  • 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.
