Cassettes collect grime between cogs where standard brushes can't reach, and derailleur pulleys pack mud into every groove until shifting starts to suffer. The Muc-Off Claw Brush consolidates three different brush heads and an integrated scraper into a single tool designed specifically for drivetrain cleaning. Instead of switching between brushes or improvising with worn-out household tools, you get purpose-built bristle configurations for the chain, cassette, chainrings, and derailleur components.

The three brush heads use stiff nylon bristles at different lengths and densities. Longer bristles reach deep between cassette cogs to dislodge the compacted grime that accumulates during wet rides. Medium-length bristles scrub chain plates and rollers where degreaser needs agitation to break through old lubricant. Shorter, denser bristles work the tight spaces around derailleur pulleys and cage plates where dirt gets packed in.

The integrated scraper handles the truly stubborn stuff — caked mud on cleats, debris packed into pedal bodies, or grime buildup on jockey wheel teeth that bristles alone won't dislodge. It also works for clearing mud from tire treads before you start washing the rest of the bike.... Read More
