What Mountain Bike: "Muc-Off now does a range of lubes. This thick viscous wet lube is drip applied directly to the chain and should sit a few minutes to penetrate the insides of the rollers. It goes on easily and stays more or less where you put it. Because it's a drip applicator, it'll last a while too. The excess should then be removed with a dry, lint-free rag until the chain is spotless and shiny. Your chain is now protected for about 50 miles of hard riding - less if you're in a complete deluge or submerging the drivetrain in water. Remove with degreaser when done and repeat the process until the sun comes out again in spring".
