OneUp Cassette Lockring Tool

A heat-treated steel, twelve-spline lockring tool with a hollow centre. Use a 1/2-inch ratchet driver or 24mm spanner to turn it when working on a compatible cassette lockring.

OneUp also specifies this tool for the EDC Threaded Top Cap and OneUp Aluminium Pedals, making it useful for more than a cassette change. It does not fit the internal lockring inside a OneUp rear hub; check the exact fitting rather than treating all lockrings as interchangeable.
