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.

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.

My bike came with center lock brake rotors and one of them was loose. I bought this because I would need it to service my bikes brakes and it works just like it is supposed to.

You get what you pay for. This is a genuine Park Tool item and works as well as expected. Fits snug into the cassette for sturdy and easy removal.

It is beautiful thing when you use the right tool, it works like a champ, and it comes at a great price. I used this on my Wahoo Kickr Core to install a Shimano cassette.

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!

I stripped the end millimetre of the knurls off my old FR-5 Park Tool tool. It predates thru axles by 20 years and consequently unless the axle is removed there is only a small section of the tool that engages with the splines in the cassette. I had removed, replaced and tightened the 11 speed Shimano cassette without realising that I'd omitted to include one of the spacers. This meant the tool had even less to engage on, and what little there was stripped as I tried to remove the cassette.The new one arrived quickly and it is purpose built for the job. The removable blue centre guide (It is secured by a small hex bolt) fits perfectly into the thru-axle and the tool engages fully with the cassette's splines; thus the task of loosening and tightening the cassette is easy to do.A modest price to pay for such an essential maintenance tool.

I hadn’t used the tool at the time of writing this review, however, as is typical of Park Tool, it is of high quality and will no doubt work well for a long time.
