Effortlessly and efficiently clean bicycle chains without the need to remove them from the bike. The CM-5.3 features an oversized solvent reservoir and four rotating brushes that thoroughly clean chains both inside and out. A magnet at the bottom of the CM-5.3's solvent reservoir captures particles removed from the chain, preventing them from being redeposited during the cleaning process. The durable sponge material absorbs solvent from the chain as it exits the CM-5.3, minimizing drips and mess. The CM-5.3 is compatible with any bike-specific chain, ranging from wide 3/16" single-speed* to narrow 12 and 13-speed chains. Its reversible handle allows the chain to move through in either direction, making it suitable for center drive e-bikes. Suitable for all multi-speed and single-speed chains* Works with both center and rear drive e-bikes Solvent reservoir capacity: 59 mL (2 fl. oz.)
