The Pedro's Cassette Lockring Tool is a must-have for your home shop or travel kit. It's constructed from heat-treated steel and made to professional quality standards, ensuring strength and long-lasting performance. The tool precisely fits HG standard cassette lockrings as well as Shimano disc brake lockrings, with a second option available for Campagnolo cassette lockrings. It works perfectly with Pedro's snap-channel Pro Socket Handle, but can be used with a 24mm socket or wrench, with a square 1/2in ratchet driver, or even in a bench vise.
