## Description

Product description Park Tool FR-5.2GT Bicycle Cassette/Disc Brake Lockring Tool with 12mm Guide Park Tool offers a full range of tools for bicycle cassette lockring removal and installation. The FR-5.2GT fits 12 spline 23.4mm diameter tool fittings - the most common tool fitting found on 7-12 speed bicycle cassette lockrings, including many models made by Shimano , SRAM , SunRace , SunTour , Chris King and others. Also fits Shimano disc brake lockrings with 12 internal splines. Thin wall construction allows use without removal of cones and locknuts. Features a 12mm guide pin to stabilize the tool when used with thru-axle hubs. 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-5.2GT has 12 splines that are approximately 23.4mm across at the widest point. 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 TRUSTED SINCE 1963 Since our origins in the back of a bike shop in 1963, it has been Park Tool's sole mission to design and manufacture high-quality tools that empower mechanics and riders of all skill levels to service their bicycles. Just like our other 500+ tools, our cassette and freewheel tools are a product of our decades of experience and expertise in the industry, in the shop and on the trail.

## Questions & Answers

**Q: Can the 12mm pin be removed?**
A: NO, I bought this on 1/10/2022 and the pin cannot be removed.  It shows a hex nut in the picture, but mine is riveted on with no way to remove the center pin.

**Q: What size is the nut?**
A: It fits into a 25.4mm or 1" wrench.

**Q: Is the internal cavity deep enough to go over the left 12 mm axle spacer to allow removal of the center lock brake disc nut?  Needs to be about 15 mm.**
A: No Problem. You should have a few mm to spare.

**Q: Do I need to buy this instead of old/regular 5.2 which works with 5mm skewer wheels?  It's not like the cassette is not centered threading the ring on**
A: No, the FR-5.2 would work or the FR-5.2G with the guide pin also works very well.

High quality lockring tool with 12 mm guide pin for proper fit on thru axle hubs. Worked great for removal and installation of my Shimano cassette and will surly work with other brands as well. Pair it up with a 1” socket or wrench for great stability and ease of use. From my experience, ParkTool always provides exceptional value for the money!
