Can't do it :evil: . I have a chain whip, correct removal tool and a big mutha of a spanner. I'm going anti clockwise with the spanner & clockwise with the chain whip.

Any suggestions welcome.

is it spinning or just not budging?

I think it was Sheldon brown that suggested put the tool in a vice and use the wheel to undo it rather than a spanner.

It's not spinning, or budging for that matter. The wheel and all it's components don't seem rusty at all so it's got me beat at the moment. I have a vice a work so I may try that.

I bought a second hand wheel and could not get the sprocket off it. I tried my chain whip, and a vice, it still would not budge.
Then I bought one of these:

Pedros make it, was designed by Leonard Zinn. An example of true genius, what an amazing world we live in.

That looks way cool. Is the point of it to apply as much force as possible and where did you get it from?

It locks onto the cassette so that you have a firm hold.

My commuter had a cassette that I could not remove, not sure why as I use a torque wrench to tighten to correct setting. Tried and tried and bent the chain whip so it was useless.

I bought the Pedros tool but have found its not long enough. For a really tight lockring you cant get enough leverage on it. I ended up putting a steel bar on the end of it and off came the cassette.

Its good, but could be better with a longer lever arm.

Would I buy again? Well I was not going to get the cassette of any other way, but for the price it could be better.

I use standard 1/2" square drive rear cassette removal socket.

Hook it up to a 30cm standard car breaker bar for the hard one. Never fail.
