Muc-Off Dry PTFE Chain Lube is formulated for bicycle chains to hold up to the extreme pressures that are applied to a modern drive chain. It"s a highly versatile, all weather chain lubricant which has superior penetration qualities ensuring that every part of the chain link is lubricated. Our advanced " Dry Formula" creates a clean, durable & protective layer which inhibits rust & corrosion. The added PTFE has exceptionally low surface friction to provide incredible drivetrain efficiency without attracting contaminants. It"s so clean & easy to use! Forget messing around with fiddly dropper bottles, simply spray on at a 45 degree angle to ensure maximum link coverage. Doesn"t leave a messy white residue unlike some other dry lubes.
