Park Tool CM-5.3 Cyclone Chain Scrubber

The Park Tool CM-5.3 Cyclone Chain Scrubber lets you easily clean your bike chain without removing it from the bike! Using an internal solvent reservoir and a series of four rotating brushes, the Cyclone Chain Scrubber gets your chain sparkling clean and keeps the mess to a minimum. A magnet at the bottom of the solvent reservoir also draws away particles scrubbed from the chain, effectively keeping them from being redistributed on the chain during cleaning.
The Park Tool Cyclone Chain Scrubber can handle any bike-specific chain, from wide 3/16" single-speed* to narrow 12 and 13-speed. A reversible handle allows the chain to pass through forwards or backwards for compatibility with center drive e-bikes.

• Compatible with all multi and single-speed chains*
• Compatible with center and rear drive e-bikes
• Holds 59 mL (2 fl. oz.) of solvent
• Replaceable brushes and sponge 

*All standard bicycle chain sizes will fit through the CM-5.3. However, some single-speed bikes are not fully compatible with the CM-5.3 due to the low clearance between the chain and chain stay.
