  • why won't my cassette come off?

    Just basic Shimano stuff on the commuter hybrid – got the lockring tool but it won’t spin, with or without a chainwhip. Do I just give it what for with the lockring tool being monstered by the longest adjustable I can find? Why won’t it spin??

    Feeling like a div, and for once hoping it’s an accurate feeling.

    WD40/gt85 and leave it for a few hours and try again?

    You’ll need the chainwhip to get it off. It’s a normal thread, so undoes anti-clockwise.

    They can be very tight and undo with a ggrrrr.
    I use a massive adjustable on my lockring tool & put the chainwhip around quite a large sprocket.

    Are you turning it the right way? The lockring will never come undone without a chainwhip as the cassette will just spin.

    If you have a vice then put the lockring tool into the vice facing upwards. Drop the wheel down onto it and use the wheel as a lever.

    Put a metal pipe over the end of the spanner and give it some welly.

    And use QR skewer to hold the lockring tool on

    That’s the thing – it doesn’t spin either way you apply pressure to the lockring, so chainwhip or no, makes no difference.

    It’s not a freewheel rather than a cassette is it?

    Sounds to me by turning it ‘against’ the cassette you’ve over tightened it. It’ll now be a bugger to get off with a whip. What are you using as the handle for leverage on the removal tool? You may have to extend it for better leverage. Oh and get someone to hold the whip or you’ll do yourself a mischief

    Freewheel?

    Well – the freewheel still freewheels, if you turn the cassette one way, but my expectation was that with tje lockring extraction tool inserted, I would be able to turn that one way (with the cassette, hence the need for a chainwhip) but not the other. I don’t need the chainwhip to hold the cassette as it ain’t spinning in either direction. Shimano 7 speed, freewheel noisy and has maybe a mil of movement between cassette and tje wheel, not sure where the movement is and have gone to bed in a huff so not checking tonight.

    so the freewheel won’t turn either way when you have the cassette tool engaged ?

    weird – is it one with a “prong” that fits down the QR axle and if so, was it stiff to push in ?

    Sounds like being 7spd it’s very likely a freewheel not a cassette. You don’t use a chain whip on a freewheel and they can be very tight, it tightens the way you pedal.

    Put the freewheel tool in a vice and turn the wheel, give you loads more leverage safely.

    Double check you know the difference between a cassette and a freewheel
