Park Tool RBS-5 Replacement Brush Set for CM-5 Chain Cleaner

Posted by on in Tools


The sponge on my Park Tool CM-5 Cyclone Chain Scrubber became brittle and disintegrated after years of use. One of the first things I do on every bike I work on, is to wash it, and then clean and lube the chain. So the chain cleaner gets a lot of use. It still works without the sponge, but dirty degreaser splatters all over. So I wanted to get a new sponge, but couldn’t find just the sponge. I did find the RBS-5 Replacement Brush Set from Park Tool that came with two sponges and brand new brushes. In the video, I remove the old brushes and install the new ones.
