rear cassette lock tool.. for SRAM
Good quality and fit for purpose. Used to remove my old sram cassette and install new sram cassette. Seems expensive for what it is, but only need to buy it once and this ones certainly solid, should last forever. Worth the money given that some other types of these locks appear to be either a bit less robust, and believe me it did take some welly to get old lock ring off!, or more expensive. NB some have guide pins, not really necessary as you can screw the bikes quick release spindle nut down above this one to keep it square while using the spanner.
