This makes for a very simple method of removing cassette lockrings when used with a Stein HyperHandle. These are available for standard 5mm QR skewer hubs or 12mm oversize axles. How to use Instructions Install driver on your favorite 3/8″ drive ratchet or torque wrench. Locate driver through HyperHandle tool with the correct pins facing the cassette.
