Park Tool CM-5.3 Cyclone Chain Cleaner

The Park Tool CM-5.3 Cyclone Chain Cleaner is a shop-proven tool for cleaning bicycle chains without removing them from the bike. It clamps around the chain and uses rotating brushes to scrub away grime while keeping solvent contained.

It’s designed for regular maintenance on multi-speed bikes and e-bikes where quick, effective chain cleaning helps extend drivetrain life and improve shifting.

Key Features
• Cleans the chain without removing it from the bike
• Rotating internal brushes scrub all sides of the chain
• Strong magnet traps metal particles pulled from the chain
• Wicking sponge reduces drips as the chain exits
• Holds up to 2 oz (59 ml) of solvent
• Sturdy handle for controlled, stable use

Compatibility & Use Notes
• Works with 5–12 speed drivetrains
• Compatible with many single-speed bikes
• Suitable for most e-bikes
• Not compatible with fully enclosed chain cases
• Requires liquid chain cleaner or degreaser (not included)

Service / Ownership Context
For best results, use a bike-specific chain cleaner and rotate the crank backward slowly during cleaning. After cleaning, allow the chain to dry fully and re-lubricate before riding. Regular chain cleaning reduces wear on cassettes and chainrings.
