No better way to thoroughly clean a chain.
by Bicycle Norm

The parts are used as replacements in the Park RBS-5 chain cleaning system. After cleaning many chains, especially wider ones, the bushes sort of wear out, which leads to reduced cleaning of the chain when used. By replacing the moving parts, the tool become fully functional again. Replacing the brushes is very easy and takes less than a minute. If you have the Park RBS-5 tool, check the inner brushes on the large rotating cylinder. These are the ones that wear the fastest.

My Park Tool chain washer brushes were not cleaning as effectively as new. This kit restored like-new functionality to the chain washer.

Does what it says on the packet

These make the Cyclone more durable and justify the initial outlay, but if you don't have a Cyclone Chain Scubber, they would be pretty rubbish, so I wouldn't recommend them then.

Be Smart - Refresh rather than Replace!!

I was not aware that replacement parts existed for the Park Tool Cyclone Chain Cleaner until I saw it on this site. The RBS-5 Replacement Brush Set gives new life to the best chain cleaner out there making it a great value. Keeping a clean chain helps save wear and tear on the cassette so it's a double great value!! Park Tool always delivers and they sure did this time!

Good enough

I keep my chain very clean since it improves shifting performance on my ultegra equipped bike. I had worn out the innards on my Cyclone Chain Scrubber and this replcement kit was alot cheaper than buying a new one. The replacement parts fit well and have worked well so far although one of the brushes lost a few bristles at first. Good buy.
