The Formula 100 Speed Clean Chain + Drivetrain Brush is designed to make deep drivetrain cleaning faster, easier, and more effective. Engineered with an innovative dual-brush design, this versatile cleaning tool reaches every part of your drivetrain to remove stubborn grease, dirt, and grime. Whether you&';re maintaining a road bike, mountain bike, eBike, or eMoto, the Speed Clean Brush delivers professional-level results while simplifying your regular maintenance routine. At the core of the design is a unique 360Adeg channel brush that surrounds the chain with dual-density bristles, allowing it to scrub both the inner and outer links simultaneously for a thorough clean. Longer bristles on the opposite end easily reach difficult areas around derailleurs, cassettes, jockey wheels, and chainrings, making it simple to remove buildup from every drivetrain component without the need for multiple tools. Designed for convenience as well as performance, the compact brush is equally at home in the workshop or packed in a gear bag for cleaning after muddy rides. When paired with Formula 100 Chain + Drivetrain Degreaser, the brush maximizes the effectiveness of Grease Release Technology, helping dissolve stubborn grease while safely cleaning all drivetrain surfaces for smoother shifting and longer component life. Developed by Formula 100, the Speed Clean Chain + Drivetrain Brush is an essential maintenance tool for riders looking to keep their drivetrain performing at its best.
