What Does the SR-12.2 Sprocket Remover Do?

The Park Tool SR-12.2 Sprocket Remover is built to remove individual sprockets from older freewheel clusters and multi-sprocket assemblies that use a pin spanner engagement. Its dual-pin design locks into the spanner holes on the sprocket and allows you to apply rotational force cleanly without slipping off the pins or rounding the engagement points. The SR-12.2 is the right tool when you need to remove a specific sprocket for replacement or adjustment on freewheel-style drivetrains that are still in active use on vintage and classic bikes.

Pin spanner engagement requires precise fit to avoid damage. The SR-12.2 is sized and manufactured to engage securely, so you can apply the torque needed to break loose tight sprockets without improvising with general-purpose tools that don't fit the hole pattern correctly.
