Pedro’s Pro HG Cassette Lockring Socket

The Pedro’s Pro Cassette Lockring Socket is a professional bicycle lockring tool designed for HG standard cassette lockrings, disc brake lockrings, and similar fittings with 12 splines and a 23.5mm outside diameter. It fits Shimano, SRAM, SunRace, SunTour, Chris King, and other compatible HG-style lockrings.

Both versions are made from alloy tool steel and fully machined to precise tolerances for a professional-level fit. Extra-long splines provide secure lockring engagement, while quick-spin knurling makes the tool easier to handle during setup and removal. The socket includes a 3/8 inch square drive for use with torque wrenches and a 24mm external drive for additional tool compatibility.

Choose the Standard version for general HG lockring service, or choose the With Pin version for added retention using the 5mm pin and removable magnetic 12mm pin design.
