What about duralube or prolong, both treats the metal??? if it does what it says, once treated the metal of the chain and cassete should be protected. Most problems comes about when a chain is cleaned to often, more importantly what it is cleaned with, cause its that stuff that makes your chain shine, that hase washed out all the lube between the links. ive tried most lubes, this works for me. Clean all the crap from that chain, everything, even if it means putting it in petrol.. then wash it with soap and water and let it dry.. when you pick it up every bloody link should be making a noise. now lube each link with finish line wet lube. an hour later take a dry cloth and wipe it clean,clean,clean Put it back on your bike (clean your chain rings,cas and rear der wheels) Go ride. get back home wash whatever dirt is on it off with a hose. go ride The lube is inside, no need to cover the whole chain with it.
