You’ll need a cassette tool, a whip, and a wrench.

First, remove the quick release, as it’ll get in the way. Make sure you don’t lose the little springs, even though they don’t really do anything.

Here, we can see the cassette tool fits right into the lock ring at the end, but if we try to unscrew it the cassette just turns freely. This is what we need the whip for, but you could also use a spare piece of bike chain and some pliers or a bench vice.

Give it a good crank and it should come loose. On many cassettes there will be a few loose gears at the end, so make sure you keep these together.

When you install the cassette on the new wheel, notice that the spline isn’t the same all the way around. This part right here has a smaller ridge on it, so you’ll need to line up the cassette for it to slide on. When you find the right spot it should go on with very little effort.

Screw the lock ring back on with your fingers, and then give it a good crank with the wrench. You don’t need to make it crazy tight, but be firm.

Put your quick release skewer back on, and you’re all set. Check the description for links to all the tools, and thanks for watching. I’ll see you next time, and ride safe.
