2. What Is the Park Tool CM-25 Professional Chain Scrubber?
While the term “scrubber” often brings to mind an electric spin scrubber used for bathroom tiles or kitchen grout, the Park Tool CM-25 Professional Chain Scrubber is a specialized mechanical tool for cyclists.
Unlike a typical electric spin scrubber meant for home surfaces, this is a “manual-motion” tool where the energy comes from backpedaling the bicycle. It is a “shop-quality” version of the popular plastic Cyclone cleaners, upgraded to 2026 standards with even more durable materials intended for daily professional use.
3. How It Works
The CM-25 operates using a mechanical interface that surrounds the chain.
- Rotating Brush Head: Three internal brushes rotate as the chain moves through them, scrubbing all four sides of the links simultaneously.
- Fluid Reservoir: The aluminum body holds degreaser, submerging the chain in a cleaning bath as it passes through.
- Interchangeable Heads: The entire internal brush and sponge set is a single cartridge (RBS-25) that can be swapped out when the bristles eventually wear down.
