I've been using Rock-N-Roll Gold for several years now. I don't believe in magic and any lubricant will wear off or get dirty in time, but given my good experience with R-N-R Gold I decided to try Extreme during the Michigan winter. So far so good, it seems a little thicker than Gold and really made the chain quiet. I haven't tested it in real wet dirty conditions yet but I expect it will perform as advertised given my experience with Gold. Just my 2 cents and advice, get two or more chains and change them regularly. I remove the old chain, clean it, and then put it in a coffee can covered with lubricant. That way I always have a fresh chain waiting. If the chain that is currently in operation looks clean but is creaking, I just freshen up the lubrication.
Been using this for years. Great for dusty conditions. Chain stays cleaner than most other lubes Ive tried. Biggest plus is extended chain wear. I keep track of mileage on my chains. Always use a Park chain checker. Probably get 20% more mileage on my chains when using this lube. Less wear equals less rolling resistance. Only drawback is application. I saturate chain with this lube and it is messy. Learned to place old cardboard under bike when lubing chain. Keeps it off of my garage floor.
I choose Rock N roll over oil based lubricants as it simultaneously cleans and lubricates. The wax lubricates but attracts less dirt which should reduce link wear. No black, dirt filled, solidified oil accumulation on chain, cassette, rings, bike frame, clothing or fingers!
I have been using this chain lube for a little more than a year. It seems to work very well and the chain doesn't seem to retain dirt nearly as easily as with some other brands. This lube also has some very low rolling resistance numbers associated with it from some independent tests I've seen reported on the internet.
