Park Tool Cassette Lock Ring Tool (FR-5.2H)

Park Tool’s FR-5.2H is a reliable, professional option for cassette lock ring removal and installation, with a long sturdy handle and a large passthru hole that allows use without removing most quick-release skewer nuts. The FR-5.2 is designed to fit the most common tool fitting found on 7-to-12 speed cassette lock rings, including models made by Shimano, SRAM, and others. It is also compatible with disc brake lock rings and lock ring adapters with 12 internal splines, and top caps of some Rock Shox suspension fork models.
