Park Tool CG-2.4 Bicycle Chain and Drivetrain Cleaning Kit
A dirty bicycle drivetrain causes poor shifting and unnecessary wear to expensive parts.
The Park Tool Chain Gang contains everything needed to quickly and easily clean the chain, freewheel cogs, and chainrings. The Chain Gang includes a CM-5.3 Cyclone Chain Scrubber, a GSC-1 GearClean Brush, and an 8 oz bottle of CB-4 Bio ChainBrite.
To make the CM-5.3 easy to control and use, we've added a reversible handle, allowing the chain to pass through in either direction for compatibility with center drive e-bikes. Compatible with all multi and single-speed bikes as well as both center and rear drive e-bikes.
CM-5.3 Cyclone Chain Scrubber
Cleans bicycle chains quickly, easily, and effectively — without the hassle and mess of removing the chain from the bike. The Park Tool CM-5.3 Cyclone Chain Scrubber uses an extra-large solvent reservoir and a series of rotating brushes to get chains sparkling clean. A magnet at the bottom of the Cyclone’s solvent reservoir draws particles scrubbed from the chain, effectively keeping them from being redistributed on the chain during cleaning. The durable sponge material draws solvent from the chain as it exits the Cyclone, reducing drips and mess. The brushes and sponge of the CM-5.3 are replaceable (part # RBS-5).
GSC-1 GearClean Brush
Park Tool’s GSC-1 GearClean Brush has a unique design. A large comfortable handle with a curved, toothed-end reaches dirt deep between the gears, and tough nylon bristles clean the derailleur and chain. Saves wear and tear on your chain and freewheel. Works great on brakes or other places where dirt collects.
CB-4 Bio ChainBrite
Park Tool Bio ChainBrite Bicycle Chain and Component Cleaning Fluid is a 100% biodegradable, natural, plant-based degreaser formulated for use in the CM-5.3 Cyclone Chain Scrubber, or with a scrubbing brush as a general purpose degreaser. When used with a chain cleaner, CB-4 gets bicycle chains clean inside and out so they're good as new. Will not harm alloy, plastic, rubber, or carbon fiber parts, so it's safe to use for cleaning cassettes, chainrings, pulleys, or any other component that accumulates muck and grime.
