Park Tool CG-2.4 Chain and Drivetrain Cleaning Kit

Yes, the CG-2.4 is fully compatible with e-bikes, as well as multi-speed and single-speed drivetrains. The included tools are designed to handle the standard chain widths found on these bikes.

No, the CM-5.3 Cyclone Chain Scrubber is designed to be used while the chain is still on the bike. You simply clamp the tool over the chain, add the cleaning solution, and pedal backward to scrub the links.

The GSC-1 brush is specifically shaped to reach into the tight spaces between your freewheel cogs and chainrings. It features stiff bristles on one end for scrubbing and a hooked pick on the other to scrape out stubborn, impacted debris.

Bio ChainBrite is a biodegradable, water-soluble degreaser formulated to be safe for most bicycle components. However, it is always best practice to rinse the drivetrain thoroughly with water after cleaning to ensure no residue remains on your frame or painted surfaces.

Frequency depends on your riding conditions, but a general rule is to clean your drivetrain whenever you notice grit or a black, gummy buildup on your chain. If you ride frequently in wet or muddy conditions, you should clean it more often to prevent premature wear on your cassette and chainrings.
