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.
What type of cassette do I have?
To determine if a sprocket is a freewheel or cassette system, remove the rear wheel from the bike. Find the tool fitting on the sprocket set. Spin the sprockets backwards. If the fittings spin with the cogs, it is a cassette system with a freehub.
When should I change my bike cassette?
My rule of thumb is to replace it at 75 per cent wear (as measured with a chain-wear indicator). If you stick with this guideline, your cassette and chainrings will last a lot longer. A cassette, in most cases, can last for approximately two to three chain replacements if they are done at the right time.
How do you remove an old style freewheel?
- Mount bike in repair stand and remove rear wheel from bike.
- Remove quick-release skewer.
- Inspect freewheel center and select correct removal tool (see chart above).
- Engage tool into splines/notches.
- Reinstall quick-release skewer with skewer nut on outside of remover.
- Snug skewer nut against remover.
