Park Tool FR-5.2H Cassette Lockring Tool with Handle

Park Tool FR-5.2H Bicycle Cassette/Disc Brake Lockring Tool

The Park Tool FR-5.2H is a professional-grade tool designed for the removal and installation of bicycle cassette lockrings. Featuring a robust construction with a long, sturdy handle and a large passthru hole, it facilitates usage without requiring the removal of most quick-release skewer nuts. This tool is specifically crafted to fit 12 spline 23.4mm diameter fittings, which are the standard across 7-12 speed bicycle cassette lockrings from major brands like Shimano, SRAM, SunRace, SunTour, Chris King, and others.

In addition to cassette lockrings, the FR-5.2H also accommodates Shimano disc brake lockrings with 12 internal splines and serves as a tool for removing top caps on certain Rock Shox suspension fork models such as Pike, Lyrik, SID, Revelation, Reba, and Paragon. The 12 splines on the tool measure approximately 23.4mm at their widest point, and the center bore ensures compatibility with axle or quick-release nut clearances up to 20mm.

Determining Your Sprocket System: Cassette or Freewheel?

To identify whether your bicycle features a cassette or freewheel system, locate the tool fitting on the sprocket set and spin the sprockets backwards. If the tool fitting rotates with the cogs, it indicates a cassette system. Conversely, if the tool fitting remains stationary while the cogs turn, it signifies a freewheel system.

Campagnolo Compatibility

For bicycles equipped with multi-speed cassettes, the choice of tool depends on whether the components (cassette, derailleur, shifter) are branded Campagnolo. If they are, the appropriate tool is the BBT-5/FR-11. Otherwise, the FR-5.2 series tools, such as the FR-5.2H, are suitable for other brands.

Choosing the Right Tools

In addition to the correct lockring tool, you will need a means to drive it, such as an adjustable wrench or a 1" socket, along with a chain whip to secure the cassette during removal. Park Tool offers a comprehensive range of chain whips and wrenches designed specifically for this purpose. Their extensive line of cassette lockring and freewheel tools empowers cyclists to remove rear cogs from virtually any bicycle.
