Park Tool Cyclone Chain Scrubber

Cleans bicycle chain quickly, easily, and effectively — without the hassle and mess of removing the chain from the bike. The Cyclone™ uses a large solvent reservoir, hundreds of rotating bristles, and a two-step cleaning process to get chains really clean, improve shifting performance, and extend the life of the chain and other expensive drivetrain parts.

Works with all multi-speed bikes (5, 6, 7, 8, 9, 10, 11, and 12-speed) as well as some single-speed models
Reversible body allows use on center and rear drive e-bikes
Strong magnet at the bottom of the fluid reservoir holds metallic particles scrubbed from the chain
Special wicking sponge draws solvent from the chain as it exits, minimizing drips and mess
Sturdy handle makes the Cyclone™ easy to use and control
Holds 2 fluid ounces (59ml) of solvent
