Are you sure its a cassette and not a freewheel?

yep, I turned to Sheldon to determine that first..

Tony, I tried your squeeze technique with the wrench+chain whip. It
felt like I was getting more leverage, you're right, but still no
movement.

No vice at my disposal at the moment.. Is sudden force (ie a hit with a
lump hammer on the wrench) a really bad idea?


No, try the lump hammer. Its best though if you can put the whip and
wrench in the above squeeze position with the handle of one resting on a
hard surface (top of a wall or such like) and then hit the other handle.
Usually its getting the first budge out of it that's difficult. Once
that has happened it tends to undo easily.

Try holding the removal tool in the vice and turning the whole wheel

me.

That works with freewheels, but not with cassette hubs.

As an alternative, if you can lay hands on a piece of tube which will fit
over the end of the wrench...

In the days of obstinate freewheels with big sprockets, I used a 10"
adjustable spanner with a Bickerton seat tube artfully flattened at one end
to extend the total length to about two of the BRITONS' feet. Back then a
source of Bits of Borken Bickerton was readily available in the form of Lt.
Col. Larrington (retd.), who would break Bickies with monotonous regularity
until such time as they started flogging rebadged Dahons instead.

Putting just the right amount of gin in your goldfish bowl makes
the fishies' eyes bulge and causes them to swim in a very
amusing manner.

Nothing like a tandem to weld the freewheel to the sprockets. Sometimes
needed a gert big vice and two gert big folk tugging on the wheel to
break it free.

On a tour once two cogs made a gentle tinkling sound as the remnants hit
the tarmac. Had to disassemble the freewheel, with hammer & chisel,
courtesy of a friendly NLBS, grip the body in a vice and grunt like hell
to break it off. Colleague was on standby to DHL a complete new tandem
wheel from the UK had we failed.

Indeed. I read somewhere that the old Sun Tour Alpine 14-38 freewheels were
fit and forget in tandem use, coz once it'd done a few steep hills, no tool
made of Man was ever going to get it off again.

I'm not sure I'd fancy that...

They came for Dani Behr; I said: "she's over there, behind the

If you are goung along the percussive persuasion route, you might want
to try giving the lockring a sharp tap along it's axis with a small
hammer.

If all else fails I use a small pair of stilsons (18"). If I am at my
dad's then I can borrow the medium sized ones (30" or 36"). His
definition of large is 'as tall as him' (5'4").

Quoting Tony Raven :

One of that was enough to convince me to put a cassette hub on.

Thanks to all who replied.

To end this debacle, after hitting, groaning and trying all the tools
at my disposal, I took it down the LBS.

They just put the wheel in a vice, had both tools with considerably
longer handles than mine, and crunch. All done.

Maybe I'm just weak.

I doubt that your weak, these things just happen. I remember a friend who
had a seized pedal on a crank; we tried everything with no success. In the
end we used an extension bar on an adjustable spanner, which finally
released it. She now religiously keeps the pedal threads greased.
