Chain Star “Extrem” is a unique grease based, two-component chain lubricant for high performance use. Thanks to its special composition it flows easily onto the chain and in between its contact surfaces, where it displaces moisture, lubricates and protects against corrosion. Compared to Chain Star “Normal”, it contains more adhesive components and is therefore perfectly suited for chains on mountain bikes operating in extreme weather conditions involving heavy rain, sticky mud, sand and snow. It is so powerful that it can also be used on chains of motocross and high-speed motorcycles. If applied correctly it is perfectly usable in dry conditions as well.
