This Silkolene Professional Care Pack Chain Lube and Cleaner contains a 500 ml aerosol of Silkolene Pro Chain Lube and a 500 ml aerosol of Silkolene Brake and Chain Cleaner. The Chain Cleaner, with a Smart Straw Applicator, is ideal for removing old chain lubricant from standard, O-ring and X-ring chains especially when used in combination with a tooth brush or a chain brush. The Silkolene Pro Chain, also fitted with the latest Smart Straw Applicator, is a fully synthetic racing chain lubricant which can be applied within minutes of the chain being cleaned. Silkolene Pro Chain, Professional Chain Lubricant, is highly viscous lubricant designed to penetrate the chains, rollers, pins and bushes and once the carrier solvent has evaporated leaves a thin, yet highly effective lubricating film. Offers excellent corrosion protection and resists shock loads, high temperature conditions and the exceptional G forces experienced in racing situations. For the best results Pro chain should be left overnight for its solvent carrier to evaporate. Both the Silkolene Motorcycle Brake and Chain Cleaner and the Silkolene Pro Chain Race Chain Lube are available separately.
