The smooth-shifting feeling of a fresh chain is hard to beat, and while you’ve spent countless hours keeping yours spotless, there’s only so much you can do before the brushes in your chain cleaner are gunked up and doing more harm than good. Fortunately, Park Tool has you covered with the Replacement Brush Set for CM-5 and CM-5. 2 chain cleaners. These brushes and sponges easily replace the original brushes to freshen up your chain cleaner without feeling like you need to kick it to the curb. It comes along with three brushes for scrubbing down your chain, and two sponges to catch the drips off and leave you with a chain that’s almost like new.
