Unior Cassette Lockring Tool with Guide PinIf you'd rather use our ratchet or adjustable wrench when you're working with your Shimano or SRAM style cassette, or if you'd just like something a little more compact, we've got you covered. This cassette removal tool is made with a guide pin that helps keep the tool from slipping out of the lock ring under heavy torque. Simply remove your quick release and install the lock ring tool. Does not fit Campagnolo.
