> 3 dayIve been using old Park cassette tool for QR axles and although it works, the tool was always getting cocked sideways in the lock ring since it was made for a quick release skewer. This tool works great for my 12mm thru axles and stays nice and square to the lock ring. One note, I always used a 24mm socket with my old tool but this new requires a 1 socket, the 24mm was too small.

> 3 dayThis tool did its job in installing a cassette on a bike wheel. The 12mm pin keeps it stable.

> 3 dayit works, but for the price I think they couldve figured out by now to make it more handy... like idk, not needing an onch socket or an awkward big ass crescent wrench. would be really nice if this could just be direct onto a socket wrench.

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 JOBIn 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. |
