The Ultimate bicycle chain lubricant. absoluteBLACK GRAPHENlube is the world's first hydrocarbon-based (wax) chain lubricant containing Graphene. It exhibits extraordinary durability at single application whilst maintaining impressively low friction for a prolonged period of time in both wet and dry conditions. It's everything you can really wish for in lubrication. Up to 1800km on single application (dry conditions), 3-10W savings over other lubes. We have finally managed to break a "magic barrier" of 3W losses not only in dry conditions but also in wet for over 150km. Perfect for Road, Triathlon, Gravel, Mtb and E-bike.
