Rock'N'Roll lubes use a special formulation that goes deep down into the chain and traps any dirt. Then, with the energy of the chain freewheeling backwards, the dirt and grit floats to the surface so you can wipe it all off, leaving a new and clean application of lube inside the chain, where it’s needed.
Rock'N'Roll offers 4 types/colours of chain lubes. Blue - Extreme is specially designed for mountain bikes. Red - Absolute Dry is for road bikes. Gold - Dry lube that works on Mountain bikes and Road bikes. White - Holy Cow is a wet lube for road bikes that looks drier than most dry lubes in the market. All of these are formulated to clean and lube at the same time.
