How can I remove my cassette? I've been planning to replace them for a while now but can't really remove them, no matter what I do.

Im using a SHIMANO FH-TY500 hub, paired with a SHIMANO TOURNEY 7-Speed MTB Cassette Sprocket.

You have a freewheel, not a cassette, you need to remove it using a freewheel tool by unscrewing it. Unlike with a cassette, you do not need a chain whip.

  • But it looks like the SHIMANO FH-TY500 hub has a freehub? It’s strange because the thing in OP’s photo doesn’t look like the freehub cassette lockrings I’m used to but it certainly looks like it has the internal “teeth” for a cassette lockring tool.

  • Indeed, it really does not look like lockrings I am used to, but I stand corrected. Apr 2 at 12:38

    Image definitely looks like a freewheel to me - this answer seems correct. But googling OP's model number returns bike.shimano.com/en-EU/product/component/shimano/… which is a freehub. I suspect they've misread the model number, or its a really old part with a similar model number.

    @Criggie Thank you for the heads up. I will undelete this answer because it really looks like a freewheel. Apr 2 at 19:22

    100% a freewheel in the picture. I suspect they're looking at published specs on a bike that's had its wheel replaced. Apr 3 at 7:12

The SHIMANO FH-TY500 hub is a freehub design (not the older freewheel where the ratcheting mechanism is built into the cassette).

You’ll need:

  • a cassette lockring tool (e.g. Shimano TL-LR10) and a spanner or ratchet to turn it.

  • a chain whip (you might get away with a bench vise and an old chain)

You’ll need quite some force/torque to remove the lockring. Put the chain whip on the second largest sprocket and apply as much force on the spanner/ratchet as you can. The lockring has a normal right-handed thread (i.e. loosens when turned counter-clockwise).
