Tool Park Tool FR-5.2 Cassette Lockring Black

The Park Tool FR-5.2 is a cassette lockring tool for removing and installing cassettes and splined disc rotor lockrings.

• Fit: 12-spline lockring fitting used by Shimano, SRAM and many other cassette brands
• Design: Open center without a guide pin, so it works on thru-axle hubs and other hubs with the axle removed
• Base: 1-inch hex for a socket, wrench or bench vise
• Material: Heat-treated alloy tool steel

Pair it with a chain whip to hold the cassette while loosening the lockring.
