Park Tool Chain and Drivetrain Cleaning Kit (CG-2.4)

A dirty drivetrain causes poor shifting and unnecessary wear to expensive parts of your bike. The CG-2.4 package contains everything you need to quickly and easily degrease the chain, cogs, and chainrings, keeping any mess as contained as possible. 

CM-5.3 Cyclone™ Chain Scrubber
Clean your chain quickly, easily, and effectively with minimal mess and without removing the chain from the bike. The extra-large solvent reservoir and a series of four rotating brushes gets chains sparkling clean inside and out. A magnet at the bottom of the reservoir draws away particles scrubbed from the chain, keeping them from finding their way back onto the chain. A sponge draws solvent from the chain as it exits, reducing drips and mess. 

CB-4 Bio ChainBrite
Park's Bio ChainBrite degreaser is 100% biodegradable, natural and plant-based. It can be used in their chain scrubbers or with any scrubbing brush as a general purpose degreaser. Will not harm alloy, plastic, rubber, or carbon fibre parts, so it's safe to use for cleaning cassettes, chainrings, pulleys, or any other component that accumulates muck and grime. Also sold separately. 

GSC-1 GearClean™ Brush
This narrow brush is specially designed to free your bicycle drivetrain from muck and grime accumulated deep between your gears. Tough nylon bristles clean the derailleur and chain, saving you from wear and tear on your drivetrain but also works great on derailleur pulleys, brakes, and anywhere else dirt collects.
