A dirty drivetrain causes poor shifting and unnecessary wear to expensive parts. The CG-2.4 contains everything needed to quickly and easily clean the chain, cogs, and chainrings:

CM-5.3 Cyclone Chain Scrubber
Quickly and effectively cleans chains without removal using four rotating brushes and a large solvent reservoir. A built-in magnet traps debris, while a sponge minimizes drips. Compatible with all bicycle chains, including 3/16" single-speed and 12/13-speed. Reversible handle works with center-drive e-bikes.

CB-4 Bio ChainBrite
A 100% biodegradable, plant-based degreaser safe for use on metal, plastic, rubber, and carbon. Ideal with Park Tool chain scrubbers or for general cleaning of chains, cassettes, chainrings, and pulleys.

GSC-1 GearClean Brush
Tough nylon bristles and a contoured gear-end clean deep between gears, derailleurs, pulleys, brakes, and other hard-to-reach areas to reduce drivetrain wear.
