Rock-N-Roll Gold lubricant is for both mountain and road bike use. The formulation 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. - All-purpose lube - Cleans and lubricates simultaneously

Rock-N-Roll Extreme is a very clean lubricant due to its ability to shed dirt and dust. - For mountain bike or wet road riding
