Park Tool Cyclone Chain Scrubber

The Cyclone is designed to work with most 5- to 11-speed multi-speed drivetrains and select single-speed configurations. It is not compatible with some specialty chains, such as those found on internal gear hubs or e-bikes with specific chain guards.

No, that is the main benefit of this tool. It clamps directly onto the chain while it is still on the bike, allowing you to clean it thoroughly without any disassembly.

You should use a dedicated bicycle chain cleaning fluid or a biodegradable degreaser. Avoid using harsh solvents like gasoline or kerosene, as these can damage the plastic housing of the tool and strip the lubricant from inside the chain rollers.

The reservoir has a capacity of 2 fluid ounces. It is designed to be large enough to submerge the brushes and chain links effectively without needing constant refills during a single cleaning session.

While it is significantly cleaner than scrubbing by hand, some solvent splatter is possible if you pedal the chain too quickly. We recommend placing a rag or a piece of cardboard under the drivetrain to catch any drips.
