Park tool - Professional Chain Scrubber CM-25
Built for longevity and regular use, Park Tool's Professional Chain Scrubber CM-25 is made from extremely durable die-cast aluminium and contains top-quality brushes, giving consistent wash quality every time. The tool also contains wicking pads and dual-sided sponges to reduce drippage, as the rotating brushes make sure all four sides of each link get the best clean possible. The brush and sponge cartridges can be clicked in and out after each wash to dry out before their next use and the whole scrubber is 100% serviceable.
A fantastic bit of kit for keeping your ride in top condition, for any home mechanic or workshop.
