CM-5.3 CYCLONE™ CHAIN SCRUBBER

Clean bicycle chains quickly, easily, and effectively without the hassle and mess of removing the chain from the bike. The CM-5.3 uses an extra-large solvent reservoir and a series of four rotating brushes to get chains sparkling clean inside and out. A magnet at the bottom of the CM-5.3's solvent reservoir draws away 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 CM-5.3, reducing drips and mess.

The CM-5.3 can handle any bike-specific chain, from wide 3/16" single-speed* to narrow 12 and 13-speed. A reversible handle allows the chain to pass through forwards or backwards for compatibility with center drive e-bikes.

CB-4 BIO CHAINBRITE

Park Tool CB-4 is a 100% biodegradable, natural, plant-based degreaser formulated for use in the CM-5.3 Cyclone Chain Scrubber, CM-25 Professional 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.

GSC-1 GEARCLEAN™ BRUSH

The GSC-1 is specially designed to free your bicycle drivetrain from muck and grime. The comfortable handle features a contoured toothed end to reach dirt deep between the gears, and tough nylon bristles clean the derailleur and chain. Saves wear and tear on your chain and cassette. Also works great on derailleur pulleys, brakes, or other places where dirt collects.

The CG-2.4 is compatible with nearly any bike including multi-speed, single-speed, and e-bikes.
