Park Tool - LRT-4 Shimano Direct Mount Lockring Tool

Park Tool LRT-4 Lockring Tool, Shimano Direct Mount

Removes and installs the lockring on Shimano direct mount chainrings, like XTR 9120, XT 8120, MT900 and other Shimano direct mount cranks. Fits lockrings with a 41mm outside diameter and 16 notches. CNC machined from 6061 aluminium with a flat face for good engagement and less chance of marking the crank.

It has a 36mm hex, so to torque it properly you'll want the TWB-36 crow foot and a 3/8" torque wrench. The TWB-36 is listed here as a separate option. Not sure it fits your bike? Talk to us and we'll check.
