  • Bikerumor: Winter Maintenance Tips The first step to cleaning a bike is to degrease all of the dirty parts because a regular “bike wash” solution won’t cut through the oil soaked grime. To conquer this feat, Park Tool‘s’ new CM-25 shop level chain scrubber came to the rescue. The die-cast aluminum casing & handle on Park’s newest chain cleaner is strong enough to stand on (don’t) and houses 4 scrubbing stages that the chain passes through.

  • CyclingTips: Park Tool CM-25 Chain Cleaner Review I’ve tried many chain cleaning tools over the years, and while some have been better than others, I’ve managed to either break or wear out every single one of them – a feat that shouldn’t be so surprising when you consider that all of them have been made of plastic. All, except for Park Tool’s CM-25 Professional Chain Cleaner.
