CM-5.3: 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 centre 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
