The FR‑5.2 from Park Tool is a special tool for removing and reinstalling the cassette lockring — that is, the gear cluster on the rear of the bicycle that screws onto the freehub.
Compatibility:
-
Fits most 7‑12 speed cassette lockrings from Shimano®, SRAM®, and other manufacturers.
-
There is no need to remove the cones or axle nuts for it to work.
Construction:
-
Made from high-strength, tin-plated tool steel for long durability.
-
The thin walls of the tool allow access even when there is limited space around the system.
How it works:
-
The tool has 12 internal splines that match the corresponding splines on the cassette lockring.
-
The base of the tool is a 1″ hex, so you can use a wrench, socket, or rubber handle to turn it.
-
The center bore allows space for a 12 mm axle.
Usage:
Mainly used for:
• Removing the cassette when you want to clean or replace it.
• Installing the cassette again correctly.
