RISK RL345/RL346 Bicycle Centerlock Lockring & Bottom Bracket Removal Tool

The RISK RL345/RL346 removal tool system is designed for removing and installing bicycle external lockrings, centerlock disc rotor lockrings, and compatible bottom bracket cups. It is suitable for 44 mm outer diameter, 16-notch lockrings, commonly used on selected centerlock rotor lockrings and bottom bracket systems.

The RL345 removal socket tool is made with a metal body and is designed for secure engagement with 44-16T lockrings. It is compatible with BB52, RS500, GXP and other similar bottom brackets, as well as Skypivot® power meter lockrings.

The RL346 protective pad set is used with the RL345 tool to help protect lockrings during installation or removal. The tool features a replaceable protective pad design for easier maintenance and reduced surface damage.

The RL327 quick-release anti-slip device is available separately and is recommended when removing lockrings. It helps keep the tool aligned and reduces the risk of slipping during high-torque operation.
