Johan Bornman Quotes & Sayings

The science of lubrication, friction and wear is called tribology and is a branch of mechanical engineering. Tribologists are employed by lubricant companies, bearing manufacturers, vehicle brake manufacturers and just about anywhere you can expect to solve a problem of friction and wear. Tribologists agree that the best lubricant for roller chains is viscous oil, not wax, graphite, or silicone. Yet, you'll often find a new chain lubricant on the market that promises an improvement (they never say over what) and that chains will not suffer the same side effects as when lubricated with oil. Approach these products with sceptical caution. If the manufacturer uses words like "dry", "wax", and/or "clean", it is probably not a quality chain lubricant. Its sole redeeming feature may be that it doesn't turn black with use, itself a sign of poor lubrication. We'll discuss discolouration of the oil in due course. — Johan Bornman
