The FR-5.2H is a reliable, professional option for cassette lockring 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 lockrings, including models made by Shimano®, SRAM®, and others. Also fits disc brake lockrings and lockring adapters with 12 internal splines, and top caps of some Rock Shox® suspension fork models.
