    Tool to remove rear sprocket lock ring?

    Anyone know what tool I need to remove the rear sprocket lock ring on my GT Peace?
    This bike has a single speed cassette, not a screw on freewheel.
    Thanks

    Park HCW-5 hook spanner

    Or a pair of channel lock pliers, but those will make a mess out of the lockring if you're not careful, and maybe even if you are.

    Also, a chain whip

    1. Hook spanner- these are also available at stores like Harbor Freight Tools.

    2. Channel Lock

    3. Pipe wrench.

    You will also need a chain whip to hold the freehub while you loosen the locknut.

    Get the proper tools for the job. If you're like me, you'll use them often enough to justify it.

    Note that they don't have to be "Park Tool" branded.

    Thanks guys.
    Hook spanner it is then.
    Just out of interest, is the single speed cassette lockring the same as a BMX or fixed gear lockring?

    PS Steveob, the link you posted is for a regular Shimano geared type cassette lockring which fits inside the cassette body, mine fits outside the cassette body.

    I managed to find an old motorbike C spanner (for suspension adjustment), a little bit of filing made it a perfect fit for my lockring, and job done!
