Purple Extreme Performance Synthetic Chain Lubricant, High Mileage

Purple extreme was originally formulated to protect drive chains in the mining business and on offshore oil rigs, in some the harshest conditions imaginable, for months at a time. Purple extreme has extremely high film strength, way beyond most conventional chain lubrication products available within the bicycle industry. The ability of a lubricant to keep two surfaces separated is called film strength. Our film strength is second to none. The ASTM D 2782 test (Timken extreme pressure test) is one of the laboratory methods used in determining the load carrying capacities of oils and greases. In this test, a Timken bearing cup is rotated against a steel block. The highest load under which a lubricant prevents scoring (caused by contact) of the steel block by the rotating cup is the reported value. Our dare-to-compare live demonstrations using a Timken machine have consistently and conclusively proven purple extreme's ability to keep metal surfaces separated. Purple extreme has a Timken ok load in excess of 90. No other bicycle chain lubricant has ever exhibited film strength even remotely close to purple extreme. What does that mean to our customers? Simple, less wear. Like an insurance policy, this extraordinary film strength provides extra protection for bearings and surfaces subjected to mechanical stresses. Your equipment lasts longer, runs smoother and cleaner, with less frequent applications of lubricant.
