The stickiest, thickest lube that Rock N Roll makes, Extreme Lube is intended to keep your chain silky in the gnarliest, nastiest conditions, from ruinous 'cross races to sloppy enduro stages and the pig-sty slop of a muddy DH race. The synthetic lube contains a suspended gel membrane that seeps into pins and rollers to keep things your chain smoothly and your cogs de-gunked.
