1. Chain and sprockets are perfectly cleaned, lubricated and protected against rust, which extends their life many times over. 2. Virtually no fling-off onto the rear tyre because the amount of lubricant is finely metered and it is applied and distributed with great precision, as confirmed by testing on the race track. 3. The lubricant is applied direct to the inner side of the chain. 4. Very economical use of cleaner and lubricant. 5. A chain maintained with the cleaner runs smoothly, without any slap, clanking or squeal.
