SR-12.2 12-Speed Compatible Chain Whip/Sprocket Remover
We don´t know of any other way to remove a cassette lockring without stabilizing the cassette, and sooner or later you´ll want to remove it for cleaning or swapping out the gearing for something more appropriate on the day. If you don´t own one yet and are in the market for a great chain whip for your home shop or toolbox, consider the 12-Speed Compatible Chain Whip/Sprocket Remover - SR-12 from Park Tool. You´ll find yourself using it more than you´d think and with its heat treated construction that prevents bending and flexing, it´ll last for years.
The Park Tool SR-12 Chainwhip works on 5 through 12 road and mountain cog cassettes and freewheels regardless if your alliances lie with SRAM, Shimano, or Campy. At the bottom of the tool, it features a 1in box-end wrench that fits Park Tool freewheel and cassette lockring tools so you can reinstall your gear clusters. A comfortable molded handle adds grip while the hardened pins add durability and keep the chain securely in place.
