FR-5.2H Cassette Lockring Tool

Park Tool FR-5.2H Cassette Lockring Tool

The FR-5.2H Cassette Lockring Tool from Park Tool fits most Shimano fitment cassettes even without removing the quick-release skewer. The tool is also handy for some Shimano style disc brake lockrings and features a removable handle so that the tool itself can be replaced separately if it becomes worn or damaged.
