Made from heat treated alloy tool steel, this tool works with all Shimano freewheels since 1985, Uniglide before 1985, SIS, and Sachs Aris freewheels. Thin wall construction means you won't need to remove your cones or axle nuts.
Notes: Not intended for use with Falcon brand freewheels (FR-7). For Shimano cassette lockrings use the FR-5.
