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

Park Tool offers a full range of tools for bicycle cassette lockring removal and installation. The FR-5.2 fits 12 spline 23.4mm diameter tool fittings - the most common tool fitting found on 7-12 speed bicycle cassette lockrings, including models made by Shimano, SRAM, SunRace, SunTour, Chris King and others. Also fits Shimano disc brake lockrings with 12 internal splines, and top caps of some Rock Shox suspension fork models including Pike, Lyrik, SID, Revelation, Reba, and Paragon. Thin wall construction allows use without removal of cones and locknuts. The 1" hexagonal base can be used in conjunction with a socket, wrench, or bench vise. Heat treated alloy tool steel construction for a lifetime of use.

The FR-5.2 has 12 splines that are approximately 23.4mm across at the widest point. Center bore for axle clearance is 12mm.

PARK TOOL: YOUR GUIDE TO THE WORLD OF CASSETTES & FREEWHEELS

CASSETTE OR FREEWHEEL?

To determine the type of rear sprocket system you have, find the tool fitting on the sprocket set. Spin the sprockets backwards. If the fitting spins with the cogs, it is a cassette system. If the tool fitting does not spin with the cogs, it is a freewheel system.

CAMPAGNOLO OR NO?

If you have a multi-speed cassette, you need one of two tools. If the cassette, derailleur, or shifter are labeled with Campagnolo, the tool for you is the BBT-5/FR-11. Otherwise, you will require a tool in our FR-5.2 line.

THE RIGHT TOOLS FOR THE JOB

In addition to the correct tool, you will also need a method of driving it (such as an adjustable wrench or 1" socket) as well as a chain whip to hold the cassette in place as you remove the lockring. Park Tool makes a full line of chain whips and wrenches for this very purpose.

Park Tool makes a full line of cassette lockring and freewheel tools to empower you to remove the rear cogs of virtually any bicycle. Here's a selection of tools similar to the FR-5.2GT:
