Cassette Locking Tool for FR-5.2

Park Tool Cassette/Disc Brake Lockring Tool: The FR-5.2 for Convenient Bicycle Maintenance

Park Tool, a trusted name in the bicycle industry since 1963, offers a comprehensive range of tools to facilitate the removal and installation of bicycle cassette lockrings. The FR-5.2 tool, part of this extensive lineup, is designed to cater to the most common tool fittings found on 7-12 speed bicycle cassette lockrings.

The FR-5.2 tool features a 12 spline, 23.4mm diameter design that is compatible with cassette lockrings from leading brands such as Shimano, SRAM, SunRace, SunTour, and Chris King, among others. Additionally, it fits Shimano disc brake lockrings with 12 internal splines, as well as the top caps of select Rock Shox suspension fork models, including Pike, Lyrik, SID, Revelation, Reba, and Paragon.

The tool's thin wall construction allows for use without the need to remove cones and locknuts, making it a convenient choice for bicycle maintenance. The 1" hexagonal base can be used in conjunction with a socket, wrench, or bench vise, providing versatility in its application.

Crafted from heat-treated alloy tool steel, the FR-5.2 is built to withstand the rigors of frequent use, ensuring a lifetime of dependable service. Whether you're working on a cassette, disc brake, or suspension fork, this tool is designed to empower mechanics and riders of all skill levels to service their bicycles effectively.

To determine the type of rear sprocket system on your bicycle, simply spin the sprockets backwards. If the tool fitting spins with the cogs, it is a cassette system; if the fitting does not spin, it is a freewheel system. For Campagnolo-equipped bicycles, the BBT-5/FR-11 tool is the recommended choice, while the FR-5.2 line caters to non-Campagnolo setups.

In addition to the FR-5.2, Park Tool offers a variety of similar tools to meet the diverse needs of bicycle maintenance, including the FR-5.2G with a 5mm guide pin, the FR-5.2GT with a 12mm guide pin, the FR-5.2H with a built-in handle, and the FR-1.3 freewheel remover.

Trusted by mechanics and enthusiasts alike, Park Tool's commitment to quality and innovation has made them a reliable partner in the world of bicycle care and maintenance. The FR-5.2 Cassette/Disc Brake Lockring Tool is a testament to this legacy, empowering cyclists to confidently service their bicycles and keep them running smoothly.
