stupid question but sprocket removal

[jonbott]

Use a chain whip to hold the casette still and remove the lockring with the appropriate tool (different for shimano or campagnolo).

Not really much difference in essence.

In order to remove a cassette, you have to have a chainwhip to hold back the cassette from freewheeling as you unscrew the lockring.

The lockring needs the correct tool to be inserted and a suitable spanner to shift it. The good thing is that the lockring won't be anywhere near as tight as a freewheel.

After undoing the lockring, the sprockets and spacers will slide off the freehub boss.

Easy done with the correct tools.

Gee, I need a vice, a monkeywrench and Plusgas to undo mine..

If it's a shimano cassette then the same tool that removes current shimano freewheels also fits the cassette lockring.

If it's that tight you must have done it up too tight when you put it on

Parktool, useful pics and clear instructions but it's all been said above already.

Are you sure? I have a Shimano cassette removal tool which I have used on my 8-speed MTB, but had to buy a different tool to remove the 7-speed freewheel on my wife's aprox 4 years old Revolution trekking bike, the spline pattern was different.

Compare Park cassette tool:
With Park freewheel tool:

Provided the no of splines are the same then no problem. The 2 photos you posted looks like the only diffence is the length of the splines. The number look identical. The freewheel removal tool does stick out as it bottoms out on the freehub but as the cassette lockring is generally not too tight this isnt a problem. I use the simano freewhell remover just like the park tool one shown in your photo to remove my cassette lockring.

There is the same number of splines in the same position. The difference is in the height of each spline. On the cassette tool they are 1mm high; on the freewheel tool they are 0.5mm high. As a result you can use a freewheel tool on a cassette lockring, but not a cassette lockring tool on a freewheel.

That explains it, I could not be bothered to count splines
