Overview

Is the FR-2 the Right Tool for Sun Tour Freewheels?

The Park Tool FR-2 is built for Sun Tour 2-prong freewheels, giving you the precise fitment needed to remove this classic freewheel standard without rounding off the drive notches. Machined from hardened steel, it drops into the two drive notches on your Sun Tour freewheel and transfers torque cleanly through a bench vise or wrench. Whether you're restoring a vintage road bike or servicing a classic commuter, the FR-2 handles the job that a universal tool cannot.

Older Sun Tour-equipped bikes are still rolling, and having a job-specific remover in your toolkit means you can tackle rear wheel service without improvising. The FR-2 is compact, durable, and works with standard shop equipment you already own.
