Extreme Lube is the most viscous of Rock n Rolls lube formulations. Its for the nastiest, gnarliest, wettest, and muckiest conditions. Extreme Lube has a gel membrane suspended in the fluid. The membrane seeps deep into the rollers of each pivot, keeping the chain joints flexing, moving smoothly, shifting crisply, and doing everything quietly.Rock n Roll lube cleans and lubes at the same time. Dribble it on by putting the bike in its biggest gear and backpedal. Drip from the top over the chainring or cog. Wipe off the excess. Shift to the small ring in front to wipe off the big ring. Wipe till the chain shines. You can ride right away, but letting the excess evaporate for a few hours or overnight is best. And, despite the fact that this is Rock n Rolls wettest lube, its still drier and cleaner than much of whats available on the market. Rock n Roll recommends not re-lubing until you hear squeaking. If you have more than one Rock n Roll lube in your tool chest, you can put on the thicker formulations when its wet and then apply the thinner when its dry and you dont have to degrease in between.
