Put that old paintbrush away - there’s a new boy in town. Reaching the deepest and darkest parts of your drivetrain can be a challenge without the right tool so that’s why we have developed our high-quality Muc-Off Drivetrain Detailing Brush. Boasting a mean all-black finish, this is the perfect addition to your bike cleaning kit and is the easiest way to apply our Bio Drivetrain Cleaner to your chain, cassette, mechanics and sprockets. The Drivetrain Detailing bike brush allows you to reach even the tightest of areas to ensure maximum coverage and hassle-free post-ride bike cleaning.*To maintain performance of all bike cleaning brushes, avoid use with boiling water and on hot parts. We recommend using warm water and allowing all hot parts to cool before use.
