Park Tool CM-5.3 Cyclone Chain Scrubber

Clean your bicycle chain quickly, easily, and effectively, without removing it from the bike. The CM-5.3 features an extra-large solvent reservoir and four rotating brushes that scrub the chain inside and out. A magnet at the bottom of the reservoir collects particles scrubbed from the chain, preventing them from being redistributed. The durable sponge material wicks away solvent as it exits the tool, reducing drips and mess.

Compatible with all bike-specific chains, from wide 3/16" single-speed to narrow 12 and 13-speed chains, the CM-5.3 includes a reversible handle that allows the chain to pass through forwards or backward, making it suitable for center-drive e-bikes.

Key Features:

• 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 (part # RBS-5)

NOTE: 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.
