Park Tool Cassette Lockring Tool with Handle

Park Tool's FR-5H is a fast and convenient tool to remove and install 12-spline Shimano/SRAM-style cassette lockrings, as well as similar lockrings on rotor discs. The FR-5H features a modified FR-5 tool that allows use without removing most quick release skewer nuts. The removable, threaded steel handle makes it possible to replace a worn or damaged head.
