a chain whip, a cassette lockring remover and a large adjustable crescent wrench.

When should you replace rear cassette?

Once the chain wear is approaching 1% “stretch”, it’s usually time to replace the cassette as well. Because the teeth on the cassette will have worn down to more or less match the chain wear, if a new chain is fitted to a worn cassette, it won’t mesh properly and may jump or skip, especially when changing gear.

What can I use if I don’t have a chain whip?

If you have a regular claw hammer and another length of chain, then you can create your own chain whip. Just drape the length of chain through the claw part of the hammer with the majority of chain going away from the handle of the hammer.
