Bikes, being on rubber tyres, are not grounded, making them a static electricity machine. As the bike rolls along, positive charge build up will bring dirt and dust particles from the road or trail onto the bike. The bike will then discharge and do it all over again, bringing up more dirt. Formulated to give maximum protection, excellent adhesion, cleaning and lubricant properties the Gold Chain Lube removes rust, dirt and grime from chains. Reduces friction for longer chain and sprocket life and resists water wash off to retard rust and corrosion.
