The LRT-1.2 is a purpose-built workshop tool for removing and refitting the lockring that secures the front chainring on DJI Avinox and Bosch Gen 2 e-bike motors. Once the driveside crank arm has been taken off, the tool locates on the 8 notches of the lockring so you can service the drive unit cleanly, without chewing up the ring or the motor. It is machined from heat-treated 4140 steel and plated for a long working life, and is a direct replacement for the Bosch 0275009003 service tool.
