TL-LR021 Lock Ring Tool

The Shimano TL-LR021 (also known as TL-LR21) is a specialized lockring tool designed specifically for Shimano’s high-end 12-speed XTR M9200 cassettes that feature a 9–45T range and a 9-tooth smallest cog. These cassettes use a unique Micro Spline lockring that requires a dedicated tool for safe installation and removal. 

Constructed from hardened steel, the TL-LR021 provides a precise, slip-free interface that protects both the lockring and cassette during service. It’s an essential tool for professional mechanics and home users working with Shimano’s latest XTR drivetrain technology.
