Rock n Roll Extreme Low Vapour chain lube not only lubricates your chain but it keeps it clean too.
This is a PTFE based chain lube. If applied correctly (dribbled on while back pedalling) the lube penetrates into the rollers and pins and forces any dirt out and then wipe the chain with a clean rag. Your are left with a chain that is protected from moisture and we'll lubricated. Chains with Rock 'n' Roll Extreme should not need further cleaning. The lubricant acts in such a way to prevent particulate build up, this is how it stays clean.
Us this once, you won't go back.
