The FRW-1 is a one-inch socket that securely holds Park Tool freewheel and cassette lockring tools (FR-1.3 through FR-8, and BBT-5/FR-11) for removal and installation. Features an investment cast head with locking setscrew and a long, round, vinyl dipped handle for superior leverage.

NOTE: Always use a skewer or axle nut to hold a cassette/freewheel tool in place during removal.
