Overview
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.

Good questions
Get to know Park Tool

There's more to Park Tool than this one product. Our Park Tool page has the full Park Tool lineup we carry and more about the brand.
Visit the Park Tool page →What type of drivetrains is the SR-12.2 designed for?
The SR-12.2 is designed for older freewheel-style drivetrains that use individual threaded sprockets with pin spanner engagement points, commonly found on vintage road and utility bikes.
Will the SR-12.2 work on modern cassette sprockets?
No. The SR-12.2 is a freewheel-era sprocket tool and is not compatible with modern cassette sprockets, which use a different engagement and removal system.
Do I need a freewheel remover as well as the SR-12.2?
Yes. The SR-12.2 removes individual sprockets from a freewheel cluster. You still need a freewheel remover to take the entire freewheel body off the hub.
