Abstract
A light-duty, multi-purpose lubricant particularly formulated for use on the diverse bearing surfaces of a bicycle chain and other similar low-speed and low-temperature mechanisms operating in a dusty environment. The lubricant comprises an insoluble soap, preferably Calcium Stearate in suspension in a volatile solvent-based solution of paraffin wax and Petrolatum. After application and evaporation of the solvent the composite dry lubricant exhibits good penetration and load bearing properties without the dirt-retaining character of greases. The undissolved particles of soap combine with dirt particles to break-down portions of the lubricant into a dry flaky dust which is sloughed off the mechanism.
