Heat-treated steel alloy construction means the tool handles the torque required to break loose stubborn lockrings without rounding out or flexing under load. Thin-walled design lets you work without pulling cones and locknuts first, which matters when you're mid-service and don't want to rebuild a hub to change a cassette.\u003c\/p\u003e\n\n\u003cp\u003eCompatibility is broad. The FR-5.2 works with 7- through 12-speed cassettes using the standard spline interface, and the 12 internal splines also fit disc brake lockrings and adaptors — so one tool handles both drivetrain and brake rotor work on compatible wheels. The hexagonal base accepts a wrench, socket, or vise, giving you options depending on whether the wheel is in a stand or you're working with it clamped down.\u003c\/p\u003e\n\n\u003ch3\u003ePark Tool Cassette Lockring Tool Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e 7- to 12-speed cassettes with standard spline interface\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAlso fits:\u003c\/strong\u003e Disc brake lockrings and adaptors with 12 internal splines\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Heat-treated steel alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive interface:\u003c\/strong\u003e Hexagonal base — works with wrench, socket, or vise\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Thin-walled for use without removing cones and locknuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Park Tool","offers":[{"title":"Default Title","offer_id":43711407587372,"sku":"FR-5.2","price":10.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/park-tool-cassette-lockring-tool-fr-52-1046448.jpg?v=1771295349","url":"https:\/\/ricycles.com\/products\/park-tool-cassette-lockring-tool-fr-5-2","provider":"RA Cycles","version":"1.0","type":"link"}
