    My second one!

    • Familiarity: I've put it through the wringer

    I bought this brush to replace the one I wore out. Perfect for cleaning the cogs. I use Dumonde Tech lube on the chain, which can be messy. Pedro's Bio degreaser along with the Park chain cleaner and this brush makes for a quick and thorough cleaning of the drivetrain.


    • Familiarity: I've used it several times

    Pretty stoked on such a simple piece. I've historically been someone who doesn't keep my bike super clean. But having this brush makes scrubbing down my cassette after every few rides a quick and easy ritual.

    Park tool brush

      These brushes are fantastic, and any bike cleaning bucket should ALWAYS have one of these in it. The bristles are long enough to get to all the gaps in the cassette, and it will get into all the little nooks and crannies you can imagine. It also has the plastic shape at the other end that can be used to get hardened grease or mud or grit out of the cassette and other components/parts.
