Birzman Cassettes and brake disc socket wrench (491-073-LOCKRINGRM12)

The cassette and disc brake socket wrench Ø12mm (Shimano® HG?) is a precise cassette and disc brake puller for professional bicycle maintenance. Equipped with an integrated Ø12-mm guide pin for thru-axle hubs, this tool ensures a completely stable and material-friendly fit when loosening and tightening.

The socket is universally compatible with Shimano® HG? and SRAM® cassettes, Shimano® Center Lock disc brakes, as well as all similarly designed lock rings with 12 teeth and an outer diameter of Ø23.4 mm.
