Rock "N" Roll Gold chain lube is the lube everybody is after thanks to its top drivetrain efficiency rating in a recent cycling publication. In case you didn't read the article, about 30 of the most popular lubes were tested for drive train efficiency in a laboratory setting. Rock "N" Roll was the clear winner with the least amount of friction losses - about 1 watt more efficient than most lubes at a 250 watt load. Of course the lube with the least friction may not be the best lube in terms of longevity, riding conditions, maintenance intervals, etc. but if you want a scientifically proven fast lube, get Rock "N" Roll Gold.
The Secret to Rock "N" Roll Gold are large amounts of PTFE and a bit of light oil in a carrier. This lube is very light and formulated to clean and lube at the same time when applied. 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. The lube gets down inside the chain to create a protective membrane to seal out dirt and moisture from the moving parts of the chain and stays in place for longer chain life and super smooth shifting.
To apply, put a nice flow of lube go onto the chain because you're going to clean and lube the chain in one step. Freewheel the chain backwards, and wipe off all of the dirt and grit that comes up to the surface of the chain. Keep in mind, you can't wipe off the chain too much. For best results, allow your chain to sit a few hours or lube the night before. Giving the lube a chance to set gives the lube a bit more life by allowing the protective membrane to fully set-up.
