Excellent chain cleaner for home use
I've been using the CG-2.4 for a few months now, and it makes cleaning my bike's chain so much easier. The brushes get into every nook and cranny, and I love how compact it is for storage. Definitely worth the investment.

Works well but requires some elbow grease
This cleaning system does a great job at removing grime, but you need to pedal manually to get the chain through the brushes. It’s not motorized, so it takes some effort, but the results are definitely worth it.

Great for all chain sizes
I have multiple bikes with different chain speeds, and the CG-2.4 cleans them all effectively. The design is user-friendly and easy to maintain. My chain runs smoother and lasts longer after using this regularly.

★★★★☆
Solid design but brushes wear out
The cleaning system itself is very solid and effective, but after heavy use, the brushes started to show wear. Still, it’s easy to clean and replace brushes, so it’s a minor downside for the great cleaning performance.
