Birzman Cassette socket wrench

The Lockring Socket (Shimano® MF? & Campagnolo®) is a versatile removal socket for professional bicycle maintenance. This tool is universally compatible with Shimano® MF? screw-on cassettes as well as similar 12-tooth freewheels with an outer diameter of 22.7 mm. Additionally, it fits perfectly for Campagnolo® cassette lockrings, bottom brackets, and Center Lock brake discs (rotors).

Thanks to the standardized 1/2" square drive, the tool can be ideally operated with a ratchet or torque wrench – such as the dual-release Birzman Torque Wrench 10-60Nm, to tighten the lockrings precisely according to manufacturer specifications.

Made from robust alloy steel, this socket offers a precise fit, excellent power transmission, and maximum durability for daily workshop use.
