The water resistant chain and component oil Turmofluid 40 B has been successfully on the market for many years and suited to the steadily increasing demands of highly-efficient bicycle oils. Particularly noteworthy is its high adhesion. Even when subject to pressure and humidity, it protects reliably in low and high temperatures and offers a very good corrosion protection. The clear coloured oil prevents a blackening of the bicycle chain, caused by most chain lubricants.
