The Park Cyclone Chain Scrubber is a versatile tool that works with all multi-speed bikes (5-12 speeds) and some single-speed and e-bikes. Its magnetized fluid reservoir removes metallic particles from the chain, while a wicking sponge draws out excess solvent, reducing drips and mess. Its strong handle and 59ml capacity make it easy to use and control. Get your chain clean with this powerful and efficient machine.
