Park Tool Casette Lockring Tool FR-5.2H

The FR-5.2H is a dependable, professional-grade tool for removing and installing cassette lockrings. It features a long, robust handle and a large passthrough hole, allowing it to be used without the need to remove most quick-release skewer nuts. The FR-5.2 is compatible with the most common tool fittings found on 7-to-12 speed cassette lockrings, including those from Shimano, SRAM, and other brands. It also fits disc brake lockrings, lockring adapters with 12 internal splines, and the top caps of certain Rock Shox suspension fork models.
