Park Tool CM-5.3 - Chain cleaning device

Cleans the bicycle chain quickly, easily, and effectively - without the additional effort of removing the chain from the bicycle. The chain cleaning device uses a large solvent container, hundreds of rotating bristles, and a two-stage cleaning process to effectively clean chains, improve shifting performance, and extend the life of the chain and other expensive drivetrain components.

Features:

• Works with all multi-speed bicycles (5, 6, 7, 8, 9, 10, 11, and 12-speed) as well as some single-speed models
• Reversible body allows use on e-bikes with mid and rear-wheel drive
• Strong magnet at the bottom of the fluid container holds metal particles washed off the chain
• Special sponge with wicking action absorbs the solvent as it exits the chain, minimizing drips and dirt
• Thanks to the sturdy handle, the Cyclone™ is easy to operate and control.
