There are alot of bikes out on the roads and trails that use older style Freewheel cassettes. These are a bit different because you don’t use a chain whip to remove them off the wheel.
Basically you take your cassette removal tool, place it in a vice.
Remove the axle nuts off the wheel. Place your wheel onto the removal tool that you placed in the vice.
Then turn HARD counter clock wise. Once you bust the grip, keep spinning the wheel until the freewheel comes off.
